glibc/sysdeps/nptl/malloc-machine.h
Joseph Myers 02d55fe04e Rename bits/libc-tsd.h to libc-tsd.h (bug 14912).
It was noted in
<https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the
bits/*.h naming scheme should only be used for installed headers.
This patch renames bits/libc-tsd.h to plain libc-tsd.h to follow that
convention.

Tested for x86_64 (testing, and that installed stripped shared
libraries are unchanged by the patch).

	[BZ #14912]
	* bits/libc-tsd.h: Move to ...
	* sysdeps/generic/libc-tsd.h: ...here.
	(_GENERIC_BITS_LIBC_TSD_H): Rename macro to _GENERIC_LIBC_TSD_H.
	* sysdeps/mach/hurd/bits/libc-tsd.h: Move to ...
	* sysdeps/mach/hurd/libc-tsd.h: ...here.
	(_BITS_LIBC_TSD_H): Rename macro to _LIBC_TSD_H.
	* include/ctype.h: Include <libc-tsd.h> instead of
	<bits/libc-tsd.h>.
	* include/rpc/rpc.h: Likewise.
	* locale/localeinfo.h: Likewise.
	* sunrpc/rpc_thread.c: Likewise.
	* sysdeps/mach/hurd/malloc-machine.h: Likewise.
	* sysdeps/nptl/malloc-machine.h: Likewise.
