Cycles: Rework the way how OpenCL devices are created

It was annoying copy-paste happened across OpenCL device constructor, device
enumeration and split kernel checks. Now those areas are using an utility
function which returns pairs of platform and device IDs for devices which are
supported by Cycles and enumeration is happening inside that list.

This makes it so filtering is happening in a single place, so there's no need
to keep 3 different functions in sync.

This commit also fixes a bug with wrong enumeration of devices caused by recent
fixes. Those fixes were in fact wrong and only happened to appear to be working
on laptop with optimus card on Linux. Root of those issues is in fact in bad
Linux driver for optimus cards.

Fix T45022: Update missing when linking objects with new depsgraph

Fix T45156: scaling region crash

Fix T45154: Translation binary file(blender.mo) for Japanese is too small

The issue was caused by some changes made to msgfmt which were needed to make
modified (cleaned-up, stripped-comments messages) working.

Unfortunately that fix was merged into the release branch, so this fix is to
be ported there as well and verified against rc1 translations.

Partial fix T45156: scaling region crash

'ar->winy' may not be initialized, making regions zoom in (past limits)
and attempt to draw very large text (~10x10k size characters), often crashing.

Fix isn't complete since it only corrects factory startup.

BGE Fix: apply velocity clamping on every physics subtick

This patch uses the Bullet "internal tick callback" functionality to
ensure that velocity clamping is performed after every physics update.
This makes a difference when physics subticks > 1, as in that case the
too-high velocity could have impacted the simulation.

This patch follows the examples at [1] and [2]; the latter example
also explains that the way we limit velocity in the BGE (before this
patch) is wrong.

Fix crasher when loading multiview OpenEXR image.

With multiview/multilayer OpenEXR file, `load_image_single()` will return NULL ibuf,
since it has already populated ima (with `image_create_multiview()` or
`image_create_multilayer()` calls).

Also, added some more checks before doing `IMB_ImBufFromStereo3d()`, to be sure
we do have enough slots in ibuf_arr, and we do not overwrite second ibuf either.

Fix T45204: String Splitting Function Bug: Using OpenEXR function even if compiled without OpenEXR.

Seriously!!!

Also, fix a potential buffer overrun here.

This should be backported to final release.

Cleanup: Fix a typo in world MIS.

Found by Lukas Stockner, thanks!

Revert "Fix off by one error in display of start/end frame in sequencer."

This reverts commit 0e02ad8b6495b2755598a24b487041a3ed8e0116.

Initial commit was done so visual result fits with animation cursor
in timeline but this makes it so it looks like one extra frame is
rendered. Other idea would be to render one less frame for sequencer
but this is not so nice either. Generally here's no way to be
fully consistent here, but at least let's be workflow-consistent

splash fix, previous had color conversion error

RNA: exposing image_user settings for ImageTextureNodes

This is required in order to access image sequence frame_duration and
frame_offset among other settings.

Fix T45051: Curve parent bug.

PARCURVE is deprecated parting type, should never have been exposed to user!

Not a regression, but safe enough for final 2.75 imho.

Missed changing default arg in addon_utils.disable

Fix T44320: UV island overlap considered linked

Fixed compilation error in editor/animation/anim_markers

Fix T45034: MirrorBall rendering on wrong camera axis

This was a mistake in the original code from D1079.

With the current way how direction ot mirror ball works camera should look
into negative Y direction. Corrected it in the camera matrix synchronization,
so no extra calculations are needed at the render time.

That's a bit annoying, but we'd better port it to the release branch, or
otherwise we'll end up with files created with wrong camera mapping after
2.75 release.

Fix T45145, multiview selection fix not working for scaled matrices.

Multiview code already accounts for scale, do not scale frame before
multiplying with matrix.

Fix T45144: Multi-value-edit ignored range

Fix camera stereo logic use /w regular select
