2915e711f7 Custom number parser to speed up config parsing 
The glibc's generic parser is slow due to its versatility. Specialized
parsers for base-10 and base-16 are much faster and we don't use other
bases.

93af78d2d2 Nest: Do not compare rte.flags during rte_update() 
Route flags are mosty internal state of rtable, they are not significant
to whether a route has changed. With the old code, all routes received as
a part of enhanced route refresh are always re-announced to other peers
due to change in REF_STALE.

4c553c5a5b Filter refactoring: dropped the recursion from the interpreter 
This is a major change of how the filters are interpreted. If everything
works how it should, it should not affect you unless you are hacking the
filters themselves.

Anyway, this change should make a huge improvement in the filter performance
as previous benchmarks showed that our major problem lies in the
recursion itself.

There are also some changes in nest and protocols, related mostly to
spreading const declarations throughout the whole BIRD and also to
refactored dynamic attribute definitions. The need of these came up
during the whole work and it is too difficult to split out these
not-so-related changes.

ca2ee91a80 Filter refactoring: The constant f_val is simply included inside the instruction 
With 32 bits, size of the args is 12 bytes, the f_val is 20 bytes.
With 64 bits, size of the args is 24 bytes, the f_val the same.

This is not so nice on 32 bits, anyway the f_inst itself is
24 vs. 32 bytes and the overall size of filters must be 32k of
instructions to get to one megabyte of RAM eaten by f_inst.

Therefore it seems to be improbable for common user to get into
problems with this change.

a946317fab Filter: Converted static global variables to a filter_state struct. 
The static filter state was messy and blocked the planned parallel
execution of filters. Anyway, this will be also slower as the state
structure must be passed almost everywhere with us.
