1967fe4fa6 Route: moved rte_src pointer from rta to rte
It is an auxiliary key in the routing table, not a route attribute.

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.

93c5a314da Dropping the RTS_DUMMY temporary route storage.
Kernel route sync is done by other ways now and this code is not used
currently.

fd9f0c0640 Configuration strings are constant.
This is merely a const propagation. There was no problem in there.

2755002890 Filter: Optimize IPv4 prefix sets
Use separate IPv4 and IPv6 implementation of prefix sets. Just this
change makes IPv4 prefix sets 60% smaller and 50% faster.

ef8c45749c Filter: Fix typecheck for AND/OR.
Do not apply dynamic type check for second argument of AND/OR, as it is
not evaluated immediately like regular argument would be.

Thanks to Mikael for the bugreport.

3dabf7b8d0 Test: Improve filter_test
Initial parsing of test.conf must be done directly in filter_test main,
while reconfiguration is handled as a regular test. Also fix several
minor issues in test code.

c00c20a799 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.

6fbcd8914a Filter: Parse-time typechecks
Most expressions can be type-validated in parse time. It is not
strong enough to eliminate runtime checks, but at least one gets
errors immediately during reconfigure.

3f477ccb03 Filters: Function body comparison result now used.
Function bodies were compared in post-parse time, yet the result was not
used and the functions were incorrectly considered the same as before.

Now the result is used to reload affected protocols.
