For those tests using exabgp convert them all to use `neighbor X timers
connect 1`. I have noticed that occassionally when looking at the
support files for tests run that peers are in a wait period for
reconnecting which is longer than the test is waiting to converge.

When bgp is started up and reads the config in *before* it has
received interface addresses from zebra, shared_network can
be set to false in this case. Later on once bgp attempts to
reconnect it will refigure out the shared_network again( because
it has received the data from zebra now ). In this case
tell bfd about it.

At startup, there is no peer up message for loc-rib instance peer.
Instead, a global peer up message with address 0.0.0.0 is sent.
Such message is wrong, violates the RFC and should be dropped by
a strict collector. Actually, the peer type message sent is wrong,
and should be set to LOC-RIB peer type.
Fix this by changing the peer type of peer up message to either
loc-rib or global instance peer type.

Currently the zapi reconnection is once every 10 seconds
for the first 3 times and then once every 60 seconds from then
on out. We are seeing interesting behavior under loaded systems
where zebra is just slow to come up and daemons are spending a long
time waiting to connect. Let's just make things a bit more aggressive.
Change the code to attempt to reconnect once every second for 30 seconds
and then change to once every 5 seconds from then on out.
This should help with non-integrated configuration on system startup.

If the socket associated with the auto-rp fails to initialize then
the memory for the auto-rp is just dropped on the floor. Additionally
any type of attempt at using the feature will just cause pimd to crash,
when the pointer is derefed. Since it is derefed all over the place
without checking.
Clearly if you cannot bind/use the socket let's allow continuation.

This would give more details why at some point we return deny, no match, etc.
Before this we have sometimes (I don't know why), e.g.:
```
Route-map: null, prefix: 192.168.2.0/24, result: deny

Introduced the idea of setting the socket buffer
send/receive sizes. BSD's in general have the fun
issue of not allowing nearly as large as a size as
linux. Since the above commit was developed on linux
and not run on bsd it was never tested. Modify the
codebase to use the backoff setsockopt that we have
in the code base and use the returned values to allow
us to notice what was set and respond appropriately.

Currently if you have this sequence of events:
a) BGP starts
b) BGP reads cli that has bfd configuration
c) BGP attempts to install bfd configuration but fails because
zebra is not connected to yet
d) BGP connects to zebra
e) BGP receives resend bfd code from bfdd
f) BGP was not sending down the unsent data to bfd, never causing
the bfd session to be established.
So effectively bfd was attempting to install but failed
and then when it was asked to replay everything it decided
that the bfd information for a particular peer was actually
installed and does not need to be resent. Modify the code
such that the bfd code now tracks failed installation and
allows the resend of data to bfdd.

an early phase that opens the socket, and a later phase that

Multiple BMP tests can run in parallel but, when one instance ends,
it kills the BMP server process of all BMP tests.
Save the PID of a BMP server and only kill it at the end.
