Currently we have separated sources of standard DV cameras and HDV cameras even
though they share a lot of common code.

Using the AV/C probing mechanism, one can detect a connected device's output
format, we should therefore:
* unify hdv1394src/dv1394src code
* detect that format before going to PAUSED
* properly set the output caps and code path according to the detected format.

The changes required can be seen in this commit from dvgrab:
