From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

This is the client-side extension for status report of git-push.

The "proc-receive" hook may receive a command for a pseudo-reference
with a zero-old as its old-oid, while the result of the hook may point
to an alternate reference and the reference may exist already with a
non-zero old-oid.  Git client may receive a report with extened status
as the following example:

    ok refs/for/master/topic\0ref=refs/pull/123/head old-oid=...

Parse the key-value pairs in the extended status after the null
character of the report, and show the proper reference name, old-oid
and new-oid to the user.

Suggested-by: Junio C Hamano <gitster@pobox.com>
