libiberty: documentation markup and order fixes.

libiberty/:
	* splay-tree.c: Escape wrapping newlines in texinfo markup
	with '@', to fix function declaration output rendering.
	* gather-docs: Relax and improve macro name matching to actually
	match all current names and to allow input line wrapping.
	* bsearch.c, concat.c, crc32.c, fnmatch.txh, fopen_unlocked.c,
	hashtab.c, insque.c, make-relative-prefix.c, memchr.c, memcmp.c,
	memcpy.c, memmem.c, memmove.c, mempcpy.c, memset.c,
	pexecute.txh, random.c, setenv.c, setproctitle.c,
	simple-object.txh, snprintf.c, stpncpy.c, strncmp.c, strtod.c,
	strtol.c, vasprintf.c, vprintf.c, vsnprintf.c, xmemdup.c:
	Wrap long texinfo input lines.
	* functions.texi: Regenerate.
