make: do not use __CONCAT and __STRING in meta_needed

Using __CONCAT for identifiers makes it impossible to find their usages
easily, as could be seen in targ.c 1.22 from 2001-07-03.  It also
requires that the parts of the identifier are not macros themselves.

No binary change.

make: use unsigned int for line numbers everywhere

Previously, some line numbers were stored as signed int while others
were stored as size_t.  Since line numbers are never negative, use an
unsigned type.  Since the maximum file size for makefiles is 1 GB (see
loadfile), unsigned int is large enough even on 64-bit platforms.

Using a single data types reduces the number of type conversions.  Using
unsigned int improves compatibility with C90 (printf %u instead of %zu),
which is needed by bmake, which is derived from usr.bin/make.

No functional change.

make: clean up eat_dots for meta mode, part 2

At least on OpenBSD, "If the src and dst strings overlap, the behavior
is undefined" (since 2013-09-25), so rather use memmove instead.

Keep all other bugs for now, for example "/a/b//../" is reduced to
"/a/b/" instead of the correct "/a/", and for repeated "/././././" in
long paths, the performance is quadratic instead of linear.

Inline the two calls to eat_dots, turning the first into a two-liner.

make: replace enum bit-field with struct bit-field for VarEvalFlags

This makes the code easier to read, especially in var.c.  It also makes
debugging sessions easier since some debuggers don't show enum
bit-fields symbolically as soon as more than one bit is set.

The code outside var.c is basically unchanged, except that instead of
passing the individual flags, there are 4 predefined evaluation modes.
These suffice for all practical use cases.  Only in the implementation
deep inside var.c, the value of the flags keepDollar and keepUndef
differs.

There is no way of passing the struct to EnumFlags_ToString, which means
the ToString function has to be spelled out explicitly.  This allows for
fine-tuning the representation in the debug log, to reduce the amount of
uppercae letters.

No functional change.

make: rename some VAR constants to SCOPE

The word "context" does not fit perfectly to the variables that are
associate with a GNode, as the context is usually something from the
outside and the variables are more like properties inherent to the
GNode.

The term "global context" fits even less.  Since the thing where
variables are looked up is commonly named a scope, use that term
instead.

This commit only renames the global variables VAR_GLOBAL, VAR_INTERNAL
and VAR_CMDLINE, plus a few very closely related comments.  These are:

	GNode.vars (because of line breaks)
	GNode_Free (dito)
	varname-make_print_var_on_error.mk
	varname-make_print_var_on_error-jobs.mk

The debug message in Var_Stats is left as-is since there is no unit test
for it yet.

The other renamings (variable names "context", "ctxt", as well as
further comments) will be done in a follow-up commit.

There are several calls that remain syntactically unchanged but that
omit the call to strchr('$') now.  Since all these calls use constant
variable names, there is no functional change.

make: use shortcut functions Global_SetExpand and Global_AppendExpand

There are many places where global variables are set or appended to.  To
reduce clutter and code size, encode the VAR_GLOBAL in the function
name.

The word Expand in the function names says that the variable name is
expanded.  In most of the cases, this is not necessary, but there are no
corresponding functions Global_Set or Global_Append yet.

Encoding the information whether the name is expanded or not in the
function name will make inconsistencies obvious in future manual code
reviews. Letting the compiler check this by using different types for
unexpanded and expanded variable names is probably not worth the effort.
There are still a few bugs to be fixed, such as in SetVar, which expands
the variable name twice in a row.

make(1): consistently use boolean expressions in conditions

Most of the make code already followed the style of explicitly writing
(ptr != NULL) instead of the shorter (ptr) in conditions.

The remaining 50 instances have been found by an experimental,
unpublished check in lint(1) that treats bool expressions as
incompatible to any other scalar type, just as in Java, C#, Pascal and
several other languages.

The only unsafe operation on Boolean that is left over is (flags &
FLAG), for an enum implementing a bit set.  If Boolean is an ordinary
integer type (the default), some high bits may get lost.  But if Boolean
is the same as _Bool (by compiling with -DUSE_C99_BOOLEAN), C99 6.3.1.2
defines that a conversion from any scalar to the type _Bool acts as a
comparison to 0, which cannot lose any bits.

make(1): clean up make.h, meta.c, parse.c, str.c

The main changes are in the comments, which have been shortened and
corrected.

Some local variables changed their names.

In ParseErrorInternal, the scope of va_start is now narrower.

In ParseDoDependency, the type of tOp has been fixed.

ParseGetLine doesn't take flags anymore but instead a parsing mode.
Previously, the flags had not been combined anyway.

At the beginning of Parse_File, fatals is already guaranteed to be 0, and
even if not, it would be wrong to just discard the fatal errors.

make(1): remove redundant struct make_stat

In the cache for stat(2) and lstat(2), only one of the two timestamps
was ever used.  To prevent a result from stat(2) leaking into the cache
for lstat(2), there have been two completely separate caches all the
time.  Using different fields in the struct was therefore unnecessary.

By removing the redundant field, the internal struct in the cache is the
same as the external struct.  This makes one of them redundant, thus
struct make_stat has been renamed to cached_stat, which better describes
its purpose, and the internal struct cache_st has been removed.

Just as before, the cache prevents any direct access to its internal
data.  When passing it to the caller, it is copied.

Just as before, the field names of struct cached_stat cannot correspond
to those from struct stat, since the latter are often defined as macros.
Therefore they are prefixed with cst instead of st.

The redundancy had been added on 2020-06-05.

make(1): clean up code stylistically

* Replace character literal 0 with '\0'.

* Remove redundant parentheses.
* Parentheses in multi-line conditions are not redundant at the
  beginning of a line.
* Replace a few !ptr with ptr == NULL.
* Replace a few ptr with ptr != NULL.
* Replace (expr & mask) == 0 with !(expr & mask).
* Remove redundant braces for blocks in cases where the generated code
  stays the same.  (Assertions further down in the code would get
  different line numbers.)
* Rename parameters in CondParser_String to reflect the data flow.
* Replace #ifdef notdef with #if 0.

NetBSD 8.0 amd64 using the default configuration.

make(1): make memory allocation simpler in meta_create and meta_oodate

Since there is only a single variable left that needs to be freed at the
end (and probably never actually needs to be freed since nobody defines
an environment variable named .OBJDIR), there is no need to loop over
these variables.

make(1): do not look up local variables like .TARGET anywhere else

Nobody defines a global variable named .TARGET since that would have
many unpredictable effects, applying to all targets at once.

Nobody defines an environment variable named .TARGET since that's
against the naming conventions for environment variables and would have
the same effect.

Because of this, there is no point looking up the variables that are
local to a GNode anywhere else.  This means they cannot come from the
environment and thus their value doesn't need to be freed after use,
which makes the code simpler.

The newly added accessor functions in make.h refer to external
functions, but since that header is not used anywhere outside of
usr.bin/make, it doesn't matter.  Between 2020-08-25 and 2020-10-30,
that header had been referenced by usr.bin/xinstall.

make(1): make Lst_RemoveIf simpler in meta_oodate

Using Lst_Find and Lst_FindFrom to implement Lst_RemoveIf was a bad
idea.  It made the code much more complicated than necessary.  There is
no predefined Lst_RemoveIf, but that can be implemented easily.  By
inlining the list handling, path_match does not need void pointers
anymore.

Freeing the path from the missingFiles list had been implemented in a
surprisingly complicated way, intermangling it unnecessarily with the
list operations, even though these are completely independent.

make(1): inline simple Lst getters

The function call variant takes more screen space than the direct field

simple read-only member access it makes the code more difficult to read.

LstNode_Set has been kept as a function since it is not a read-only

make(1): rename Lst_ForEach to Lst_ForEachUntil

Since the callback function returns a terminating condition, this is not
really a foreach loop.

Many of the calls to Lst_ForEachUntil don't make use of the terminating
condition, and several don't modify the list structurally, which means
they don't need this complicated implementation.

In a follow-up commit, Lst_ForEach will be added back with a much
simpler implementation that iterates over the list naively, without a
terminating condition and without taking the iteration state from
Lst_Open/Lst_Next/Lst_Close into account.  The migration to this simpler
implementation will be done step by step since each callback function
needs to be examined closely.

These typedefs are only intended to help human readers, they do not

'*' is less work than finding out which of the many types are pointers
and which aren't.

In meta.c, the variable "ln" served two completely different purposes,
which have been split again.  Register allocation is the job of the
compiler, not of the human source code reader.

The fields in struct make_stat are intentionally named different from

systems define st_mtime as a macro, and that would not work in a field
declaration.

There were 2 surprises: The targets list may be NULL, and in Dir_AddDir,

that function turns into an almost-nop in that case.  This is another

single function.  This may be improved in a follow-up commit.

All other lists were fine.  They were always defined and thus didn't

by make.

These programming errors are now caught early by assertions.

make(1): make list library code stricter

Up to now, the list library didn't distinguish between programming
mistakes (violations of invariants, illegal parameter values) and
actually interesting situations like "element not found in list".

The current code contains many branches for conditions that are neither
exercised by the unit tests nor by real-world usage.  There is no point
in keeping this unnecessary code.

The list functions will be migrated from their lenient variants to the
stricter variants in small parts, each function getting the S suffix
when it is made strict, to avoid any confusion about how strict a
particular function is.  When all functions have been migrated, they
will be renamed back to their original names.

While here, the comments of the functions are cleaned up since they
mention irrelevant implementation details in the API comments, as well
as "side effects" that are really main effects.

The list library had probably been imported from a general-purpose
library that also supported circular lists.  These are not used by make
though.

After replacing Lst_Init(FALSE) with Lst_Init(), only a single call to
Lst_Init remained with a non-constant argument, and that was in
Lst_Concat, which was to be expected.

make(1): no declaration-after-statement anymore

NetBSD make is intended to be maximally portable, therefore it uses only
C89.  This was not declared in the Makefile before.

There are still a few places in parse.c and metachar.c that use
end-of-line comments.  These will be fixed in a follow-up commit.

make(1): remove dead code from Var_Subst

The first parameter from Var_Subst had been a literal NULL in all cases.
These have been fixed using this command:

sed -i 's|Var_Subst(NULL, |Var_Subst(|' *.c

The one remaining case was not found because the "NULL," was followed by
a line break instead of a space.

The removed code probably wouldn't have worked as expected anyway.
Expanding a single variable to a literal string would have led to
unexpected behavior for cases like ${VAR:M${pattern}}, in case pattern
would contain an unescaped ':' itself.

make(1): rename Varf_Flags to VarEvalFlags

In var.c there are lots of different flag types.  To make any accidental
mixture obvious, each flag group gets its own prefix.

The only flag group that is visible outside of var.c is concerned with
evaluating variables, therefore the "e", which replaces the former "f"
that probably just meant "flag".

continue using /dev/filemon on FreeBSD (which has seen more

Refactor the logic for deciding when a .meta file is needed.

Both meta_create() and meta_oodate() now share meta_needed()
to indicate if a .meta file is needed.

This allows for deciding that missing .meta file is cause of out-of-date.
The new knob 'missing-meta' controlls this, and is off by default
since the side effect files of generators like yacc will typically need
.NOMETA to avoid problems.

This however makes it much easier for folk to switch back and forth
with meta mode (eg. FreeBSD's normal build can leverage meta mode for
improved reliablility without need to clean).

Also if .MAKE.MODE does not contain 'nofilemon', the knob
'missing-filemon' allows control as to whether missing filemon data
should cause the target to be out-of-date.
Again off by default.

In meta mode, we create .meta files for most targets.
These capture all the interesting data - useful for debugging.
In such cases there is no need to replicate commands in the build log.
Rather than run the entire build .SILENT, allow meta mode to set that flag
per target iff a .meta file is created.
Normal behavior is retained for targets where no .meta file is created,
ensuring that no build data is lost.

When a source file moves, make will ignore the stale dependency,
but if the file in question is one that needs to be compiled (.c or .cc),
it still hands the bogus name to the compiler.

If Dir_MTime() cannot find such a file (gn->iParents is not empty),
see if the basename can be found via .PATH, and if so set gn->path to
the found file.   This prevents the stale path being given to the
compiler.

In meta_oodate(), if a referenced file no longer exists, consider the
target out-of-date.

Also, if meta_oodate() decides a target is out-of-date, and it
it uses .OODATE in its commands, we need .OODATE recomputed.
Undo our call to Make_DoAllVar() so that the call from Make_OODate()
will do the right thing.

Add meta.c which implements "meta" mode for make.
In this mode, a .meta file is created for each target, capturing
the expanded commands used, any command output, and if filemon(9)
is available, a record of system calls which are of interest.
Not enabled unless USE_META=yes is set when building make.
Also, if FILEMON_H exists, meta.c will be compiled to use filemon(9).
