[PATCH 2/6 (v2)] connect.c::read_extra_info(): prepare to receive more than server capabilities

[Junio C Hamano <gitster@pobox.com>]

This still does not actually parse and accept anything more than the list
of server capabilities, but prepares for the uploader that sends more
"extra" information than that.
