[PATCH v3 0/3] git-remote-fd & git-remote-ext

This adds two new remote helpers.

* git-remote-fd, which connects to git service on given file descriptor(s),
useful for graphical user interfaces that want to use internal ssh client.

* git-remote-ext, which connect to git service using external program. Useful
for connecting using odd one-off ssh options, to services in abstract
namespace, using unix domain sockets, using TLS, etc...

Changes from last time:
* Actually include all needed files (oops)
* Lots of documentation wording changes and some minor code changes.
