rillig | lint: in declarations, replace tab with space
Previously, in some cases, the keywords 'const' or 'struct' were
followed by a tab, which doesn't make sense.
No functional change.

rillig | lint: remove custom memory allocator
Besides adding complexity, the custom memory allocator didn't invalidate
freed memory, which made it harder to find possible use-after-free bugs.
|

rillig | lint: use __RCSID in lint mode as well
Since 1995-10-02, lint supports __asm statements and __asm modifiers.
No binary change.

rillig | lint: remove WARNS=3, falling back to the default WARNS=5
It's strange that GCC does not warn about the nonliteral format strings
in lint1/err.c, lint2/msg.c and lint2/read.c, despite -Wformat=2, but
Clang does.

No functional change.

rillig | lint: in malloc calls, use 'sizeof *ptr' instead of 'sizeof(type)'
No functional change.
|
| 1.13 |
| 16-Jan-2021 |
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: update usage for lint1 and lint2
(Forgotten in the previous commit.)

rillig | lint: add new check for strict bool mode
In strict bool mode, bool is considered incompatible with all other
scalar types, just as in Java, C#, Pascal.
The controlling expressions in if statements, while loops, for loops and
the '?:' operator must be of type bool. The logical operators work on
bool instead of int, the bitwise operators accept both integer and bool.
The arithmetic operators don't accept bool.
Since <stdbool.h> implements bool using C preprocessor macros instead of
predefining the identifiers "true" and "false", the integer constants 0
and 1 may be used in all contexts that require a bool expression.
Except from these, no implicit conversion between bool and scalar types
is allowed.
See usr.bin/tests/xlint/lint1/d_c99_bool_strict.c for more details.
The command line option -T has been chosen because all obvious choices
(-b or -B for bool, -s or -S for strict) are already in use. The -T may
stand for "types are checked strictly".
The default behavior of lint doesn't change. The strict bool check is
purely optional.
An example program for strict bool mode is usr.bin/make, which has been
using explicit comparisons such as p != NULL, ch != '\0' or n > 0 in
most places for a long time now, even before the refactoring in 2020.

jmc | Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')
Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

lukem | cleanup (prior to more adding more features):
- convert to ANSI KNF
- remove trailing whitespace
- translate some comments from german into english
code compiles and runs clean, and tested by running "make lint" against
xlint source using previous and this lint produces same results.
