Merge branch 'jt/fetch-v2-sideband'
"git fetch" and "git upload-pack" learned to send all exchange over the sideband channel while talking the v2 protocol. * jt/fetch-v2-sideband: tests: define GIT_TEST_SIDEBAND_ALL {fetch,upload}-pack: sideband v2 fetch response sideband: reverse its dependency on pkt-line pkt-line: introduce struct packet_writer pack-protocol.txt: accept error packets in any context Use packet_reader instead of packet_read_line
