strerror_r-posix: Another fix, for HAVE_DECL_STRERROR_R on mingw
Commit 5ddd9d7 improved strerror_r on glibc systems (where
STRERROR_R_CHAR_P was defined twice with different values), but
missed mingw systems (where HAVE_DECL_STRERROR_R is now defined
twice with different values). Avoid the AC_CHECK_DECLS[_ONCE]
and AC_CHECK_FUNCS[_ONCE] m4 macros that call AC_DEFINE under the
hood, and instead limit our checks to just setting shell witnesses,
so that compilation on mingw doesn't trigger warnings (and mess up
subsequent tests that use -Werror) about a redefined C preprocessor
macro.
* m4/strerror_r.m4 (gl_FUNC_STRERROR_R, gl_FUNC_STRERROR_R_WORKS):

strerror_r-posix: Fix override of AC_FUNC_STRERROR_R
Requiring autoconf's AC_FUNC_STRERROR_R and then calling AC_DEFINE
ourselves leads to two insertions of #define STRERROR_R_CHAR_P
in confdefs.h, but with different values (at least on glibc). This
in turn sparks a gcc warning about redeclaring the macro, and kills
any subsequent tests that use -Werror (which now error because of
the conflicting define, whether or not the test used to error).
A better approach is to replace the autoconf macro with a version
of our own that doesn't probe anything, so that the AC_DEFINE is
reached exactly once.

parse-datetime: restrict debug output to input string
* lib/parse-datetime.y (parse_datetime2): If we parse
all of the input but determine it's invalid, ensure
we don't output the now invalid input pointer.
This issue was seen with `date -d 'now +1'`.

getprogname: port to systems with __argv (mingw, msvc)
* lib/getprogname.c (getprogname): Include "dirname.h" and use
last_component: more general than open coding it with hard-coded "/".
* lib/getprogname.h (getprogname): Prefer "char const *" consistently.
* modules/getprogname (Depends-on): Add dirname-lgpl.
(configure.ac): Check for __argv in <stdlib.h>.
* modules/getprogname-tests: New file.
* tests/test-getprogname.c: New file.
