draft-ietf-idr-restart. Do not announce actual restart capabilities,
so that this only serves as indicator that we are capable of sending
and receiving the End-of-RIB marker.
leave disabled for now, since the code to actually send the EoR-marker
is currently ifdef'd out (to be fixed soon) and we wanna play safe for
4.0. and juniper doesn't support that capability (which is not a problem
per se) and at the same time has its capability negotiation code completely
fucked up, if a capability is rejected they don't indicate WHICH capability
they reject (which makes that a problem, tho still a small one and we cope).

sessions can be configured to modify the carp demotion counter for a
given interface group (usually, "carp", which has all carp interfaces)
when the session is not established. once the session is established for
60 seconds, the demotion is cleared.
this, used correctly, can prevent a bgpd-box which lost all sessions (and
thus has no routes) to be carp master, while the backup has sessions.

as soon as F_ORIGINAL come the counters would no longer be correct and in the
end max-prefix would no longer work. Add additinal counters for F_ORIGINAL
prefixes and bump the correct conter depending on the prefix flags.

The default filter_sets are converted into match filter rules that get
evaluated first. Simplifies code massively -- mainly the config reload
part -- and makes softreconfig out a piece of cake. "get it in" henning@

a status code to indicate wether the request was processed successfully
or wether an error occured and if so what kind of error.
no more "IMSG_CTL_NEIGHBOR_ with unknown neighbor foobaz" in the log

equality. This function is a bit more complicated than a memcmp() because there
are types that need to be considered equal e.g. ACTION_SET_MED and
ACTION_SET_RELATIVE_MED. Also ACTION_SET_COMMUNITY and ACTION_SET_NEXTHOP

network and neighbor statements and the routes are labeled accordingly.
While doing that fix some mem-leaks by introducing filterset_free() and
remove the free on send option of send_filterset().
This took a bit longer because we need to carefully track the rtlabel id
refcnts or bad things may happen on reloads.
henning@ looks fine

long AS pathes in one or the other direction. It weights a prefix at a very
late stage in the decision process. This is a nice bgpd feature to traffic
engineer networks where most AS pathes are equally long.
