[PATCH for-4.8] git: Add metadata to the result of `git archive`

[PATCH for-4.8] git: Add metadata to the result of `git archive`

[Andrew Cooper]

When building Xen from a source tarball, commit information is usually lost,
especially if the tarball was generated from a tag.

Have `git archive` automatically fill in metadata at the point of creating the
archive, which is especially useful when using web snapshot links such as:

  http://xenbits.xen.org/gitweb/?p=xen.git;a=snapshot;h=HEAD;sf=tgz

to obtain the tarball.

It would be useful if this could be included in 4.8, and backported to older
releases  (Assuming noone has any objections)

Inclusion in 4.8 - fine by me. I will pick it up at some point.
