transport: add git-send-pack support to local/ssh. (#163)

* protocol/packp: add Packfile field to ReferenceUpdateRequest.
* protocol/packp: add NewReferenceUpdateRequestFromCapabilities.
* NewReferenceUpdateRequestFromCapabilities can be used to create
  a ReferenceUpdateRequest with initial capabilities compatible with
  the server.
* protocol/packp: fix new line handling on report status.
* transport/file: test error on unexisting command.
