means the data size of a frame can be calculated if the dimensions
are known.
* calculate frame data sizes for uncompressed formats instead of believing
what the hardware says. the UVC spec changed between 1.0 and 1.1, and
as a result, some devices return bogus information.
* skip under-sized as well as over-sized uncompressed frames; there is
only one correct size for uncompressed frames.
* remove quirk to fix uncompressed frame sizes on certain devices,
since that now always happens.
* check that the device is actually using the parameters we think it's
using.

equivilent. only define one structure, struct usb_video_frame_desc,
and handle both types of frame descriptors in the same code.
* replace hardcoded numbers with 'sizeof(struct usb_video_frame_desc)'
where the numbers represent the size of a frame descriptor

as it can be and don't define the following members.
* reenable control support for devices where bControlSize != 2 in
the processing unit descriptor.
tested on alpha, amd64, i386, sparc64 and zaurus, as well as the machine
where previous support for variable bControlSize caused a hang.

alive during match and attach. do not attempt to reuse this pointer or
ifaces during a deferred attach routine, since it will contain junk,
but instead make copies.

Also those devices have a own stream header procotol for which we've
added a seperate stream header decode function, which does not work yet.

"fragment" gets replaced by "sample".
"sample" gets replaced by "frame".
A sample is a peace of a frame (final image). No functional changes.

field is unreliable and can start with any number. Use an own internal
array index instead.
- If the read buffer is too small, return a propper error to the calling
functions. Just check the buffer size if we use the read(2) method since
it doesn't affect mmap(2).
Fixes kernel crashes seen with the M$ LifeCam NX-6000 and internal
(laptop) Sonix chipsets.
Tested by jcs@ (Sonix) and myself (NX-6000).

meantime, the memory allocation for the read(2) method for video(4)
is not right anymore, and can cause a buffer overflow.
We fix this by queuering the maximum available image size for a device at
attach time. If the image size should exceed our video(4) buffer after a
video format change (which shouldn't happen), uvideo(4) will gracefully
fail.

VIDEO_S_FMT doesn't exactly match the devices available resolutions,
return the next best matching resolution which we have.
Makes some V4L2 apps happy when running them with the default resolution
(no options).
