This fixes warnings for weston-debug, input, compositor, log and
linux-explicit-sync. Warnings range from swapping '[in]', '[out]' with
the function arguments to wrong parameter names.

As of the previous commit, we never create state which uses overlay
planes on non-atomic drivers. We can thus remove the calls to
drmModeSetPlane.
The only time we ever waited for vblank events was when we had called
drmModeSetPlane and needed to make sure we waited until it was active.
We can thus also remove all the vblank event machinery.

Without atomic modesetting, we have no way to know whether or not our
desired configuration is usable. It might fail for a number of reasons:
scaling limits, bandwidth limits, global resource (e.g. decompression)
unit contention, or really just anything.
Not only this, but there is no good way to ensure that our configuration
actually lands together in the same refresh cycle - hence the 'atomic'
in atomic modesetting. Some drivers implement a synchronously blocking
drmModeSetPlane, whereas others return immediately. Using overlay planes
can thus decimate your framerate.
The pre-atomic API is not extensible either, so we need numerous out
clauses: fail if we're cropping or scaling (sometimes), or changing
formats, or fencing, or ...
Now we've had atomic support stable for a couple of releases, just
remove support for doing anything more fancy than displaying our
composited output and a cursor with drivers which don't support atomic
modesetting.
Support for using overlay planes was already disabled by default when
using the legacy API, and required a debug key combination to toggle it
on by flipping the sprites_are_broken variable. We can ensure that we
never try to use it on legacy by simply ignoring the hotkey when in
legacy mode.

When using logind launcher, we receive a PauseDevice "gone" message
from logind session management for each device we close while looking
for KMS devices.
Make logind notify the backend of the device add/remove so that the
backend can decide what to do, instead of assuming that if it is a
DRM_MAJOR device the session should be (de)activated. The backend can
then react to its specific device.
Fixes#251

A output repaint loop isn't scheduled beacuse the output repaint_status
is AWAITING_COMPLETION when dmps is turned off in update_complete().
Therefore, the display attached to the output is remain inactive even if
weston wakes up. By going through finish_frame, the output
repaint_status is fixed to correct status.

Move the DRM-backend into a new sub-directory to make it stand out from
libweston core. This facilitates splitting drm.c into more files later.
vaapi-recorder is used only by DRM-backend, move that too.
libbacklight is used only by DRM-backend and a manual test program, and is
moved as well.
