Make sasyncd fail back correctly with carp preemption enabled.

Hold the carp demotion when booting, to prevent carp from preempting until
we've sync'd with our peers.  This adds a new CTL_ENDSNAP message to the
exchange between the sasync daemons to indicate when the complete snapshot
has been sent. Undemote after 60 seconds, or when recieve a CTL_ENDSNAP from
all our peers.

Syntax is slightly changed, removing the 'carp' keyword (so do
"interface carp0" rather than "carp interface carp0". Adds 'group <ifgroup>',
defaults to the 'carp' group.
