BOOTP: Disentangle BSDP naming from PacketCable. 

BSDP (Boot Server Discovery Protocol, layered upon BOOTP) is entirely Apple's
creation, and has nothing to do with PacketCable as far as I can tell, so let's
not label it as PacketCable.

BSDPD is one possible name for a daemon that speaks the BSDP protocol, and it
seems more reasonable to use the name of the protocol here, so let's replace
"BSDPD" references with "BSDP", and use CLIENT and SERVER to better identify
the Vendor Class ID prefixes.
