Of course, chucking this out:
	fatal: ConnectionsPerPeriod has been deprecated

and then aborting violates POLA.  If it's been deprecated, just ignore
it for a while, but don't stop functioning because of a "dead" directive.
Got bit this morning by that (our ssh/sshd config's are somewhat different
from 'normal', and a later experiment with merge didn't remove the
offending line, either.  Thank heavens for serial consoles.

The approach here was not thought through at all, especially with:

  uxb 22# grep -i connectionsperperiod /usr/src/UPDATING
  uxb 23#

on a fully up-to-date RELENG_4 src/ tree.

I would ask, that in -STABLE at least, the fatal error be backed
out to a warning, at least for a few months (with sshd ignoring the
directive, and continuing to run), and then only move to a fatal
error + die.
