Mark Johnston bfd03046d1 unix: Add support for atomically setting the socket mode 
With this patch, it is possible to call fchmod() on a unix socket prior
to binding it to the filesystem namespace, so that the mode is set
atomically.  Without this, one has to call chmod() after bind(), leaving
a window where threads can connect to the socket with the default mode.
After bind(), fchmod() reverts to failing with EINVAL.

This interface is copied from Linux.

The behaviour of fstat() is unmodified, i.e., it continues to return the
mode as set by soo_stat().
