Housekeeping: implement a tool for producing intermediate alpha tarballs.

Intermediate tarballs have the same version number as initial alpha
version, to which is appended a suffix "-N", where N is the number of
commits between the current git HEAD and the original alpha release.

Additionally, the --version (or -version, for MH) output has been changed
to include the N and the git description (for all releases, but stable).

* .gitignore: Update.
* Makefile.am: Remove git-describe and git-describe.h goals.
(alpha, alphacheck): Rewrite.
* configure.ac (GITINFO): New subst variable.
* include/mailutils/Makefile.am (gitinfo.h): New built source.
* libmailutils/cli/cli.c: Include gitinfo.h
(mu_version_hook): Rewrite.
* mh/mh_getopt.c: Include gitinfo.h
(mh_version_hook): Rewrite.
* mu-aux/gitinfo.pl: New file.
* mu-aux/Makefile.am (EXTRA_DIST): Add gitinfo.pl
* mu/Makefile.am (mu-setup.c): Add dependency
* testsuite/testsuite.inc (MUT_VERSION): Account for changes in
version output.
