lint: add additional queries that are not enabled by default

In the last 18 months, several lint warnings have been made adjusted to
allow common usage patterns.  For example, lint no longer warns about a
constant condition in the statement 'do { ... } while (false)' (message
161), as this pattern is well-known in statement-like macros, making it
unlikely that the 'false' is a mistake.  Another example is casts
between unequal pointer types (message 247) for a few well-known
patterns that are unlikely to be bugs.

Occasionally, it is useful to query the code for patterns or events that
would not justify a warning.  These patterns are modeled as predefined
queries that can be selected individually, in addition to and
independently of the existing warnings and errors.

New queries can be added as needed, in the same way as new warnings.
Queries that are deemed no longer used can be deactivated in the same
way as warnings that are no longer used.

As long as none of the queries is enabled, they produce a minimal
overhead of querying a single global variable.  Computations that are
more expensive than a few machine instructions should be guarded by
any_query_enabled.

lint: fix check for function calls in strict bool mode

Previously, if a function call occurred in the controlling expression,
its return type could be any scalar, not just bool.  This was against
the goal of strict bool mode, which makes bool a separate and
incompabile type to all other types.  For example, it would allow
controlling expressions like 'strcmp(a, b)' without the usual '!= 0',
but only if at least one of 'a' and 'b' came from a macro definition
from a system header.

The fix is that the decision of whether the type of the controlling
expression may be scalar is no longer based on the operand types but on
the main operator of the controlling expression.

separately.

lint: remove hash value from symbol buffer

lint: improve support for __int128_t and __uint128_t

For the .ln files, I chose the letter 'J' to represent the 128-bit
integer types since it is close to 'I' for int.  The naming of 'L' for
'long' is obvious, but 'Q' for 64-bit integers is a quad-16-bit word,
which is an unusual measurement unit nowadays.  One benefit of choosing
'J' is that the next letter, 'K' can then be used for 256-bit integer
types.

Support for 128-bit integer types is still very basic.  Plus, it is only
supported on LP64 platforms, which means that lint cannot be
cross-compiled to check for an LP64 platform while running on an ILP32
platform.

lint: rename val_t.v_unsigned to avoid confusion

The name v_unsigned suggested that the value would be interpreted as
unsigned, which was wrong.  Whether a value is signed or unsigned is
decided by v_tspec instead.

Revert the previous commit for boolen constants since their value is
already interpreted as unsigned, and there is no need for any warning
about differences between traditional C and ANSI C since the _Bool type
has only been added ten years later in C99.

The code for printing a tree node was also confused by this struct
member, even with its old name v_ansiu.  That code will be fixed in a
follow-up commit.

lint: rename val_t.v_ansiu to v_unsigned

When lint was written in 1995, traditional C was still nearby since C90
had been around for only 5 years.  26 years later, almost all code
adheres to C90 or even C99 or C11, therefore "C90 or later" can safely
be assumed as the default.

lint: replace array access with function calls

First and foremost, the test d_c99_complex_split accessed the array
qlmasks out-of-bounds, with an index of 128 for the type 'double
_Complex'.  This invoked undefined behavior since the maximum allowed
index was 64.

Replacing the raw array accesses with function calls allows for bounds
checks to catch these errors early.

Determining the value bits for a 'double _Complex' does not make sense
at all since it is not an integer type.  This means that lint didn't
handle these types correctly for several years.  Support for int128_t
has been added in inittyp.c 1.12 from 2018-09-07, support for _Complex
has been added in inittyp.c 1.9 from 2008-04-26.

Determining the value bits for an int128_t would make sense, but the
unit tests don't contain examples for this type since at the moment all
unit tests must produce the same results on 32-bit and 64-bit platforms,
and the 32-bit platforms don't support int128_t.

lint: in strict bool mode, integer constants do not have type bool

Previously, lint1 allowed integer constants such as 0 and 1 to be used
as bool constants.  This was only half-baked since after fixing all
error messages from that strict mode, there may still be integer
literals in the code that should be replaced with true or false.  This
would stop a migration from int to bool in the middle, leaving
inconsistent code around.

To find the remaining type inconsistencies, treat integers and bool as
completely incompatible, even for compile time constants.

lint: replace 0 and 1 with false and true, where appropriate

Change in behavior: Passing the option -h exactly 4294967296 times or
any multiple thereof is no longer equivalent to passing it never at all,
it is now equivalent to passing it once.  See main2.c, hflag++ for the
actual change.

Other than that, no functional change intended.

A very large portion of the code already conformed to the requirements
of the strict bool mode.  The only missing thing was using the constant
literals false and true instead of 0 and 1.  For sure there are some
integer literals left that can be converted.  For now, all literals that
appeared in the form " = 0" or " = 1" have been replaced.

lint: rename cstk to cstmt

Most of the code that deals with control statements is only interested

Therefore, emphasize that part in the variable name.

The member c_next was confusing since the "direction" of this "next
element" was ambiguous.  In a sequence of if statements, the "next"
element could have equally been the following one, not the surrounding
one.
