Cleanup: UI layout: remove unsed and confusing parameter.

Things are complicated enough like that, no need to add useless noise on
top of it!

Normal edit modifier: Fix relation builder for the new dependency graph

Ammend to rB00dc0666b3fe: forgot to fix boid->ground of first particle.

This code is confusing, such dirty details should not sneak out of
particles' own private code. :(

Fix T49631: radial control operators not using DPI properly.

Fix T49640: Cycles constant folding incorrect for texture coordinates.

Fix T49636: material draw mode crash with displacement and missing group input node.

Cycles: Get rid of ifdef-ed noinline policy

Cycles: Fix use of uninitialized variable in SSS

When ray hits curve segment with SSS shader it was possible to have
uninitialized hit_P variable used for sampling.

Seems that was a reason of our headache of difference between AVX2
and SSE4 render results here, so now we can revert all the nasty
ifdef-ed inline policies.

Fix T49622: Grease pencil not rendering out of VSE

Fix T49502: file browser on OS X not highlighting external drives.

Fix T49629: Graph editor normalize function doesn't work on f-curves with a constant key value

Technically it is a regression in behavior and should be 2.78a.

Make console message more clear for --scene argument

Fix T49623: Immediately crash trying to render attached file in Cycles

Original fix in this area was not really complete (but was the safest at
the release time). Now all the crazy configurations of slots going out
of sync should be handled here.

Fix viewport camera gets out of sync in certain cases

It was possible to have two viewports opened and start using Ctrl-0
to make different objects an active camera for the viewport. This
worked fine for viewports which had decoupled camera from the scene,
but if viewport was locked to scene camera it was possible to run into
situation when two different viewports are locked to scene camera but
had different v3d->camera pointers.

Fix T49609: Point density textures: vertex colors are not properly averaged in BI

Nice to have in 2.78a, though not a regression.

Fix T49608: runtime-only particle's boid->ground Object pointer was left dangling to invalid value in read code...

Fix a few compile errors with C++11 on macOS.

BLI_task: fix case were some pool could work in more threads than allowed.

We were checking for number of tasks from given pool already active, and
then atomically increasing it if allowed - this is not correct, number
could be increased by another thread between check and atomic op!

Atomic primitives are nice, but you must be very careful with *how* you
use them... Now we atomically increase counter, check result, and if we
end up over max value, abort and decrease counter again.

Spotted by Sergey, thanks!

Cycles: Fix OpenCL split kernel compilation after recent CUDA 8 performance fix

Datablock management: remove 'proxy_from' pointer from 'is ID used' checks.

Pretty much same reason as for the 'from' pointer of shapekeys - runtime
data creating loops and 'ghost' dependencies between datablocks.

We need to handle them in cases like remapping, but whall not take them
into account to check dependencies between datablocks... :/
