[PATCH 2/8] revision: factor out add_pending_sha1

["René Scharfe" <rene.scharfe@lsrfire.ath.cx>]

This function is a combination of the static get_reference and
add_pending_object.  It can be used to easily queue objects by hash.

Signed-off-by: Rene Scharfe <rene.scharfe@lsrfire.ath.cx>

The next patch is going to use it in checkout.
