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.

0d1b3c4c0e Changes print-like filter commands to use a log instead of a stderr.
And extends the log subsystem to better handle 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.

b1a597e0c3 Reimplementation of prefix sets.
Prefix sets were broken beyond any repair and have to be reimplemented.
They are reimplemented using a trie with bitmasks in nodes.
There is also change in the interpretation of minus prefix pattern,
but the old interpretation was already inconsistent with
the documentation and broken.

There is also some bugfixes in filter code related to set variables.
