In order to remove the logic for detecting supported shared
pixmap formats from device models, make qemu_default_pixman_format()
capable for failing by returning 0 which is not a possible format
value rather than asserting.

Helper function to map qemu colors (32bit integer + matching PixelFormat)
into pixman_color_t.

Remove an unnecessary mutual inclusion loop between qemu-pixman.h and
console.h, since the former was only including the latter for
'PixelFormat*', which can be provided by typedefs.h. This requires a
minor adjustment to the files which included qemu-pixman.h, since
they were relying on it implicitly dragging in all of console.h.
