tcp: Add element socketsrc `socketsrc` can be considered a source counterpart to `multisocketsink`. It can be considered a generalization of `tcpclientsrc` and `tcpserversrc`: it contains all the logic required to communicate over the socket but none of the logic for creating the sockets/establishing the connection in the first place, allowing the user to accomplish this externally in whatever manner they wish making it applicable to other types of sockets besides TCP. This commit essentially copies the implementation directly from tcpserversrc. Later patches will tidy the implementation up and re-implement `tcpclientsrc` and `tcpserversrc` in terms of `socketsrc`. See https://bugzilla.gnome.org/show_bug.cgi?id=739546

socketsrc: handle GstNetworkMessage events Add a property to handle GstNetworkMessage events. These events contain a buffer that is sent on the socket to allow for simple bidirectional communication.

socketsrc: Add `connection-closed-by-peer` signal This provides notification that the socket in use was closed by the peer and gives an opportunity to replace it with a new one which is not closed, allowing reading from many sockets in order. I use this in pulsevideo to implement reconnection logic to handle the pulsevideo service dieing, such that is can be restarted without disrupting downstream.
