CARP - patch for preempt + mastership bug from openbsd38 implementation

[Damien Fleuriot]

Hello list,



I've submitted a PR + patch regarding a bug in carp's implementation
from openbsd38 and lower.

When preemption is enabled, a carp interface automatically assumes
INIT->MASTER role without even checking if there is a faster master around.

This breaks existing connections for people that don't use pfsync (or
for connections which weren't synched yet) and confuses switches and
clients alike.

I'd like to make sure this gets looked at, so it makes 9.0's release if
the carp implementation for 9.0 is still based on openbsd38 or lower.
