Import the "signal-h" module from gnulib
This gives us a signal.h replacement that makes sure the sighandler_t typedef (a GNU extension) is always available. A follow up patch will make use of this. gdb/ChangeLog: 2015-08-27 Pedro Alves <palves@redhat.com> * gnulib/update-gnulib.sh (IMPORTED_GNULIB_MODULES): Add signal-h. * gnulib/aclocal.m4: Renegerate. * gnulib/config.in: Renegerate. * gnulib/configure: Renegerate. * gnulib/import/Makefile.am: Update. * gnulib/import/Makefile.in: Regenerate. * gnulib/import/m4/gnulib-cache.m4: Update. * gnulib/import/m4/gnulib-comp.m4: Update. * gnulib/import/m4/signal_h.m4: New file. * gnulib/import/signal.in.h: New file.
