Upgrade Gnulib files to 20190105.
It's much easier to maintain GRUB's use of portability support files
from Gnulib when the process is automatic and driven by a single
configuration file, rather than by maintainers occasionally running
gnulib-tool and committing the result. Removing these
automatically-copied files from revision control also removes the
temptation to hack the output in ways that are difficult for future
maintainers to follow. Gnulib includes a "bootstrap" program which is
designed for this.
The canonical way to bootstrap GRUB from revision control is now
"./bootstrap", but "./autogen.sh" is still useful if you just want to
generate the GRUB-specific parts of the build system.
GRUB now requires Autoconf >= 2.63 and Automake >= 1.11, in line with
Gnulib.
Gnulib source code is now placed in grub-core/lib/gnulib/ (which should
not be edited directly), and GRUB's patches are in
grub-core/lib/gnulib-patches/. I've added a few notes to the developer
manual on how to maintain this.

libgcrypt-grub shouldn't be modified directly anyway. With this patch
tarball without contrib can be unpacked on FAT and stay usable for
out-of-tree compile on full POSIX FS (compile on FAT not tested).
* autogen.sh: Create symlinks to ${GRUB_CONTRIB} if necessary to
avoid confusing Automake. Run autogen only twice, once for the top
level and once for grub-core. Add Makefile.util.def and
Makefile.core.def from extra modules to the appropriate autogen
invocations. If Makefile.common exists in an extra module, include
it in both Makefile.util.am and grub-core/Makefile.core.am;
similarly, include any Makefile.util.common file in Makefile.util.am
and any Makefile.core.common file in grub-core/Makefile.core.am.
* conf/Makefile.common ($(top_srcdir)/grub-core/Makefile.core.am):
Depend on $(top_srcdir)/grub-core/Makefile.gcry.def.
($(top_srcdir)/grub-core/Makefile.gcry.def): Remove.
* grub-core/Makefile.am: Remove inclusion of Makefile.gcry.am.
* gentpl.py (gvar_add): Turn GVARS into a set.
(global_variable_initializers): Sort global variables on output.
(vars_init): New function.
(first_time): Likewise.
(library): Ensure that non-global variable initialisations are
emitted before the first time we emit code for a library block.
Append to variables rather than setting them. Only emit
noinst_LIBRARIES, BUILT_SOURCES, and CLEANFILES the first time for
each conditional path.
(program): installdir() emits an Autogen macro, so must be passed to
var_add rather than gvar_add.
(data): Likewise.
(script): Likewise.
(rules): New function, centralising handling for different target
types. Set up Guile association lists for first_time and vars_init,
and send most output to a diversion so that variable initialisations
can be emitted first.
(module_rules): Use new rules function.
(kernel_rules): Likewise.
(image_rules): Likewise.
(library_rules): Likewise.
(program_rules): Likewise.
(script_rules): Likewise.
(data_rules): Likewise.
* configure.ac: Add AC_PROG_LN_S, for the benefit of ntldr-img.
* .bzrignore: Add contrib and grub-core/contrib. Remove
grub-core/Makefile.gcry.am.
* aclocal.m4: Move from here ...
* acinclude.m4: ... to here.
* autogen.sh: Add call to `aclocal'.
* configure.ac: Add AM_INIT_AUTOMAKE() after AC_INIT() call.
This prevents autoheader from being rerun by make if somebody changes
configure.ac or aclocal.m4 and runs autogen.sh.
