Better handling of too long attributes
...
This patch extends the length for attributes from 1024 to 2048
(because both AS_PATH and AS4_PATH attributes take 2+4 B per AS).
If there is not enough space for attributes, Bird skips that
route group. Old behavior (skipping remaining attributes)
leads to skipping required attributes and session drop.

Fix race condition that breaks BGP connections after reconfigure.
...
RFC says that only connections in OpenConfirm and Established state
should participate in connection collision detection.
The current implementation leads to race condition when both sides
are trying to connect at the almost same time, then both sides
receive OPEN message by different connections at the almost same
time and close the other connection. Both connections are
closed and the both sides end in start/idle or start/active
state.
