gcalloc: fix: do not abort on calloc(0, x) or calloc(x, 0) returning NULL
Commit
43a37bedd934bde50a6441766b85dfc9648abda9 added a `calloc` wrapper but
mistakenly did not account for it being valid for `calloc` to return `NULL` when
the input arguments are 0. This is unlikely to have caused a problem with Glibc
whose allocator typically returns non-null pointers even for 0 allocations.
However assuming a 0 allocation may return a null pointer is more portable.

Matthew Fernandez [Tue, 20 Jul 2021 03:25:16 +0000 (20:25 -0700)]
replace mkdefs-generated gdefs.h with X macros
Prior to this commit, the gdefs.h header was generated by a C program, mkdefs.c.
There were a number of issues with this approach:
1. The CMake build system was assuming the compiler to build mkdefs.c and the
compiler to build Graphviz itself were the same. This is not necessarily
true when cross-compiling.
2. Generation under MSBuild seems to have been impractical, so the generated
header was checked in to the repository under windows/include/gvpr/gdefs.h,
somewhat defeating the purpose of making it generated.
3. The CMake build system seems to not have been setup to correctly compile
mkdefs.c under all circumstances (see #2101).
This change removes any reliance on a host C compiler and instead uses a series
of X macros¹ to achieve the same effect. The values of all generated constants
and the content of generated structures is intended to be unchanged, though some
#defines have been altered to enums. In these cases, there was no advantage to
using a macro and multiple advantages to not using a macro.
This change is affecting a shipped header (gdefs.h) and also removes it from the
list of shipped headers. Installing it appears to have been a mistake as there
is no easy way for end users to use it. The header, fully expanded, still relies
on further expansion of macros that are only defined in expr.h, a header that is
not shipped.
Closes #2101.

lib/expr: use RSH as a constant for >> instead of RS
A couple of places in the code base are dodging an `RS` symbol apparently
introduced by an HPPA header. It is simpler to just use a symbol that does not
collide at all.

Initialize nPasses in aspect_t struct in SetAspect
In dotLayout, nPasses is decremented in a while loop. Since it may be
uninitialized, this triggers clang's UndefinedBehaviorSanitizer:
signed-integer-overflow. While behavior does not change because the loop also
checks nextIter, which is initialized, this change fixes the sanitizer error.

rewrite edgepaint command line parsing using getopt_long

Surprisingly this is configured but never used. Instead all code accesses the

rewrite edgepaint command line parsing using getopt_long
This change makes edgepaint command line parsing code more standard and robust.
It now rejects invalid arguments and takes more standard GNU-style double dash
prefixed options. Note that the old style single dash prefixed options are also
still accepted for compatibility purposes. Closes #1971.
