As much as it hurts me to do this, define MAX_PEER_BUCKETS to 1 for Asterisk 1.4
to maintain the behavior that the order entires are specified in the config can
determine matching order against them.  This is going to change in trunk, so has
been marked as deprecated behavior in UPGRADE.txt.

You can change the define for the number of buckets to get the increased performance
from the hash table.

 * The "mailboxdetail" option has been deprecated.  Previously, if this option
   was not enabled, the 2 byte MSGCOUNT information element would be set to all
