Gnulib integration

Applied the following command:

  git submodule add git://git.sv.gnu.org/gnulib.git

This added gnulib in .git/index and created an empty `gnulib'
directory.  This directory contains all the gnulib code, but is not
distributed. gnulib m4 dir are now in `gnulib_m4', while gnulib .c
files are located in `lib'.  `gnulib_m4' and `lib' are generated and
distributed.

* .gitsubmodules: new file.
* src/libs/gnulib: removed.

Minimal Automake support.  Makefile in non-recursive style.

Removed old build system Makefile.*.  Removed various files that are
now generated by the bootstrap script: `configure',
`src/include/config.hin', various helper scripts (`config.guess',
`config.rpath' etc...) that are now installed by in `build-aux'.
Added the minimal code in Makefile.am to build the gnulib.

* Makefile.am: new file (moved and adapted from Makefile.in).
* acinclude.m4: new file (moved from aclocal.m4, which is now generated).
* INSTALL.extra: new file (moved from the original INSTALL file, which
  is now a symlink to gnulib/doc/INSTALL).
* THANKS, AUTHORS: new empty files.
* TESTS: new file to sum up the tests that were done for the Automake
  migration.
