[PATCH] Show more details of packfile with verify-pack -v.

Browse Source 
This implements show_pack_info() function used in verify-pack
command when -v flag is used to obtain something like
unpack-objects used to give when it was first written.

It shows the following for each non-deltified object found in
the pack:

    SHA1 type size offset

For deltified objects, it shows this instead:

    SHA1 type size offset depth base_sha1

In order to get the output in the order that appear in the pack
file for debugging purposes, you can do this:

 $ git-verify-pack -v packfile | sort -n -k 4,4
