[media] v4l: kill the BKL
All of the hard problems for BKL removal appear to be solved in the v4l-dvb/master tree. This removes the BKL from the various open functions that do not need it, or only use it to protect an open count. The zoran driver is nontrivial in this regard, so I introduce a new mutex that locks both the open/release and the ioctl functions. Someone with access to the hardware can probably improve that by using the existing lock in all cases. Finally, all drivers that still use the locked version of the ioctl function now get called under a new mutex instead of the BKL.
