bird2: add new package

BIRD is an internet routing daemon with support of modern
routing protocols (BGP, OSPF, RIP, Babel) for IPv4 and IPv6. This is
the 2.x branch.

Moved from the openwrt/routing feed, as discussed in
https://github.com/openwrt/routing/issues/184.

+define Package/bird2/Default/description
+  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/bird2/description
+  $(call Package/bird2/Default/description)
+
+  BIRD supports OSPFv2, RIPv2, Babel and BGP protocols for IPv4 and
+  OSPFv3, RIPng, Babel and BGP protocols for IPv6.
+
+  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.
+
+  This is the 2.0 branch of Bird which integrates support for IPv4 and IPv6
+  into a single branch, and also adds support for the Babel routing protocol.
+endef
+
+define Package/bird2c/description
+  $(call Package/bird2/Default/description)
+
+  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.

+
+define Package/bird2cl/description
