Path to allow abstract socket addresses.

Using sockets with a real pathname is problematic (see bug #1329). It
works much better if we can use 'abstract' sockets. They don't pollute
the file system, and thus they disappear as soon as the listening
program exits.

This patch makes OpenSSH interpret a leading '@' in the ControlPath to
mean that an abstract socket should be used -- it'll replace the @ with
a zero byte. Now I don't need the (original) patch in bug #1329 and
everything works without leaving stale sockets behind.
