Add support for the atomic modesetting ioctl through a property-set API.
v1: Squashed intermediate patches from Ville, Rob and myself. Updated
for current kernel interface (no blobs).
v2: Rewrite user-facing API to provide transactional/cursor interface.
Use memclear to zero out ioctl.

v3 [Emil Velikov]: Remove DRM_CAP_ATOMIC - superseded by
DRM_CLIENT_CAP_ATOMIC.
Signed-off-by: Emil Velikov <emil.l.velikov@gmail.com>
Add a new API that allows the caller to skip any forced probing, which
may require slow i2c to a remote display, and only report the currently
active mode and encoder for a Connector. This is often the information
of interest and is much, much faster than re-retrieving the link status
and EDIDs, e.g. if the caller only wishes to count the number of active
outputs.
v2: Fix error path to avoid double free after a failed GETCONNECTOR
ioctl.
v3: Daniel strongly disapproved of my disjoint in behaviour between
GetConnector and GetConnectorCurrent, and considering how best to make a
drop in replacement for drmmode_output_init() convinced me keeping the
API as consistent as possible was the right approach.
v4: Avoid probing on the second calls to GETCONNECTOR for unconnected
outputs.

Unfortunately, there are some users of libdrm installed headers that like
to be built with -std=c89 -pedantic, which does not like "inline".
However, __inline works.

DRM_IOCTL_MODE_SETPLANE crtc_x, crtc_y are s32.
This is to allow a destination location that is partially off screen.
Make this more obvious to users of libdrm by using signed crtc_x/_y
parameters for drmModeSetPlane() as well.

The following minor changes were needed to these headers:
* Convert // comments to /* */
* No , after final member of enum
With these changes, these header files can be included by a program that
is built with gcc options:
