Fix Cycles stereo UI to follow (not even that) recent Blender changes

From review: add tooltips to convergence_mode
And add unique tooltip for viewport_distance

From review: replace some 'goto: monoview' with is_multiview_loaded

We still have the monoview_image and monoview_movie. It's easy to change them but I don't know, I find the code slightly more clean by using it :/

Move 'Update Views' to the _ex panel, and fix crash on update routine

Merge remote-tracking branch 'origin/master' into multiview

Small cleanup (int to bool)

From review: better error message when active camera is not multi-view

From review: left over from Dr. Epilepsy mode removal

Fallback to the zero ibuf, not the last one

Cleanup: minor edits

Cleanup: headers, minor edits

Support for building without EXR

Cleanup: minor edits

drawcamera_stereo3d had shadowed 'scale' var, rename to make unique

stereoimbuf: replace array with struct since index lookups

Index access weren't used anywhere and made it a little harder to follow.

Correct bool/flag use

Cleanup: imbuf API

use extra arg for IMB_ImBufFromStereo which used the first argument for both input and output.
also no need to use pointer-to-pointer in function body.

Cleanup: API naming - use BKE_scene_multiview_*** prefix

Cleanup: API naming - use BKE_camera_multiview_*** prefix

Cleanup: remove redundant casts, vars

some odd expressions:
"(RenderView *)(&rr->views)->first" -> "rr->views.first"

Cleanup: warning
