[REROLL PATCH v2 0/8] Remote helpers smart transport extensions

Changes from reroll v1:

- Wording fix in pass unknown protocols patch commit message
- Fix NO_CURL and hopefully make remote-http building bit clearer
- Remove extraneous fflush(stderr)
- Simplify remove_ext_force().
- Use strchr() instead of strchrc(). strchr() not const-correct, but...
- Simplify URL checking in is_url()
- Expand stdin and stdout in remote helper documentation
- _recvline -> recvline_fh
- _process_connect -> process_connect_service
- Reworded remote archive patch message
- gitoptions -> transport_options.
