Subject: [PATCH v4 19/35] push: pass ref patterns when pushing

From: Brandon Williams <[email-masked]>
Date: Wed, 28 Feb 2018 15:22:36 -0800

Construct a list of ref patterns to be passed to 'get_refs_list()' from
the refspec to be used during the push.  This list of ref patterns will
be used to allow the server to filter the ref advertisement when
communicating using protocol v2.
