lint: add wrapper for <ctype.h> functions, for strict bool mode
When using the Clang preprocessor (with MKLLVM=yes), the preprocessor
output does not indicate which tokens come from a system header and
which tokens come from the user code. Lint's strict bool mode relies on
this information to treat the character classification functions from
<ctype.h> as if their return type were bool instead of int.
These wrapper functions are only used when their argument is indeed a
'char', but not when the argument might be 'EOF or representable as an
unsigned char', such as when reading a byte from the input.

rillig | lint: in declarations, replace tab with space

rillig | lint: prevent invalid memory access when checking an expression
In check_expr_misc, the left and right operands of an expression were
accessed even in the case of CON (constant), STRING (string literal) and
NAME (identifier), which led to invalid values in pointer variables.
These invalid values were not used though, but technically they invoked
undefined behavior.
Precede each access to the operands with a check that the expression
indeed has operands, except in those cases where the operand is known to
have operands by only looking at the code of the current function.

rillig | lint: warn about pointer casts between different kinds of types
Pointer casts from an integer type to a floating-point type and vice
versa get a 'maybe troublesome' warning now. The previous assumption
that all types of the same bit-size are convertible may have been valid
from a technical point of view, but still such code should get more
attention.
The rules for struct and union types could be made more fine-grained
later, if the need arises. To suppress this warning, it's always
possible to cast to an intermediate 'void *'.

rillig | lint: drop compatibility with C90
Since tools/README 1.5 from 2022-02-03, the tools no longer need to be
compatible with C90, they may now use C99 features. Lint had used
<stdbool.h> and snprintf already.
No functional change.

rillig | lint: enter full C90 compatibility mode
The C99 comment in tree.c:3468 has been there since 2017-03-06, without
anyone complaining that their compiler would not handle it.
Strangely, running GCC 10.3.0 in '-std=c90' mode does not complain about
declarations after statements, '-Wdeclaration-after-statement' is needed
separately.
No functional change.

same.

rillig | lint: use 'unsigned int' for bit-size of types
Lint does not need to support any types larger than 256 MB since they
don't occur in practice. Practically, such large types have never been
supported at all since the function type_size_in_bits used int for the
internal calculations, resulting in overflows.

rillig | lint: use distinct struct tags for type_t in lint1 and lint2
Having two similar but still different definitions of 'struct type' is
unnecessarily confusing. Exchange this confusion for 8 lines of
straight-forward preprocessing code.
|

| 28-Feb-2021 |
rillig | lint: rename members and access macros of the basic types
Having the measurement unit in the variable name prevents accidental
confusion between bits and bytes, especially since usually the word
'size' means the size in bytes, while 'width' means the size in bits, at
least for integer types.
No functional change.

rillig | 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.

rillig | lint: rename type classification macros
The previous names tspec_is_int and tspec_is_uint were confusing because
there are actually tspec_t constants called INT and UINT, these
classification macros return true for other integer types as well,
though.
While here, remove the prefix "tspec_" from these macros. It wasn't as
helpful as intended, in many cases it was obviously redundant, when it
was called as tspec_is_integer(tn->tn_type->t_tspec).
No functional change.

Since type_t is different between lint1.h and lint2.h include the
appropriate file depending on the pass. Make the argument mismatch
error print the type names of the types involved. Now that we have
a tyname() function we can fix the rest of the pass2 warnings to be
more explanatory, but not now.

lukem | Overhaul how `build.sh tools' are used:
* Rename "config.h" to "nbtool_config.h" and
HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
This makes in more obvious in the source when we're using
tools/compat/config.h versus "standard autoconf" config.h
* Consistently move the inclusion of nbtool_config.h to before
<sys/cdefs.h> so that the former can provide __RCSID() (et al),
and there's no need to protect those macros any more.
These changes should make it easier to "tool-ify" a program by adding:
#if HAVE_NBTOOL_CONFIG_H
#include "nbtool_config.h"
#endif
to the top of the source files (for the general case).

* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.
