Patch proposal for adding Unix domain socket support

I've written separate unix{server,client}{sink,src} elements in
gst-plugins-base/gst in the Git repo. The draft patch should be attached with
this post. To apply it, I do simply:
$ cd gst-plugins-base
$ git apply gst-unixsockets.patch

I used the similar tcp* element code as a template. Here is some notes what has
been essentially changed and what's kept:
- unixserversink does not inherit multifdsink, but will only send to one client
  - multifdsink depends too much on TCP-specific code
  - if multifdsink is needed, fallback to gsttcpserversink?
- examples use 'socat' tool as the other end point for the connection
- supports raw data transfer and GDP protocol (type of SOCK_STREAM)

I'm not entirely sure if the elements are handling broken pipes and closed
connections correctly, but the behavior is somewhat similar to the tcp
counterparts (shutting down pipeline via error checking).

Comments are appreciated and I can make further changes if necessary.
