* glib.h, galloca.h, garray.h, gasyncqueue.h, gbacktrace.h,
gcache.h, gcompletion.h, gconvert.h, gdataset.h, gdate.h, ghash.h,
ghook.h, giochannel.h, glist.h , gmacros.h, gmain.h, gmem.h,
gmessages.h, gnode.h, gprimes.h, gquark.h, gqueue.h, grand.h,
grel.h, gscanner.h, gslist.h, gstrfuncs.h, gstring.h, gthread.h,
gthreadpool.h, gtimer.h, gtree.h, gtypes.h, gutils.h: Split glib.h
into many header files mostly according to the resp. *.c-files.
* gmacros.h: Added G_BEGIN_DECLS and G_END_DECLS to mean: 'in case
of C++: extern "C" { ... }' analogous to glibc __BEGIN_DECLS and
__END_DECLS.
* configure.in, gerror.h, gfileutils.h, gshell.h, gspawn.h,
gunicode.h, : Changed guard-macro names to something more
consistent.
* configure.in, *.h: Use G_BEGIN_DECLS and G_END_DECLS.
