OMAP buffers are mapped to userspace in write-combining mode by default.
Add support for cached mappings.

The library is just a wrapper around ioctls. It doesn't provide much
value, and its API is marked as experimental and should thus not be
expected to be stable. As third party library dependencies are always
painful for distributors and packagers, use the ioctls directly for now.

The Crtc::get_primary_plane() method returns the first primary plane
that supports the CRTC. While being correct, this could lead to multiple
primary planes being associated with the CRTC, which can confuse
applications. To avoid that, return insead the primary plane already
associated with the CRTC if one exists, otherwise keep the current
behaviour.

Add OmapCard and OmapFramebuffer classes to utilize omap_bos. Only
non-tiled framebuffer is implemented for now.

Add a base MappedFramebuffer class, which inherits Framebuffer and
implements IMappedFramebuffer. This helps to implement platform
specific framebuffer classes, like OmapFramebuffer.

This enables write access to the dumb fb with mmap().

Change calculated_vrefresh to round to 2 decimals, and do two rounds
when looking for a mode: first look for exact vrefresh match, then look
for rounded match.

Enable set/get for sync polarities and interlace. Add
videomode_from_timings() helper to construct Videomode from non-X
timings.

Note colorbar does not support 24 bit modes (RGB888 or BGR888) yet.
|
|
Object types can have different properties with the same name, so we
need to move name-based property lookup from Card to DrmPropObject.

4fb69b7d20e90746855de122422ac9cabd78f66f ("kms++: use DrmPropObject in
AtomicReq") made AtomicReq::add() use a not-yet-implemented method.
Fix this by changing that line back.

The objects to which we set properties with AtomicReq must have
properties, so they are DrmPropObjects instead of DrmObjects.

Sort the declarations and add DrmPropObject.
