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.

452e90ba72 Filter: Fix crash with 'where' filters and function calls
The old 'where' code computed size value incorrectly, which leads
to invalid instruction lines and filter errors or crashes.

6479e403ef Filters: If somebody doesn't like _Thread_local, don't fail for now, just be a little slower.
When the parallel execution comes into place, we'll likely enforce this
C11 feature. It's much simpler and also faster than pthread_[sg]etspecific().
