usr.sbin/bgpd : bgpd.h rde.c rde.h rde_peer.c session.c
Log message:
Handle IMSG_SESSION_* messages immediatly when received and do not put
them on the per peer imsg queue. This is mainly for IMSG_SESSION_DOWN.
Delaying the session down can race against IMSG_SESSION_ADD which is
handled immediatly and as a result an establised connection may be
removed in the RDE because of it.
The various graceful restart imsgs need similar treatment for similar
reasons. In the end when a session is reset/closed the RDE needs to
stop all work and flush the per peer imsg queue.
With this only update and route refresh messages are handled via the
imsg queue.
