transport: convert get_refs_list to take a list of ref prefixes
Convert the 'struct transport' virtual function 'get_refs_list()' to optionally take an argv_array of ref prefixes. When communicating with a server using protocol v2 these ref prefixes can be sent when requesting a listing of their refs allowing the server to filter the refs it sends based on the sent prefixes. This list will be ignored when not using protocol v2. Signed-off-by: Brandon Williams <bmwill@google.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
