gstdtcpip and lib_dtcpip

A DTCP (Digital Transmission Content Protection) element is needed to interface
to a private DTCP/IP decrypting library to handle encrypted (link protected)
content from a DTCP/IP enabled DLNA (Digital Living Network Allicance) server.

This enhancement issue holds the patches for a gstdtcpip element that is part
of the dlnasrc bin.

The dtcpip element will not actually perform decryption.  DTCP is governed by a
specification that is managed by DTLA (www.dtcp.com) and only member
organizations can access the spec and produce implementations.  This solution
abstracts the actual DTCP stack via an API that is accessed by making function
calls to runtime-loaded DSO.  The intention is to provide a GStreamer element
that extends decryption capability once a proprietary DTCP library
implementation is referenced by the appropriate environment variables.

The dtcpip element does not autoplug, but rather gets plugged in by the
dlnasrc.  There was controversy over this as described in issue #709455.
