Make inter-release --version output more useful.

Now, each unofficial build has a version "number" like 1.8.8.1.19-58dd,
which indicates that it is built using the 19th change set
(in _some_ repository) following the "v1.8.8.1" tag, and that 58dd
is a prefix of the commit SHA1.
* configure.ac: Run it to set the version.
(PED_MAJOR_VERSION): Derive from $PACKAGE_VERSION.
(PED_MINOR_VERSION): Likewise.
(PED_MICRO_VERSION): Likewise.
Remove the test that would ensure $PACKAGE_VERSION != $PED_VERSION,
now that the latter is derived from the former.
* Makefile.am (dist-hook): Arrange so that .version appears only
in distribution tarballs, never in a checked-out repository.
* .gitignore: Add .version here, too.  Just in case.
* lib/.gitignore: Remove now-generated (by bootstrap) file.
* build-aux/.gitignore: Likewise.

Ensure that $(VERSION) is up to date for dist-related targets.
* GNUmakefile: Arrange to rerun autoconf, if the version reported by
git-version-gen doesn't match $(VERSION), but only for dist targets.
