[PATCH] Update of my February patches to CVS automake

[Bonzini]

This patch does these things:
* add PDF support via texi2dvi's --pdf option.  Triggered by `make pdf'

* test for --help and --version in gnits mode

* better checks for distribution of license files
** prefer COPYING.LESSER to COPYING.LIB (error in gnits mode, warning in
   gnu mode), distribute COPYING.LESSER automatically
** in gnu or gnits modes, don't require COPYING if COPYING.LESSER is there

* support for shtool

I can sign a copyright assignment if it's accepted.  The code was
already more or less revised when I submitted patches relative to
Automake 1.5 back in February; this is against CVS automake, checked
out about two hours ago (2PM in Europe).

Here is the ChangeLog entry.
