a03ede6493 Fixes a tricky bug in route filtering.
Route attributes was used after rta was freed during copy-on-write in
filter code. This causes some random crashes, esp. with multipath
routes.

26d92bb892 A hack to distinguish if..else from else: in case.
The old BIRD grammar needs two lookaheads to distinguish if..else from
else: in case, which caused the parser to fail on some combinations of
both expressions.

This patch replaces two tokens 'else' ':' by one token 'else:' to fix
that.

ba5c0057ed Extends pair set syntax, matching and deleting against clist.
Expressions like (123,*) can be used in pair set literals, clists can be
matched against pair sets (community ~ pairset) and pair sets can be
used to specify items to delete from clists (community.delete(pairset)).

dfd48621d1 Replaces the algorithm for building balanced trees.
Changes the time complexity of the algorithm from O(n^2) to O(n*log(n)).
This speeds up loading of huge DEC-IX config from 128 s to 15 s. It also
makes the code significantly simpler.
