git-pack-objects: write the pack files with a SHA1 csum

We want to be able to check their integrity later, and putting the
sha1-sum of the contents at the end is a good thing.  The writing
routines are generic, so we could try to re-use them for the index file,
instead of having the same logic duplicated.

Update unpack-objects to know about the extra 20 bytes at the end
of the index.

Add "--pretty=full" format that also shows committer.

Also move the common implementation of parsing the --pretty argument
format into commit.c rather than having duplicates in diff-tree.c and
rev-list.c.

Add git-verify-tag script

Here is a script to simplify validating the gpg signature created by
git-tag-script. Might be useful to add to the git tree so that people
don't have to search for the right post in the git mailinglist archives
