To prepare for storing more information about pixel formats in
PixelFormatInfo, move the class to formats.cpp and document it. The
pixel formats database is moved to the same file, and a new static
function is added to PixelFormatInfo to retrieve a PixelFormatInfo for a
PixelFormat.

Add a new class to hold format information for V4L2 devices and
subdevices. The object describes the relationship between either pixel
formats (V4L2 devices) or media bus codes (V4L2 subdevice) and a list of
image sizes which can be produced with that format.
