[package] add package for BIRD Internet Routing Daemon

Here is the patch that adds a package for The BIRD Internet Routing
Daemon. It is updated to the current version of BIRD (v 1.2.2).

BIRD is an internet routing daemon that implements OSPF, RIP and BGP.
It is fast, lightweight and small (cca 300 kB), therefore ideal for
OpenWRT based routers.

The makefile is rather tricky, as BIRD have to be built two times  (for
IPv4 and IPv6 versions) and there are separate packages for BIRD daemon
and BIRD client, because client depends on libreadline and is not
strictly necessary.

+BIRD is an internet routing daemon which manages TCP/IP routing tables
+with support of modern routing protocols, easy to use configuration
+interface and powerful route filtering language. It is lightweight and
+efficient and therefore appropriate for small embedded routers.
+
+endef
+
+define Package/bird/Default/description2
+In BGP, BIRD supports communities, multiprotocol extensions, MD5
+authentication, 32bit AS numbers and could act as a route server or a
+route reflector. BIRD also supports multiple RIBs, multiple kernel
+routing tables and redistribution between the protocols with a powerful
+configuration syntax.
+
+endef
+
+define Package/bird/Default/description3
+This is a BIRD command-line client. It is used to send commands to BIRD,
+commands can perform simple actions such as enabling/disabling of
+protocols, telling BIRD to show various information, telling it to show
+a routing table filtered by a filter, or asking BIRD to reconfigure.
+
+Unless you can't afford dependency on ncurses and readline, you
+should install BIRD command-line client together with BIRD.
