pathconf (sysdeps/unix/sysv/linux/pathconf.c) uses basename.  But
pathconf is in POSIX back to 1990 while basename is only reserved with
external linkage in those standards including XPG functions.  This
patch fixes this namespace issue in the usual way, renaming basename
to __basename and making it into a weak alias.

Tested for x86_64 and x86 (testsuite, and that disassembly of
installed shared libraries is unchanged by the patch).

	[BZ #18444]
	* string/basename.c (basename): Rename to __basename and define as
	weak alias of __basename.  Use libc_hidden_weak.
	* include/string.h (__basename): Declare.  Use libc_hidden_proto.
	* sysdeps/unix/sysv/linux/pathconf.c (distinguish_extX): Call
	__basename instead of basename.
	* conform/Makefile (test-xfail-POSIX2008/unistd.h/linknamespace):
	Remove variable.
	(test-xfail-XOPEN2K8/unistd.h/linknamespace): Likewise.

Clean up string functions that do not have a version in gnulib on
the assumption that glibc is the canonical upstream copy of this
code. basename has a copy in gnulib but it is largely written to
handle Windows paths so merging it is not really viable. The changes
mostly consist of switching to ANSI function prototypes and removing
unused includes.

As many of these functions do not get built in a typical build due
to architecture optimized versions being used instead I built these
by hand to verify there were no build warnings and the code was
identical.
