Differentiate between error delay and connect/reconnect delay.
...
The difference is here to reject incoming connections in the
first case.

Fixes BGP IPv6 link local next hop handling.

When sending 'third party' BGP update, Bird used bogus link local
addresses instead of addresses it received before.

Better handling of AS4 optional attribute errors
...
AS4 optional attribute errors were handled by session
drop (according to BGP RFC). This patch implements
error handling according to new BGP AS4 draft (*)
- ignoring invalid AS4 optional attributes.

add some checks and ignore incoming capabilities when capabilities
are disabled.

...
When capability related error is received, next connect will be
without capabilities. Also cease error subcodes descriptions
(according to [RFC4486]) are added.

Fixes bug related to reconfiguration of BGP.
...
BGP keeps its copy of configuration ptr and didn't update it during
reconfiguration. But old configuration is freed during reconfiguration.
That leads to unnecessary reset of BGP connection during reconfiguration
(old conf is corrupted and therefore different) and possibly other strange
behavior.

Major changes to BGP
...
Fixes two race conditions causing crash of Bird, several unhandled
cases during BGP initialization, and some other bugs. Also changes
handling of startup delay to be more useful and implement
reporting of last error in 'show protocols' command.

Rewritten the I/O loop. All socket operations are now safe, meaning that
...
you can delete the socket from anywhere in the hooks and nothing should break.
Also, the receive/transmit buffers are now regular xmalloc()'ed buffers,
not separate resources which would need shuffling around between pools.
sk_close() is gone, use rfree() instead.

Better selection of link-local NLRI addresses, at least for our own

address. Need to do it better for the other neighbors -- the current
solution works only if they use the standard 64+64 global addresses
and the interface identifier in lower 64 bits is the same as for the
link-scope addresses.
