Since HWC2 doesn't require the use of threads to implement correct
synchronization, remove some of these threads.

This patch adds a worker which listens to drm events. If the
drm event has a handler associated with it, the listener will
call the handler.

- deleted private copy constructors
- replace delete with unique_ptr
- use in-class assignment
- remove default constructors/destructors when no longer needed
- remove most iterators used in for loops
- move UniqueFd to its own header so drmresources can use it

This patch queues modeset in the compositor for application on
the next frame. This allows us to perform the modeset atomically
with the first frame that comes in after the mode is changed.

Use the new drm blob ioctl and atomic modeset properties to
do atomic modesetting, as opposed to the old setCrtc call.
This allows us to set timing as soon as the system layer requests
a new active config, as opposed to delaying it until we have
an fb. Aside from reducing complexity, this should help with
event control requests as we'll be able to service them with
hw vblanks instead of synthesized sleeps.

Replace the basic, single overlay, modeset/flip implementation with
a new Compositor instantiation for drm. The new compositor uses the
drm atomic interface to composite layers to multiple hardware planes.
This change also introduces an importer argument in
Compositor::CreateComposition. By specifying the importer, Compositor
instances are responsible for cleaning up buffer objects submitted
via Composition::AddLayer.

This allows us to compartmentalize a bunch of code/logic from
hwcomposer.cpp into drm classes.
