Cycles: Remove explicit std:: from types where possible

We have our own abstraction level on top of the STL's implementation.
This commit will guarantee our tweaks are used for all cases.

Blender 2.78: Port style cleanup from Cycles

Kinda nice to have official release code to be really clean.

Fix T49827L Crash linking material while in Material viewport shading mode

Material linking might and does change the way how drawObject is calculated
but does not tag drawObject for recalculation in any way.

Now use dependency graph to tag draw object for reclaculation. Currently do
this using OB_RECALC_DATA taq since tagging is not very granular yet. In the
future we can introduce ore granular tagging in the new dependency graph
easily.

Simple and safe for 2.78a.

Fix T49818: Crash when rendering with motion blur

It was possible to have non-initialized unaligned BVH split
to be used when regular BVH split SAH was inf. Now we ensure
that unaligned splitter is only used when it's really initialized.

It's a regression and should be in 2.78a.

Cycles: Cleanup, spaces

Fix T49764: Audio strips crackle when animating the volume

- Implemented linear interpolation for volume changes in the software
mixer.
- Using this in the software device.

Fix T49750: Cycles wrong ray differentials for perspective and stereo cameras.

Fix T49793 : Fix enabling SSE2 globally for msvc.

When feeding msvc both /arch:sse2 and /arch:sse it's not smart enough to pick the best option, just goes with the last option

Fix mistake in BKE_mesh_new_from_object handling of materials in MetaBall case.

Typo, spoted by Coverity scan.

To be backported to 2.78a.

Fix T49656: Crash when starting playback while using JACK audio with A/V sync

When ED_screen_animation_play is called from wm_event_do_handlers,ScrArea *sa = CTX_wm_area(C); is NULL in ED_screen_animation_timer.
Informing the audio system in CTX_data_main_set, that a new Main has been set.

Cycles: use near clipping distance in panorama camera.

Fix T49797: Exception from scene update handler might leak external engine descriptors

This was causing memory leaks in Cycles.

Some more detailed information in the comment in the code.

Seems to be safe and nice enough for 2.78a.

Fix T49789: Compositor mix node interpolation bug

Blender 2.78a release: Use proper "a' on the splash

Blender 2.78a release: Update addons submodule hash

Fix T49775: Appending data with internal dependency cycles prevents correct clearing of linked data-blocks.

This is not a simple fix, but imho still needs to be backported to 2.78a...

[windows] Create A Blender Desktop Shortcut in the msi installer , fixes T49522

Fix T49722: Appending Bug (Groups).

One day we'll have to reconsider why some many 'real' ID usages are not
refcounting... :(

To be backported to 2.78a.

Fix T49738: Hair Add Brush doesn't work

the issue was caused by wrong default value for brush particle count
which was clamped on display from 0 to 1. This is technically a regression
but how to port this to 2.78a?

Fix missing outliner redraw when adding VSE strip

Needed for outliner "Sequence" display mode.
