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.

dfb3eb7716 Filter: Fix function comparison
Check the SYM_FLAG_SAME in new symbols. The old code checked that
in old symbols (f2).

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.

0edf0c8cd9 Support for address family constants

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.

The old 'where' code computed size value incorrectly, which leads
to invalid instruction lines and filter errors or crashes.
