Factor out Unix Pageant's socket creation.

Browse Source 
The code in Pageant that sets up the Unix socket and its containing
directory now lives in a separate file, uxagentsock.c, where it will
also be callable from the upcoming new SSH server when it wants to
create a similar socket for agent forwarding.

While I'm at it, I've also added a feature to create a watchdog
subprocess that will try to clean up the socket and directory once
Pageant itself terminates, in the hope of leaving less cruft lying
around /tmp.
