Allow EA type to be set to 'undefined' which overrides all further definitons
of that EA in the same list and causes ea_find() to fail unless you add
EA_ALLOW_UNDEF to the second argument.
ea_sort (resp. ea_do_prune()) removes all undef'd attributes from the list.

Added some temporary examples of how to define CLI commands (search for CF_CLI).
To define a new command, just add a new rule to the gramar:
CF_CLI(COMMAND NAME, arguments, help-args, help-text) {
what-should-the-command-do
} ;
where <arguments> are appended to the RHS of the rule, <help-args> is the
argument list as shown in the help and <help-text> is description of the
command for the help.
<what-should-the-command-do> is a C code snippet to be executed. It should
not take too much time to execute. If you want to print out a lot of
information, you can schedule a routine to be called after the current
buffer is flushed by making cli->cont point to the routine (see the
TEST LONG command definition for an example); if the connection is closed
in the meantime, cli->cleanup gets called.
You can access `struct cli' belonging to the connection you're currently
servicing as this_cli, but only during parse time, not from routines scheduled
for deferred execution.
Functions to call inside command handlers:
cli_printf(cli, code, printf-args) -- print text to CLI connection,
<code> is message code as assigned in doc/reply_codes or a negative
one if it's a continuation line.
cli_msg(code, printf-args) -- the same for this_cli.
Use 'sock -x bird.ctl' for connecting to the CLI until a client is written.

If the main event queue is not empty, call select() with zero timeout, so
that the events are ran again after the FD's are checked. This allows us
to schedule I/O checks between processing of user commands.

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.

Events now return a value. If it's non-zero, the event is re-queued
for processing in next event cycle. This can be used to prevent background
actions (hint: user commands) from hogging the CPU for too long time.

Huge changes. Neighbor and interface state machines rewritten.
It should be cleaner now, I'm preparing for file splitting.
Maybe I added some minor bugs. :-(

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.

Kernel route syncer supports multiple tables.
The changes are just too extensive for lazy me to list them
there, but see the comment at the top of sysdep/unix/krt.c.
The code got a bit more ifdeffy than I'd like, though.
Also fixed a bunch of FIXME's and added a couple of others. :)

Protocol engine bug fixes:
o Make proto_config->table always point to the right
table even if it should be the default one.
o When shutting down, kill protocol in reverse order
of their priority.
o When stopping a protocol down, disconnect it from
routing tables immediately instead of waiting
for the delayed protocol flush event.
Also added a protocol instance counter (used by KRT code
in very magic ways).

Cleaned up handling of interface patterns:
o Parsing of interface patterns moved to generic code,
introduced this_ipatt which works similarly to this_iface.
o Interface patterns now support selection by both interface
names and primary IP addresses.
o Proto `direct' updated.
o RIP updated as well, it also seems the memory corruption
bug there is gone.
