Broadcom CrystalHD decoder support
This new module works with BCM70015 Crystal HD video decoders It handles hardware decoding of H264, VC-1 and mpeg2 So far, it only works on GNU/Linux with the appropriate driver and library. Windows version is still limited. This is the first part, since mpeg4, interlaced and BCM70012 are not working yet.
