  pkt-line: allow peeking a packet line without consuming it
  pkt-line: add delim packet support
  upload-pack: convert to a builtin
  upload-pack: factor out processing lines
  transport: use get_refs_via_connect to get refs
  connect: convert get_remote_heads to use struct packet_reader
  connect: discover protocol version outside of get_remote_heads
  transport: store protocol version
  protocol: introduce enum protocol_version value protocol_v2
  test-pkt-line: introduce a packet-line test helper
  serve: introduce git-serve
  ls-refs: introduce ls-refs server command
  connect: request remote refs using v2
  transport: convert get_refs_list to take a list of ref prefixes
  transport: convert transport_get_remote_refs to take a list of ref
    prefixes
  ls-remote: pass ref prefixes when requesting a remote's refs
  fetch: pass ref prefixes when fetching
  push: pass ref prefixes when pushing
  upload-pack: introduce fetch server command
  fetch-pack: perform a fetch using v2
  fetch-pack: support shallow requests
  connect: refactor git_connect to only get the protocol version once
  connect: don't request v2 when pushing
  transport-helper: remove name parameter
  transport-helper: refactor process_connect_service
  transport-helper: introduce stateless-connect
  pkt-line: add packet_buf_write_len function
  remote-curl: create copy of the service name
  remote-curl: store the protocol version the server responded with
  http: allow providing extra headers for http requests
  http: don't always add Git-Protocol header
  http: eliminate "# service" line when using protocol v2
  remote-curl: implement stateless-connect command
  remote-curl: don't request v2 when pushing
