fe9f1a6ded Initial commit on integrated BIRD 
New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible.

The commit is WiP, some protocols are not yet updated (BGP, Kernel),
and the code contains some temporary scaffolding.

Comments are welcome.

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

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

c8a6b9a3d1 Rewrite of buggy AS path matching. 
Old AS path maching supposes thath AS number appears
only once in AS path, but that is not true. It also
contains some bugs related to AS path sets.

New code does not use any assumptions about semantic
structure of AS path. It is asymptotically slower than
the old code, but on real paths it is not significant.

It also allows '?' for matching one arbitrary AS number.

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.

083c43e22e fixes some 64-bit related bugs. 
Filter code used 'aux' integer field of 'symbol' struct to store ptr
to next symbol and both 'aux2' and 'def' fields for value.
Changed to just 'def' for value and 'aux2' for ptr to next symbol.
Also another minor bugfix.

e29fa06ece New read-only route attribute 'proto' added. It returns a string 
representing a name of the protocol that originated the route.
Strings can be compared using = or matched using ~. Routes can
be filtered, for example:

show route where proto ~ "bgp1*"
