Tim-Philipp Müller 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

README 

The files

 asnprintf.c
 printf-args.c
 printf-args.h
 printf-parse.c
 printf-parse.h
 vasnprintf.c
 vasnprintf.h

are taken from the vasnprintf module of the GNUlib package, which can
be found at:

 http://www.gnu.org/software/gnulib/

All files have been modified to include g-gnulib.h.

vasnprintf.c has also been modified to include support for long long
printing if the system printf doesn't. This code is protected by
#ifndef HAVE_LONG_LONG_FORMAT.

Code has been added to printf-args.[ch], printf-parse.c and vasnprintf.c
to support printing of __int64 values with the I64 format modifier. This
is protected by #ifdef HAVE_INT64_AND_I64.

The files

 printf.h
 printf.c
 g-gnulib.h

have been written by me. printf.[hc] contain implementations of the
remaining functions in the printf family based on vasnprintf.
g-gnulib.h is included by all source files in order to move all
exported functions to the _g_gnulib namespace, replace malloc by
g_malloc and make sure that snprintf is only used if it implements
C99 return value semantics.

GStreamer modifications

This was imported from GLib's gnulib subdirectory.

g-gnulib.h and _g_gnulib namespace has been changed to gst-printf.h and
__gst_printf namespace for GStreamer. Also #define HAVE_SNPRINTF 0 has
been changed to #undef HAVE_SNPRINTF, and HAVE_ALLOCA has been replaced
by an #if defined(alloca) || defined(GLIB_HAVE_ALLOCA_H)

printf-extension.[ch] were added to provide support for custom pointer
arguments (e.g. caps, events, etc.)

Files have also been indented with gst-indent, so this is basically a
permanent fork and any patches will have to be merged manually.
