Multicast replication

[Howard Chu <hyc@symas.com>]

Was thinking it would be great to use a multicast reliable datagram protocol 
for replication; that would allow keeping multiple consumers up to date 
without consuming multiples of the provider's network bandwidth. A decent MRDP 
would also make for more efficient MMR at the same time. In syncrepl the 
refresh phase would still occur over a regular TCP session, but the transition 
to persist phase could include a multicast group membership. This may be 
better suited to the ldapext mailing list, but thought I'd get some early 
feedback here first.
