Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.

Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.

The inode argument was never used. Removing it from video_usercopy
brings the function pointer type of video_usercopy in line with similar
v4l2 functions, thus simplifying several drivers.

Remove the priv field and let video_get/set_drvdata use dev_get_drvdata
and dev_set_drvdata instead.

Convert all drivers that still used priv directly.

Set the length of the v4l2 buffer to the length of the mapped memory.

This should fix the problem with amsn.

The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly.  To work around
this, makefiles would define some new macro based on the setting of a
config variable.  e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary.  This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.
