glib2: Update to 2.56.0

Closes: https://trac.macports.org/ticket/56081

Also, patch configure.ac, not configure. The reason why we were patching
configure was that patching configure.ac would have required running
autoreconf, and that would have required pkg-config, and at the time,
pkg-config depended on glib2, and MacPorts cannot accommodate circular
dependencies. pkg-config has included its own private copy of glib2
since f0e3b8c, so this reason no
longer applies.

We have been maintaining a large configure patch which needs to be
tediously regenerated from the configure.ac patch whenever glib2 is
updated. That effort is saved by being able to use the configure.ac
patch directly.

The Portfile is also simplified by allowing pkg-config to find the
libraries of the dependencies, rather than having to specify each of
them manually.

Reverts 847ba02.

See: https://trac.macports.org/ticket/55577

Also, add SIZEOF_SSIZE_T handling to config.h.ed. This should have been
done in 2eb6602 when similar patching
was added to the configure script. Add a comment to the patch to remind
the maintainer to update config.h.ed too.

Also, no longer undefine AC_APPLE_UNIVERSAL_BUILD in config.h. It's
unclear why we were ever doing this. config.h is only used at build
time. The only thing AC_APPLE_UNIVERSAL_BUILD currently does is ensure
WORDS_BIGENDIAN is defined correctly. glib doesn't use WORDS_BIGENDIAN;
it uses its own G_BYTE_ORDER, G_BIG_ENDIAN and G_LITTLE_ENDIAN. Maybe
AC_APPLE_UNIVERSAL_BUILD used to do something more objectionable.
