55f9406f30 printf: On MSVC, also define HAVE_STDINT_H_WITH_UINTMAX
MSVC provides stdint.h but not inttypes.h, and we need to include stdint.h to
get intmax_t

3da3e8df3e printf: handle unsigned modifier for long long
Otherwise, an unsigned integer will be displayed as a signed one if we
use internal print, ie HAVE_LONG_LONG_FORMAT is not defined.

e8a9f7acdf printf: fix handling of old printf extension specifiers for ABI compatibility
Fixes abort when the old specifiers are used. Fix up the conversion
specifier, it would get overwritten with 'c' below to the extension
format char, which then later is unhandled, leading to the abort.
Also fix up and enable unit test for this.

91c42b9380 printf: use sprintf() to work around glibc complaining about %n in a writable format string
Don't use snprintf(), but use sprintf instead and do our own
length calculations, because glibc may complain about us passing
%n in a format string if the string is in writable memory, and
here the format string is always in writable memory since we
construct it on the fly. This happens if glibc has been compiled
with _FORTIFY_SOURCE=2, which seems to be the case on some
distros/systems). On the upside, we now use the sprintf code path
on all systems which should be better from a maintenance point
of view.

3c1d9c6d41 printf: fix alloca use for windows with mingw32
Don't use just GLIB_HAVE_ALLOCA_H to check if alloca is available,
that's just for the header. GLib may define alloca for us otherwise
too irrespective of GLIB_HAVE_ALLOCA_H.

Fixes compiler warning with mingw32:
gst/printf/vasnprintf.c:73:0: warning: "alloca" redefined

ff292d530c printf: enable and fix compiler warnings
But suppress -Wformat-nonliteral warnings since sprintf
is used with a runtime-generated format string in our
vasnprintf implementation.

fe7f7135e0 printf: add infrastructure for pointer extensions hook
Does not do anything yet. On a sidenote, we can't just use
%p\001 or so to signal the extension because g-i complains
about an invalid ascii character then, so have to resort to
something more elaborate, such as %p\aA etc.

8fc876f09f printf: add our own printf implementation for debug logging
We will add support for our own printf modifiers, so we can
get nice debug log output on all operating systems irrespective
of the specific libc version used.
