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
both expressions.

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

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)).

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

Also another minor bugfix.

6781e5213b FIXME's cleaned up: I have actually fixed things without killing
comments.

There are no urgent FIXME's in filters. Perhaps we should start with
documentation?

455ca441d9 Check that prefixes are really prefixes + fix config file to
comply. (:-( 1.2.3.4/8 looks nicer than 1.0.0.0/8).

48f9e01954 Filters: write access to dynamic attributes should actually work. It
would be nice to find method of testing such beasts.

f31156ca21 Filters: first parts of extended attributes being read-write. It can
not actually work since I do not do rta/rte cow, yet.

c7b43f33ae Split inst->code into inst->code and inst->aux. Both are only 16 bit,
so aux is suitable for storing type but not much more.

4515bdba4f Fixed order of arguments for function call.
Enumeration types should work once CF_ENUM() is ready.

Created test.conf for testing of filters. (I'm currently thinking
about ./tests in root directory which will just fire all available
tests...)

cb8034f42c First try on enumerational types.
Mj's noassoc removed: this brings back shift/reduce conflict but
it makes parser actually work. Mj please check it. IF/THEN/ELSE still
will not work.

6542ece91a Function calling in filters works - somehow. Calling syntax is
currently very ugly, beware. Variables are not really local - that
needs to be fixed.

4107df1d1b Implemented two new symbol handling functions:
o  cf_define_symbol() -- it assigns a meaning to a symbol, bailing
     out if it already has one.
  o  cf_find_symbol() -- finds symbol by name and creates it if not found.

Also modified filter/config.Y to make use of the first function.

36bbfc704c Updated filters: they now actually see IP/pxlen of net being filtered,
gateway, and who told us, so they can do usefull jobs from now on.

it belongs. (f-util.c stays there for auxiliary and non-important things.)

e0f2e42f4f A couple of filter tweaks:
o  Introduced struct filter which serves as an external reference
      to filter. Using struct symbol for this is unwise since it doesn't
      allow extra information attached to the filter and it also forces
      all filters to be named.
   o  Implemented config rule 'filter' which matches either named filter
      or an embedded unnamed filter (`{ <filter> }').
   o  Fixed totally bogus comment at the top of filter.h.
   o  Added a missing prototype for f_run() to filter.h.
