Enhances some warnings as well as the sanitizers (Clang especially complained about it)
The `-f*` flags are to get better stack traces out of the sanitizers, as recommended
by Clang's docs: https://clang.llvm.org/docs/AddressSanitizer.html#usage
GCC's docs claim that these optimizations should not hinder the debugging
experience, and Clang's don't mention optimization flags at all.
Remove already-enabled warnings as pointed out by #969
Comments added to the CMakeLists because the Makefile format does not really allow them
"Plain" list also sorted alphabetically, the rest (somewhat) thematically
Simplify the mess that was option setting (2 redundant variables !?)
Move options to a separate file
Have "modules" own their options, and OPT only access them (less redundancy)
Simplify code, respect naming conventions better
- Make it work inside pipelines
- Add RGBFIX tests to the suite
- Be more flexible in accepted MBC names
- Add warnings for dangerous or nonsensical input params
- Improve man page
- POSIX sh actually does NOT support `+=`,
but Bash does even in compatibility mode
- `mawk` does not fully support POSIX EREs (regexes),
so work around its lack of brace support
Fixes building on Debian, apparently.
Build type no longer defaults to Release (!)
have separate options for extra warning flags and sanitizers
toss DEVELOP macro
Fix sanitizers with CMake while I'm at it :|
GCC with the -std=c11 defines __STRICT_ANSI__. DJGPP checks if
__STRICT_ANSI__ is defined and if so doesn't define some things
mandated by POSIX such as struct stat, PATH_MAX, and others.
The -std=gnu11 option does not define this macro, so use it instead.
_DEFAULT_SOURCE isn't needed as no GNU nor BSD-specific functions
are used. Remove it.
Fix the last two occurrences of incorrect format specifiers for standard
fixed-width integer types.
As 444 and 555 seem to be used for no apparent reason, use the more
conventional 644 and 755.
/man is typically unused or a symlink to /share/man now, so just use
/share/man.

Note: I wanted to enable `-Og` on `develop`, but this generated warnings
(thus, errors) that aren't in `-O0`. Needs further investigation, but
annoyingly some of those are within `extern/` code, thus requiring
different flags, which AFAIK is only possible (sanely) with GNU Make.
Adds links to argument descriptions in synopsis
Adds links to man pages in the set (not to external ones)
Removes artifact from the way long opts are encoded
Makes description blurb inline, consistently with terminal output
