Merge branch 'jn/promote-proto2-to-default'

Browse source 
The transport protocol version 2 becomes the default one.

* jn/promote-proto2-to-default:
  fetch: default to protocol version 2
  protocol test: let protocol.version override GIT_TEST_PROTOCOL_VERSION
  test: request GIT_TEST_PROTOCOL_VERSION=0 when appropriate
  config doc: protocol.version is not experimental
  fetch test: use more robust test for filtered objects

Experimental. If set, clients will attempt to communicate with a
server using the specified protocol version. If unset, no
attempt will be made by the client to communicate using a
particular protocol version, this results in protocol version 0
being used.
If set, clients will attempt to communicate with a server
using the specified protocol version. If the server does
not support it, communication falls back to version 0.
