media: videodev2.h: add V4L2_FMT_FLAG_CONTINUOUS_BYTESTREAM

Browse source

Add an enum_fmt format flag to specifically tag coded formats where
full bytestream parsing is supported by the device.

Some stateful decoders are capable of fully parsing a bytestream,
but others require that userspace pre-parses the bytestream into
frames or fields (see the corresponding pixelformat descriptions
for details).

If this flag is set, then this pre-parsing step is not required
(but still possible, of course).
