Netlink: Fixed handling of undefined bitfields in filters
...
The default value is obviously false everywhere so we just return zero
if nothing is found, instead of undef.

Kernel: protocol shuts down synchronously
...
Before this commit, on kernel shutdown, the routes were re-exported by
the regular export but treated as withdraw. This was too hairy and
caused unnecessary complexity of the protocol's state machine.
Instead of that, we found out that it makes more sense to just refeed
the routes synchronously and convert to withdraw. This is done by the
direct export access instead of the channel.
It would (maybe) make more sense to run export filters on this in case
the export filter updates the krt_metric attribute, but as this doesn't
work on regular withdraw anyway, it's better for now to just let it be
and maybe somebody in the future fixes this issue.

IO: Ensure that socket rcvbuf is large enough
...
The socket structure has the field rbsize (receive buffer size), which
controls the size of the userspace receive buffer. There is also kernel
receive buffer, which in some cases may be smaller (e.g. on FreeBSD it
is by default ~8k). The patch ensures that the kernel receive buffer is
as large as the userspace receive buffer.

IO: Avoid re-binding accepted sockets to VRF
...
When VRFs are used, BIRD correctly binds listening (and connecting)
sockets to their VRFs but also re-binds accepted sockets to the same VRF.
This is not needed as the interface bind is inherited in this case, and
indeed this redundant bind causes an -EPERM if BIRD is running as
non-root making BIRD close the connection and reject the peer.
Thanks to Christian Svensson for the original patch and Alexander Zubkov
for suggestions.

Additional CLI sockets may now be restricted
...
This allows to have one main socket for the heavy operations
very restricted just for the appropriate users, whereas the
looking glass socket may be more open.
Implemented an idea originally submitted and requested by Akamai.

BFD: Add option to accept zero checksum for IPv6 UDP packets

Some vendors do not fill the checksum for IPv6 UDP packets.
For interoperability with such implementations one can set
