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.
