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.

112d71a73f Fixes syntactic priority of '.' .

priority.

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.

221135d6bf Include "lib/string.h" instead of <string.h>. It should give us bzero()

f2c6c80a24 I tried to turn on the YYERROR_VERBOSE switch, but bison is buggy as hell,

bc2fb68098 Parse CLI commands. We use the same parser as for configuration files (because
we want to allow filter and similar complex constructs to be used in commands
and we should avoid code duplication), only with CLI_MARKER token prepended
before the whole input.

Defined macro CF_CLI(cmd, args, help) for defining CLI commands in .Y files.
The first argument specifies the command itself, the remaining two arguments
are copied to the help file (er, will be copied after the help file starts
to exist). This macro automatically creates a skeleton rule for the command,
you only need to append arguments as in:

	CF_CLI(STEAL MONEY, <$>, [[Steal <$> US dollars or equivalent in any other currency]]): NUM {
		cli_msg(0, "%d$ stolen", $3);
	} ;

Also don't forget to reset lexer state between inputs.

dce267832a Basic support for IPv6. The system-dependent part doesn't work yet,
but the core routines are there and seem to be working.

   o  lib/ipv6.[ch] written
   o  Lexical analyser recognizes IPv6 addresses and when in IPv6
      mode, treats pure IPv4 addresses as router IDs.
   o  Router ID must be configured manually on IPv6 systems.
   o  Added SCOPE_ORGANIZATION for org-scoped IPv6 multicasts.
   o  Fixed few places where ipa_(hton|ntoh) was called as a function
      returning converted address.

0e02abfd57 From now we support multiple tables. The master_table variable is
definitely gone. Both rte_update() and rte_discard() have an additional
argument telling which table should they modify.

Also, rte_update() no longer walks the whole protocol list -- each table
has a list of all protocols connected to this table and having the
rt_notify hook set. Each protocol can also freely decide (by calling
proto_add_announce_hook) to connect to any other table, but it will
be probably used only by the table-to-table protocol.

The default debugging dumps now include all routing tables and also
all their connections.

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.

23b1539bf9 Filters upgraded - a bit. Moved code to filter.c because it is where
it belongs. (f-util.c stays there for auxiliary and non-important things.)

7f400d1c62 After today's lengthy discussions about filter syntax, let's clean up
whitespace/semicolon rules for whole config file:

   o  All non-zero amounts of whitespace are equivalent to single space
      (aka `all the whitespace has been born equal' ;-)).
   o  Comments count as whitespace.
   o  Whitespace has no syntactic signifance (it can only separate lexical
      elements).
   o  Consequence: line ends are no longer treated as `;'s.
   o  Every declaration must be terminated by an explicit `;' unless
      or by a group enclosed in `{' and `}'.

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.

c9b6670608 Original expr' is back, filter expressions renamed to term'.
In the future, we'll allow any filter term in place of `expr' and we'll
just evaluate it immediately, but not now as we have no evaluation
routines.
