Just some cleanup before I touch this code; switching to typesafe list
macros & putting the data directly inline.

... yes we may need it later, but if and when that happens we can put it
back there. No point carrying around unused things.

1. Packet validation as per RFC 5059 Sec 3.1.3
We won't supporting scope zone BSM as of now, they are dropped now.
Order of the check slightly be changed in code for optimization.
if ((DirectlyConnected(BSM.src_ip_address) == FALSE) OR
(we have no Hello state for BSM.src_ip_address)) {
drop the Bootstrap message silently
}
if (BSM.dst_ip_address == ALL-PIM-ROUTERS) {
if (BSM.no_forward_bit == 0) {
if (BSM.src_ip_address != RPF_neighbor(BSM.BSR_ip_address)) {
drop the Bootstrap message silently
}
} else if ((any previous BSM for this scope has been accepted) OR
(more than BS_Period has elapsed since startup)) {
#only accept no-forward BSM if quick refresh on startup
drop the Bootstrap message silently
}
} else if ((Unicast BSM support enabled) AND
(BSM.dst_ip_address is one of my addresses)) {
if ((any previous BSM for this scope has been accepted) OR
(more than BS_Period has elapsed since startup)) {
#the packet was unicast, but this wasn't
#a quick refresh on startup
drop the Bootstrap message silently
}
} else {
drop the Bootstrap message silently
}
