Integrate SoC work done by Alessandro for the Freevo project.
Adds cam support to the dvb stack in GStreamer and a new
element (actually a bin) called dvbbasebin that integrates
dvbsrc and mpegtsparse to a) handle decryption and b) allow
acquiring multiple channels on same transponder without
knowing pid numbers.
