Currently there is no way to remotely create a symref.

It should be easy to make DAV based http push create a symref
file.

The native "send-pack" protocol does not support such feature,
so this needs a protocol extension, which hopefully would be
not too involved.

Also, to be symmetric, we would need a protocol extension on the
"fetch-pack" protocol side to allow fetchers to find out which
one is a symref pointing out what other ref.  The lack of the
information is why git-clone has to guess.
