Many video drivers implement a fixed set of frame formats and thus face a task
of finding the best match for a user-requested format. Implementing this in a
generic function has also an advantage, that different drivers with similar
supported format sets will select the same format for the user, which improves
consistency across drivers.

The old usbvideo ibmcam driver needs to be replaced with a v4l2 driver
preferably using the gspca webcam framework rather then the old usbvideo
framework.

This new gspca sub driver sets a first step in that direction. The ibmcam
driver supports 4 different model webcams. This new driver (for now) only
supports Model 3 cameras, as my test cam is a Model 3 cam, or so I thought.

Upon reading:
http://www.linux-usb.org/ibmcam/
I learned that the IBM Netcamera Pro I have even though having the same
usb id and the same bcd version is different from the Model 3 cameras
supported by the ibmcam driver. So this new gscpa subdriver supports Model 3
cameras (untested), and the IBM Netcamera Pro. Currently use with the
IBM Netcamera Pro requires a module parameter. I hope to be able to
autodetect which is which in the future.

This flag is intended to indicate streaming errors, which might have
resulted in corrupted video data in the buffer, but the buffer can still
be reused and streaming may continue.

Setting this flag and returning 0 is different from returning EIO. The
latter should now indicate more serious (unrecoverable) errors.

This patch also solves a problem with the ioctl handling code in
vl42-ioctl.c, which does not copy buffer identification data back to the
userspace when EIO is returned, so there is no way for applications
to discover on which buffer the operation failed in such cases.

This adds the above APIs to the v4l2 core. This is based on version v1.2
of the RFC titled "V4L - Support for video timings at the input/output interface"
Following new ioctls are added:-

        - VIDIOC_ENUM_DV_PRESETS
        - VIDIOC_S_DV_PRESET
        - VIDIOC_G_DV_PRESET
        - VIDIOC_QUERY_DV_PRESET
        - VIDIOC_S_DV_TIMINGS
        - VIDIOC_G_DV_TIMINGS

Please refer to the RFC for the details. This code was tested using vpfe
capture driver on TI's DM365. Following is the test configuration used :-

Blu-Ray HD DVD source -> TVP7002 -> DM365 (VPFE) ->DDR

A draft version of the TVP7002 driver (currently being reviewed in the mailing
list) was used that supports V4L2_DV_1080I60 & V4L2_DV_720P60 presets.

A loopback video capture application was used for testing these APIs. This calls
following IOCTLS :-

 -  verify the new v4l2_input capabilities flag added
 -  Enumerate available presets using VIDIOC_ENUM_DV_PRESETS
 -  Set one of the supported preset using VIDIOC_S_DV_PRESET
 -  Get current preset using VIDIOC_G_DV_PRESET
 -  Detect current preset using VIDIOC_QUERY_DV_PRESET
 -  Using stub functions in tvp7002, verify VIDIOC_S_DV_TIMINGS
    and VIDIOC_G_DV_TIMINGS ioctls are received at the sub device.
