Shorter and more in line with our general igt_ prefix for everything
which isn't somehow intel or i915-gem or otherwise hw specific - these
helpers here are all fully generic framebuffer handling functions
based on kms + cairo.
Well, the actual buffer alloc is done with i915 gem, but meh ;-)
Two special cases:
- bpp_depth_to_drm_format and drm_format_to_bpp completely lacked
prefixes, so just add igt_.
- write_fb was a bit misleading given that we have gem_write for
uploading to buffers. Rename that to write_fb_to_png to make it
crystal clear what this thing does even without looking at docs.

Use the new-style function using drm fourcc codes instead everywhere.
To easily use thew fourcc based interface also expose
bpp_depth_to_drm_format from the library. Finally include drm_fourcc.h
from the igt_kms.h header since pretty much everyone needs this now.

Functions which provide feature checks through igt_skip should be of
the form <prefix>_require_<feature>.
Otoh feature checks which return in a boolean whether the feature is
available should be of the form <prefix>_has_<feature>, e.g.
gem_has_blt.
