V4L/DVB (11096): V4L2 Driver for the Hauppauge HD PVR usb capture device

The device encodes component video up to 1080i to a MPEG-TS stream with
H.264 video and stereo AAC audio. Newer firmwares accept also AC3
(up to 5.1) audio over optical SPDIF without reencoding.
Firmware upgrade is unimplemeted but rather unimportant since
the firmware sits on a flash chip.

The I2C adapter to drive the integrated infrared receiver/sender is
currently disabled due to a conflict with cx18-based devices.
