can be used instead of doing direct fiddling around with struct in_addr.
Use it in a few cases where it makes the code more similar between INET
and INET6 case.
OK denis@

there is still a little difference regarding handling of the verbosity
value that will be handled later.

that it is possible to use OpenBGPD as a route-reflector for VPNv4.
Some clean up of the BGP MP code so that multiple protocols are easier
supported. kroute/kernel support not yet done but comming.
OK henning@, reyk@

else. Adds conversion functions to map AFI/SAFI and the Unix AF_ values
from and into AID used in bgpd. This is needed to support things like MPLS
VPN and other upcomming changes that need to play a lot with AFI/SAFI pairs.
Mostly mechanical change, henning@ has no particular issues with this.
Must go in so that I can continue working.

trees and the rib trees are also not split.
Looks good henning@

work by changing the way the RDE DB is built. struct prefix and struct
pt_entry are simplified and extended with a rib_entry where the decision
tree is run on. From now on a prefix can only reside on one particular RIB
which simplifies the code a bit. Currently there are two fixed ribs
(adj-rib-in and the local-rib) which needs to be made more dynamic in
upcomming commits.
This is work in progress, the RDE seems to work for me and sthen@ (no flames
comming out of our testrouters but there is still a lot missing)
Move into the tree to simplify developement -- henning@

- dedicated pipe between the SE and the RDE for control messages
- restartable RB tree dumps in the RDE
- queuing limits both in the SE and RDE
The result is a dramatic decrease of memory consumption on operations like
bgpctl show rib. Previously all messages where first stored in the RDE
then passed to the SE where they got queued in case bgpctl was not fast enough.
Now only a small number of messages is generated and passed to the SE and
the SE has an additional limit instead of acting like an infinite buffer.
Without this the bgpd on bgpd.networx.ch would not survive a single minute.
looks good henning@

prefix tree changed form a hash table to a per AF RB tree.
OK henning@ some ideas are from Brent Graveland.

is more appropriate. The rde uses now in most cases struct bgpd_addr.

the error number as parameter instead of accessing errno, because in one
place the error number was not in errno but fetched from a socket.
now, of course it makes much more sense to just set errno to the error number
just fecthed in this one place instead of having hundreds of fatal() calls
all transfer the errno round and round and round...
fix this, and also provide a fatalx, which does not care for errno and doesn't
invoke strerror.
oh, btw, in the place where we fetch the err # from the socket, we don't
call fatal anymore anyway...

introduce msgbuf API and bundle all info needed for the write buffers in a
struct msgbuf.
also switch to a write queue per handled connection (each bgp session, each
pipe) instead of one big one.
fixes some subtle problems and is overall nicer.

started by me some time ago with moral support from theo, the proceeded up to
the point where the session engine worked correctly. claudio jeker joined
then and did a lot of work in the RDE.
it is not particulary usefull as application right now as parts are still
missing but is imported to enable more people to work on it.
status:
BGP sessions get established fine, OPEN messages and then KEEPALIVEs
exchanged etc. session FSM works fine; NOTIFICATIONs are handled fine, and
all connection drops etc I provoked get handled fine.
Incoming UPDATE messgages are parsed well and the data entered to the RIB,
the decision process is not yet there, neither is outgoing UPDATEs or sync
to the kernel routing table.
not connected to the builds yet.
