ALL: updated m4 distribution format

The markup format distributed by the Autoconf Macro Archive underwent
the following changes:

 * All archive entries use '#' comment delimiters, rather than 'dnl',
   because we would like those comments to go into the generated
   configure script. It should be simple for everyone to determine
   where the macro came from originally, who wrote it, and where the
   latest version can be retrieved. To achieve this, every macro used
   to start with a distinguished line that shows the URL of its
   respective home page, i.e.:

   | ##### http://autoconf-archive.cryp.to/ax_prog_acme.html

   As it happens, the aclocal utility distributed with Automake
   ignores all comment lines that start with a double hash '##', thus
   those home page URLs will not make it into any automatically
   generated aclocal.m4 file. Duh. To remedy the situation, the
   following markup is now used instead:

   | # =================================================================
   | #        http://autoconf-archive.cryp.to/ax_prog_acme.html
   | # =================================================================

 * The 2.x versions of the GNU GPL and LGPL contain the following
   clause:

   | You should have received a copy of the <GNU LICENSE NAME> along
   | with this program; if not, write to the Free Software Foundation,
   | Inc., 59 Temple Place - Suite 330, Boston, MA 02111-1307, USA.

   Version 3.x, however, smartly refers the reader to the Web:

   | You should have received a copy of the GNU General Public License
   | along with this program. If not, see <http://www.gnu.org/licenses/>.

   This patch changes all GPL2 and LGPL2 macros to do the same, i.e.
   to refer to the GNU web site for the full text of the respective
   license. 

 * Since all m4 files had to be changed in this commit anyway, the
   opportunity was used to increase the auto-fill column for
   documentation from 65 to 75 characters per line. It's a trivial
   change, but it just looks nicer.
