Add writeback support to modetest with the below options:
- Passing in -a -c will now also show the writeback connector
- Dump the writeback output buffer to bitstream
Usage: "./modetest -M msm -s <connector_id>:<widthxheight>
-a -o <filepath>
-P <plane_id>@<crtc_id>:<widthxheight>+0+0@RG24"
This currently supports single writeback connector.

Some of the helpers, such as the pattern drawing helpers or the format
lookup helpers, have potential to be reused. Move them into a separate
library to make it easier to share them.

The modetest application uses libkms to allocate dumb buffers, leading
to overallocation due to the hardcoded 32 bpp value. This can even cause
failures in drivers when the resulting pitch is too large for the
hardware to handle and gets rejected by the driver when creating the
frame buffer.
Fix this by computing the required bpp value and allocating dumb buffers
directly without going through libkms.

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

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.
