Remove stray *_internal aliases (bug 14132).

This patch removes some stray (unused) *_internal aliases, and
function prototypes with no corresponding definitions at all, at least
some of which were missed in previous INTDEF / INTUSE removal.

Not removed in this patch: __canonicalize_directory_name_internal,
noticed in the course of preparing this patch, isn't an alias, but an
actual function in sysdeps/mach/hurd/getcwd.c - apparently unused,
however.

Tested for x86_64 that installed stripped shared libraries are
unchanged by this patch.

	[BZ #14132]
	* include/wctype.h [!_ISOMAC] (__iswalpha_l_internal): Remove
	declaration.
	[!_ISOMAC] (__iswdigit_l_internal): Likewise.
	[!_ISOMAC] (__iswspace_l_internal): Likewise.
	[!_ISOMAC] (__iswxdigit_l_internal): Likewise.
	[!_ISOMAC] (__iswctype_internal): Likewise.
	* stdio-common/siglist.c (_sys_siglist_internal): Remove alias.
	* sysdeps/unix/syscalls.list (chown): Remove __chown_internal
	alias.
	(fcntl): Remove __fcntl_internal alias.
	* sysdeps/unix/sysv/linux/hppa/syscalls.list (connect): Remove
	__connect_internal alias.
	* sysdeps/unix/sysv/linux/sparc/sparc64/syscalls.list (connect):
	Likewise.
