Not only the qx3 microscope has a button, but some cameras too. Tested
with the Trust sp@cecam 100 (and with a creative and ezcam without button).

Having a framerate divisor of 3 is not really necesarry and leads to
various troubles (frames going missing, compression issues) when allowed.

This is a complete rewrite of the old v4l1 vicam subdriver, featuring
multiple resolutions, gain + exposure control and still has less code.
Oh and it is a v4l2 driver rather then v4l1 ofcourse :)
Many thanks to Devin Heitmueller <dheitmueller@kernellabs.com> for
donating his 3com homeconnect to me, which made this rewrite possible.

Tested with a camera with usb-id: 0c45:62bb
Also enable dmi based flopped laptop detection for the 0c45:627b ov7660 model.
Some of the MSI laptops with upside down camera have this one instead of the
0c45:624f.

During image capture, the filling rate of the isoc packets is computed.
It is then used by a work queue to update the current JPEG quality.

A marker 'ff ff 00 c4 c4 96' indicates an end of frame.
It is 62 bytes long and may be splitted on 2 packets.
It contains a flag 'USB full' which indicates that the frame is truncated.

The infrared was set by sensor write instead of bridge GPIO.
It is now settable by the standard control ILLUMINATOR_1.
A module parameter permits to set the right GPIO bit according

Looking at the windows inf file, for usb ids with a sensor type where probing
is needed to determine the type (for example ov7630 or soi768), this is
needed for all bridge variants with a usb id indicating this sensor type.
So do the probing to determine the actual sensor type for types where the
usb-id info is not 100% deterministic, independent of the bridge type.
If you look through the list of currently active usb ids in sonixj, this
effectively only changes the code path for 0c45:60fe (sn9c105 + ov7630) and
0c45:612e (sn9c110 + ov7630), which according to the inf file can have a
soi768 instead of a ov7630 just like the sn9c120 + ov7630 models where we
already probe for a soi7630.
The main reason for this code change is to keep the code paths as bridge
variant independent as possible, so that we don't need a lot of special
per bridge cases, as we enable more usb-ids in the future.
This change makes the 0c45:60fe code path identical to the successfully
tested 0c45:613e, so also make sonixj the default driver for 0c45:60fe.

Both we and the windows driver make no sensor specific differences
(with some exceptions) for different sonixj bridge types. Thus if a
sn9c105 bridge has been successfully tested with a sensor, the same
sensor can be successfully used with a sn9c120 bridge too.
Using this knowledge we can move over most usb-ids too the sonixj
driver when both are compiled.

Now that our bridge code is unified for sn9c101/102 and sn9c103 models,
the sn9c103 models should simply work, given that the only difference
in the sn9c103 is audio support and a gamma correction table.
