Summary:
This adds a new class which listens on a Unix domain socket for clients that
wish to gracefully take over Eden's FUSE mount points. The goal is to
eventually enable graceful restart functionality for eden.
It would be nice if we could use the existing thrift server socket for this,
but thrift doesn't provide low-enough level APIs so that we can send
credentials and file descriptors over the socket using SCM_CREDENTIALS and
SCM_RIGHTS. Using our own separate socket is the easiest way to accomplish
this instead.
For now eden just listens on this socket and logs a message when a client
connects; this diff does not yet contain logic for performing mount point
takeover.
