Fixes Oculus CV1 Lens Correction

OpenHMD update, disables OVRService upon starting the device, only when run with administrator.
Requires custom build of hidapi for now (github TheOnlyJoey/hidapi)

Use projection matrix from OpenHMD even if "Rotation from HMD" is disabled

Was actually applying IPD wrongly, should be correct now.

Merge branch 'master' into HMD_viewport

Draw additional viewport info in HMD view again (3D-cursor, mini-axis, etc)

On most (if not all) devices the stuff close to view borders won't be
visible because it's out of the field of view. Ideally we'd calculate their
positions based on the FOV, but that's for later.

Correction to previous commit, unset shader after session end

Also two other minor correcions.

Don't draw HMD view lens shader if session is not running

Fixup Python UI definition after lens shader removal

Refactor split-view drawing to make popups readable

Fix fragment shader compile error on Intel GPUs

Bunch of small HMD fixes, removed old now unused preferences

Merge branch 'master' into HMD_viewport

Conflicts:
source/blender/windowmanager/wm.h

Fixup for python UI definition

Fixes for HMD support windows build (thanks LazyDodo)

New OpenHMD 0.3rc version with PSVR, Oculus CV1 and better Vive tracking support.
Also introduces global shader, which will be adjusted based on the variables of the HMD drivers, this will make the manual selection of lens correction shaders obsolete, will be removed in next commit.

The hmd window is currently black before started (due to shader not having the hmd data yet), will be fixed as well.

Merge branch 'master' into HMD_viewport

Fix issues changing HMD device

Fix python UI for building without HMD

Disable OpenHMD dummy device for release builds

Also fixing warning.

Don't allow orthographic view in HMD view

Displaying camera in orthographic mode is still allowed. We don't want
to mess with render data and forcing perspective viewport rendering in
HMD view even if the camera is set to be orthographic might be
confusing.
