Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (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-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #14912] * bits/libc-lock.h: Move to ... * sysdeps/generic/libc-lock.h: ...here. (_BITS_LIBC_LOCK_H): Rename macro to _LIBC_LOCK_H. * sysdeps/mach/hurd/bits/libc-lock.h: Move to ... * sysdeps/mach/hurd/libc-lock.h: ...here. (_BITS_LIBC_LOCK_H): Rename macro to _LIBC_LOCK_H.
