V4L/DVB (3693): Fix msp3400c and bttv stereo/mono/bilingual detection/handling
- msp3400c did not detect the second carrier, thus being always mono. - properly mute the msp3400c while detecting the carrier. - fix checks on the presence of scart2/3 inputs and scart 2 output. - implement proper audio mode fallbacks for msp3400c/d, identical to the way msp3400g works. - MODE_STEREO no longer produces dual languages when set for a bilingual transmission, instead it falls back to LANG1. Use LANG1_LANG2 to hear both languages of a bilingual transmission. This is much more intuitive for the user and is in accordance with the preferred usage in the v4l2 specification. - bttv tried to implement v4l2 calls with v4l1 calls to the i2c devices, completely mangling the audmode/rxsubchans handling. v4l2 calls now do v4l2 calls to the i2c devices. - fixed broken i2c_vidiocschan in bttv. - add start/end lines to LOG_STATUS.
