ccd4472e2a Add test_that_multisocketsink_and_socketsrc_preserve_meta
This test is in a seperate commit to the previous two because it depends
on and tests the functionality in both.

a297b0545f 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.

7c10499ecd 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`.

5b0ec93e99 tests: Add TCP pipelines test
There don't seem to be any unit tests for the socket handling elements.  As
I am about to attempt some refactorings I've added some basic tests which
exercise some of the happy-paths in tcpclientsrc, tcpserversrc,
tcpserversink and tcpclientsink.  They should let me know if I've caused
serious breakage.

They are far from exhaustive but are sufficient for me to have caught a few
memory-leaks in the existing code.
