When someone is building Coccinelle from source on a git tree
with some modifications we currently cannot tell what type of
modifications, if any, were done. Add a localversion info
postix which will be pegged onto the version string *iff* the
git tree used has either a change non-commited  yet or if the
git tree has some commits beyond what was officially released
and tagged. This also lets release managers skip the local
version postfix tag when preparing an official coccinelle
release, by using:

./autogen --ignore_localversion

This can be used by release managers when preparing a release
prior to pegging a release with a tag, so that the released
default configure scripts can be commited prior to marking
the git tree with a release tag. This is disabled by default,
so that the only way that you won't get a postfix is if you
used a blessed official release.

If you have a dirty tree with some uncommited changes the
version will be postfixed with -dirty. For exam...
