upload: support --re and --cc options over HTTP

HTTP can't use the older style of passing options as part of
the git receive-pack command line. Use the new style as defined
by https://gerrit-review.googlesource.com/42652 when connecting
over HTTP.

If the Gerrit server is too old to understand the % option
syntax used here one of two outcomes is possible:

- If no topic name was sent the server will fail with an error
  message. This happens because the user tried to do an upload to
  "refs/for/master%r=alice", and the branch does not exist.
  The user can delete the options and retry the upload.

- If a topic was set the options will be read as part of the
  topic string and shown on the change page in the topic field.

Either outcome is slightly better than the current behavior of
just dropping the data on the floor and forgetting whatever the
user tried to supply.
