From: Ronnie Sahlberg <sahlberg@xxxxxxxxxx>
Date: Wed, 30 Apr 2014 12:22:42 -0700
Change the ref transaction API so that we pass the reflog message to the
create/delete/update functions instead of to ref_transaction_commit.
This allows different reflog messages for each ref update in a multi-ref
transaction.
