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.

Route: moved rte_src pointer from rta to rte

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.

Filter: Better constant promotion
...
We use constant promotion from IPv4 to Router-ID values, as they have
same literals. Instead of ad-hoc code in filter instructions, add
constant promotion code to parse-time typecheck code.

Most expressions can be type-validated in parse time. It is not
strong enough to eliminate runtime checks, but at least one gets
