collapse N copies of xmalloc

[Zack Weinberg]

All the genfoo programs have a private copy of xmalloc.  Now we have
gensupport.c, we can collapse all those private copies into there.
The exceptions are gencheck.c and gengenrtl.c, which are not really
"genfoo programs" in the sense of reading md files.  It's not as good
as getting them linked with libiberty, but it's an improvement.

"make clean; make LANGUAGES=c" completes successfully on i386-linux.

	* gensupport.c (xmalloc, xrealloc, xstrdup): Provide.
	* genattr.c, genattrtab.c, gencodes.c, genconfig.c, genemit.c,
	genextract.c, genflags.c, genopinit.c, genoutput.c, genpeep.c,
	genrecog.c: Remove private copies of xmalloc, xrealloc, and
	xstrdup.
