Update Gnulib to the latest git version

This patch allows us to remove a workaround in common-defs.h due to the gnulib fix in: https://lists.gnu.org/archive/html/bug-gnulib/2019-11/msg00024.html All of GDB's local Gnulib patches were already fixed upstream per their descriptions, so this patch removes them all. The problem listed here: https://sourceware.org/ml/gdb-patches/2019-08/msg00553.html was probably partially fixed by moving gnulib to the toplevel; for the remainder, I am setting MAKEOVERRIDES to empty in gnulib/Makefile.am. See also the comment there (it fixes an issue with compilers that don't use C99/C11 by default such as GCC 4.8.5, the default on Centos 7). gdb/ChangeLog: 2019-12-16 Christian Biesinger <cbiesinger@google.com> * gdbsupport/common-defs.h: Remove workaround for a gnulib bug (we no longer need to include time.h before pathmax.h) gnulib/ChangeLog: 2019-12-16 Christian Biesinger <cbiesinger@google.com> * Makefile.am: Set MAKEOVERRIDES. * Makefile.in: Regenerate. * aclocal.m4: Regenerate. * config.in: Regenerate. * configure: Regenerate. * import/Makefile.am: Update. * import/Makefile.in: Regenerate. * import/_Noreturn.h: New file. * import/alloca.c (i00afunc): Update. * import/alloca.in.h (if): Update. * import/arg-nonnull.h: Rename from import/extra/snippet/arg-nonnull.h. * import/arpa_inet.in.h (if): Update. * import/assure.h: Update. * import/at-func.c: Update. * import/basename-lgpl.c: Update. * import/canonicalize-lgpl.c (if): Update. * import/c++defs.h: Rename from import/extra/snippet/c++defs.h. * import/cdefs.h: New file. * import/chdir-long.c: Update. * import/chdir-long.h: Update. * import/cloexec.c: Update. * import/cloexec.h: Update. * import/close.c: Update. * import/closedir.c: Update. * import/config.charset: Remove. * import/dirent-private.h: Update. * import/dirent.in.h: Update. * import/dirfd.c: Update. * import/dirname-lgpl.c: Update. * import/dirname.h (base_name): Update. * import/dosname.h (if): Update. * import/dup-safer-flag.c: New file. * import/dup-safer.c: Update. * import/dup.c: Update. * import/dup2.c (if): Update.
