Streaming using mmap didn't work in the VIU driver. We need to
start/stop DMA in streamon/streamoff and free the buffers on
release. Add appropriate driver extension now.

'n' may be bigger than MAX_INT*sizeof(int), if so checking of truncated
(int)(n/sizeof(int)) for LIRCBUF_SIZE overflow and then using nontruncated 'count'
doesn't make sense. Also n may be up to sizeof(int)-1 bytes bigger than expected,
so check value of (n % sizeof(int)) too.

This is the core of the WL1273 FM radio driver, it connects
the two child modules. The two child drivers are
drivers/media/radio/radio-wl1273.c and sound/soc/codecs/wl1273.c.
The radio-wl1273 driver implements the V4L2 interface and communicates
with the device. The ALSA codec offers digital audio, without it only
analog audio is available.

Our old start of frame detection code wrongly assumes that the sof
marker always lives at the beginning of the frame. At least for the
0c45:602a camera this is not the case. This patch also improves
the framerate from 28 fps to 30 fps with the 0c45:6005 and 0c45:6007

Support for mt9m001 (mi1300) is broken:
- Table is incomplete;
- Only one resolution is currently supported by the driver;
- Resolution is incomplete;
- it complains about broken JPEG headers.
Use the same init found on em28xx driver, and properly report the
output format as 8-bits GRAY.

Changeset 35680ba broke several devices:
- Sony Playstation Eye (1415:2000);
- Gigaware model 25-234 (0c45:628f);
- Logitech Messenger Plus (046d:08f6).
Probably more devices were broken by this change.
What happens is that several devices don't need to save some bandwidth
for audio.
Also, as pointed by Hans de Goede <hdegoede@redhat.com>, the logic
that implements the bandwidth reservation for audio is broken, since
it will reduce the alt number twice, on devices with audio.
So, let's just revert the broken logic, and think on a better solution
for usb 1.1 devices with audio that can't use the maximum packetsize.

I found that the problems people have reported with the USB-TV-stick
"Terratec Cinergy Hybrid T USB XS" (USB-ID: 0ccd:0042)
are coming from a wrong header file in the v4l-sources.
Attached is a diff, which fixes the problem (tested successfully here).
Obviously the USB-ID has been associated with a wrong chip: EM2880
instead of EM2882, which would be correct.

This patch adds a loopback driver to rc-core which I've found useful for
running scripted tests of different parts of rc-core without having to
fiddle with real hardware.
Basically it emulates hardware with a learning and a non-learning
receiver and two transmitters (which correspond to the two
receivers). TX data that is sent is fed back as input on the
corresponding receiver, which allows for debugging of IR decoders,
keymaps, etc.

The RC5 old decoder used custom_irq to indicate the need of handling
the IRQ on a different way. Instead of doing it, let the core just call the
bttv input IRQ handler, and add the code there to call the legacy decoder.
While here, remove the gpioq waitqueue, as this is not used anywhere, and
add a debug msg to help removing the legacy RC5 code.
