Simplify Emacs part of pthread_sigmask support.

* Makefile.in (GNULIB_TOOL_FLAGS): Do not avoid sigprocmask.
* configure.in (AC_TYPE_UID_T): New dummy macro.
Configure gnulib after adjusting LIBS,
so that gnulib can assume the libraries in LIBS.
* lib/pthread_sigmask.c, lib/sigprocmask.c, m4/signalblocking.m4:
New files, automatically imported from gnulib.
* lib/gnulib.mk, m4/gl-comp.m4: Regenerate.
* src/Makefile.in (LIB_PTHREAD_SIGMASK): New macro.
(LIBES): Use it.

         Add gnulib support for pthread_sigmask (Bug#9010).
         * Makefile.in (GNULIB_MODULES): Add pthread_sigmask.
-        (GNULIB_TOOL_FLAGS): Avoid sigprocmask.  Emacs does its own
-        implementation of 'sigprocmask' on Windows, and it assumes
-        'sigprocmask' on non-Windows hosts, so it doesn't need the
-        sigprocmask module.
+        * configure.in (AC_TYPE_UID_T): New dummy macro.
+        Configure gnulib after adjusting LIBS,
+        so that gnulib can assume the libraries in LIBS.
         * lib/signal.in.h, m4/pthread_sigmask.m4, m4/signal_h.m4:
+        * lib/pthread_sigprocmask.c, lib/sigprocmask.c, m4/signalblocking.m4:
         New files, automatically imported from gnulib.
         * lib/gnulib.mk, m4/gl-comp.m4: Automatically-imported update
         due to the above changes.
         * .bzrignore: Add lib/signal.h.
+        * src/Makefile.in (LIB_PTHREAD_SIGMASK): New macro.
+        (LIBES): Use it.
