make: fix error message for undefined variable in conditional

Previously, only ${UNDEF} had the proper error message, while
${UNDEF:M*} still produced the wrong "Malformed conditional".

make: add ":" to error message about unknown modifier

In the manual page, the modifiers are listed with a preceding ":", so
use the same pattern in the error message. This removes an inconsistency
between the error messages "Unknown modifier" and "Bad modifier".

make: omit redundant follow-up message "Malformed conditional"

If there is a parse error or an evaluation error during the conditional,
the conditional is already mentioned in the "while evaluating condition"
line, so there's no reason to repeat it once again.

Same for the "Bad condition" message from the '?:' modifier.

tests/make: force correct order of expected messages

make: reduce line length in error messages

The error messages for deeply nested parse errors were hard to decipher,
due to the large amount of text.  Split these messages into individual
lines, just as in the backtrace for .include files and .for loops.  This
unified backtrace makes the output more uniform.

make: in error message about conditionals, use single quotes

Single quotes are used less often in the conditionals themselves, which
leads to fewer confusions.

make: add more context information to error messages

In case of a parse error or evaluation error, print the variable value
in addition to the variable name, to see the effects of previous
expression modifiers.

In nested make calls, print the current directory at the bottom of a
stack trace, as that information is otherwise hard to get in a parallel
build spanning multiple directories.

make: provide more context information for parse/evaluate errors

tests/make: replace 'variable expression' with 'expression'

Each expression is based on a variable, there's no need for the
verbosity.  The wording in make's diagnostics will be changed in a
follow-up commit.

tests/make: force line-based diagnostics to be listed in the tests

This way, contradictions between the intended output and the actual
output are closer together and have a better chance of being spotted.

make: fix wrong expression evaluation in -dL mode

The modifier ':C' now only compiles the regular expression if the result
of the expression is actually needed.

Several other modifiers have the same bug of evaluating the expression
in cases where this is not needed.  It just doesn't show up because they
don't have any noticeable side effects, other than wasting CPU time.
This affects irrelevant conditions as well.

make: demonstrate wrong expression evaluation in -dL mode

make(1): remove wrong error message for indirect modifier in lint mode

make(1): use consistent indentation in variable assignments

Initial work by "pkglint -F *.mk", manually adjusted in a few places.

make(1): revert previous commit

It had accidentally reverted all the work from the past few days.

make(1): fix double-free bug in -DCLEANUP mode (since 2020-10-02)

The bug had been introduced with dir.c 1.155 on 2020-10-02 22:20:25.  In
that commit, openDirectories was replaced with a combination of a list
with a hash table, for more efficient lookup by name.

Upon cleanup, OpenDirs_Done is called, which in turn called
Dir_ClearPath.  Dir_ClearPath takes full ownership of the given list and
empties it.  This was no problem before since afterwards the list was
empty and calling Lst_Free just frees the remaining list pointer.

With OpenDirs, this list was combined with a hash table, and the hash
table contains the list nodes, assuming that the OpenDirs functions have
full ownership of both the list and the hash table.  This assumption was
generally correct, except for the one moment during cleanup where full
ownership of the list was passed to Dir_ClearPath, while the hash table
still contained pointers to the (now freed) list nodes.  This by itself
was not a problem since the hash table would be freed afterwards.  But
as part of Dir_ClearPath, OpenDirs_Remove was called, which looked up
the freed directory by name and now found the freed list node, trying to
free it again.  Boom.

Fixed by replacing the call to Dir_ClearPath with code that only frees
the directories, without giving up control over the list.

make(1): add test for variable modifiers without delimiter

make(1): fix wrong error for undefined variables in lint mode

make(1): add test for wrong error in lint mode for undefined variable

make(1): in lint mode, allow undefined variables in dependency lines

This is needed to get past the first few seconds in a src/build.sh run.

The nest obstacle is src/tools/Makefile.gnuhost:30, where the variable
MODULE is undefined even though that file says in line 3 that MODULE is
expected to be set.  It has been saying this since 2001, but since make
didn't have the corresponding check enabled, this didn't break the
build.

make(1): remove obsolete comments from tests

make(1): in lint mode, report undefined variables in conditions

make(1): in lint mode, improve error handling for undefined variables

It's a first step for improving the error message that make prints.

make(1): add tests for each debug option
