fdd -- file-descriptor daemon

Fdd allows to share socketpair over a unix domain socket. The typical flow is as follows:

1. Start the fdd daemon:

   Copy

   $ fdd init
   

2. Create a bunch of socketpair shares:

   Copy

   $ fdd share /tmp/foo
   $ fdd share /tmp/bar
   

This will create /tmp/foo and /tmp/bar that process clients can connect too. Once connected, they can use recvmsg1 to receive each side of the socketpair. If two different process do this, they then have a channel to talk to each other.
