Multiple the image height by 1.5 for NV12/NV21 and by 2 for NV16/NV61 to
make room for the chroma plane.

The line stride passed to the function is expressed in bytes, there's no
need to multiply it by 2.

Enable all standard automake warnings except for -Wpointer-arith (as the
test pattern generation code uses void pointer arithmetics) and fix
them.

YUV420 support is trivial to add since the code already supports
YVU420.
But it looks like the YVU420 support is a bit broken. The chroma
planes are passed in the wrong order to the fill functions, so
fix that while were at it.

The fourcc is inside the format_info structure, so if we want to use
it inside the various fill_tiles functions, we need to pass down the
whole format_info, not just the rgb/yuv infos.

libkms only has the xrgb8888 format, so we're overallocating the bo by
quite a lot in some cases. But we still need to get the pitch from the
libkms since it's the driver that decides how to align it.

As the modeset test application is often referred to as an example of
the KMS API usage, move test pattern generation and buffer allocation to
a separate file to keep it simple and clear.
