a861727d98 Split route data structure to storage (ro) / manipulation (rw) structures. 
This should help a lot with keeping the route machinery and allocations
clean. This commit also changes behaviour of rte_update() with cached
rta. Newly, calling rte_update() keeps the number of rta references.

1967fe4fa6 Route: moved rte_src pointer from rta to rte

e64fd37675 Route export: rejected by filter bitmap 
If a route has been rejected by filter, store that information
to avoid repeated export filter runs on rejected routes.

a267d569ee KRT: Using obligatory export table when non-trivial filters are applied. 
When the kernel filter is anything more sophisticated than FILTER_ACCEPT
or FILTER_REJECT, we should ensure that the old route being sent to the
kernel protocol is really what was sent there before. This fixes the old
misbehavior when an unfiltered old route was used.

b5899ad768 Unix socket: Path length check directly before copying the path. 
This is not needed as the string is always short enough, anyway
it may be needed in future and one strlen during BIRD start is
cheap enough.
