bird3: 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 3.x branch, a multithreaded rewrite.

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

+define Package/bird3/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/bird3/description
+  $(call Package/bird3/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 3.0 branch of Bird which is a multithreaded rewrite.
+endef
+
+define Package/bird3c/description
+  $(call Package/bird3/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.

+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We don't want birdc to write its history file to flash, so hard-code the
+history file to /var/tmp instead.
