Exclusive exec() path, format after partition.

Sadly setexeccon() is process global, so we need to carefully ensure
that all exec() are mutually exclusive to avoid transitioning into
unwanted domains.  Also, because we have several threads floating
around, we need to guard all our FDs with O_CLOEXEC.

Format all newly created volumes immediately after partitioning,
but silence all events emitted from those volumes to prevent the
framework from getting all excited.  Unify all notify events under a
single codepath to make them easy to silence.

Sent SIGINT before escalating to SIGTERM when unmounting.
