Patch containing the new nanomsg plugin + pipeline check + docs

Nanomsg (http://nanomsg.org/) is a socket library and the spiritual successor
to ZeroMQ (http://zeromq.org/). It provides several communication patterns
(push-pull, publish-subscribe etc.) and transport mechanisms (IPC, TCP,
inter-threads).

This patch adds a GStreamer plugin that contains one nanomsgsrc and one
nanomsgsink element. These sources/sinks can transmit generic data over nanomsg
SP sockets.

One noteworthy feature of nanomsg sockets is that receivers can start before
senders, and if either the sender or the receiver goes away and returns later,
the connection is transparently reestablished. This is useful for ensuring that
crashing senders and/or receivers don't permanently sever the connection.
Combining it with the GST RTP payloader with a nonzero config interval makes
sure playback on the receiver's end can automatically continue.
