* resolv/resolv.h (_res): Define macro unconditionally.

[! _LIBC_REENTRANT] (_res): Move this conditional decl to ...
	* include/resolv.h: ... here.
	[USE_TLS && HAVE___THREAD] (_res): #undef it and declare
	as a __thread variable.
	* resolv/res_libc.c [USE_TLS && HAVE___THREAD] (_res): Define it as
	a __thread variable instead of a global.
	* resolv/res_data.c [_LIBC]: Don't #undef _res.

	* include/errno.h: Include <tls.h> to make sure USE_TLS defined by the
	time we test it.

	* intl/loadmsgcat.c [__GNUC__]: #undef alloca before defining it.

	* malloc/malloc.c [_LIBC]: Include <string.h> instead of using local
	decls of memset and memcpy.

	* sysdeps/generic/sysdep.h (END): Conditionalize on [__ASSEMBLER__].
	* sysdeps/unix/sysv/linux/i386/sysdep.h (L): Likewise.

	* elf/dl-load.c (_dl_map_object_from_fd): Comment fix.

	* sysdeps/generic/bits/libc-tsd.h [USE_TLS && HAVE___THREAD]
	(__libc_tsd_define): Define using __thread.

	* sunrpc/rpc_thread.c: Use __libc_tsd_define.
	(__rpc_thread_variables): Use __libc_tsd_get.
	(__rpc_thread_destroy): Use __libc_tsd_get instead of calling
	__rpc_thread_variables, which might allocate what we're about to free.

	* inet/herrno.c [USE_TLS && HAVE___THREAD] (h_errno): Define as a
	thread-local variable.
	* resolv/netdb.h (h_errno): Define macro unconditionally.
	[_LIBC] (__set_h_errno): Macro moved to ...
	* include/netdb.h: ... here.
	[USE_TLS && HAVE___THREAD] (h_errno): Declare __thread variable.
	[USE_TLS && HAVE___THREAD] (__set_h_errno): Define using that.
	[! _LIBC_REENTRANT]: #undef h_errno here.

	* include/errno.h: Protect from multiple inclusion.

	* misc/sys/select.h (__NFDBITS, __FDELT, __FDMASK): #undef these
	before defining them, since Linux's <linux/posix_types.h> might have
	defined them.
