5a14df3950 Filter: Instruction codes named as enum 
The two-letter instructions were quite messy but they could be easily
read from memory dumps. Now GDB (since 2012) supports pretty printing
enum values and GCC checks the switch construction for missing enum
values so we are converting the nice two-byte values to enums.

Anyway, the enum still keeps the old two-byte values to be able to read
the instruction codes even without GDB from plain memory dump.

69a8259c5e Allows sticky link-local neighbors. 
Allows using NEF_STICKY neighbors with link-local addresses. This is
used for static route nexthops, they can be specified like fe80::1%eth0
.

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.

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.

cc590a11a7 Changed syntax of expressions. Each `expr' can be now either a numeric literal 
or a symbol or parenthesised filter expression.

e3f2d5fce3 Cleanup of configuration. 
o  Use `expr' instead of `NUM' and `ipa' instead of `IPA',
   so that defined symbols work everywhere.
o  `define' now accepts both numbers and IP addresses.
o  Renamed `ipa' in filters to `fipa'.

Pavel, please update filters to accept define'd symbols as well.
