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.

261816b0d4 BGP: Cluster list item should be prepended
Commit 3c09af41... changed behavior of int_set_add() from prepend to
append, which makes more sense for community list, but prepend must be
used for cluster list. Add int_set_prepend() and use it in cluster list
handling code.

700bbe60fb The previous fix for spacing was (a) totally out of context, (b) wrong.
Please *read* the code when trying to change it.

Also killed a couple of type clashes.

c0668f3696 Created nest/a-path.c and a-set.c which should contain general operations
on AS paths and community sets.

Moved as_path_prepend() there.

Pavel, please move the other functions as well.
