Pass workspace for space listeners

Space Image needs this to get active layer to get active object.

Workspace: "use_scene_settings" flag

This option determine whether we get the engine, layer and render settings
from the workspace or from the scene.

It is useful to allow for quick preview of the final render (F12) while in
a workspace,

Cycles: Attempt to work around compilation of sm_20 and sm_21

Disabled forceinline for those architectures, which seems to be compiling
successfully more often.

There might be ~3% slowdown based on quick tests, but better be rendering
something rather than failing to compile kernels again and again.

Those architectures will be doomed for abandon once we'll switch to toolkit 9.

Fix T52628: own error in string duplication

Error in 636baa598a56

Cycles: disable fast math flags, only use a subset.

Empty BVH nodes are set to NaN which must be preserved all the way to the
tnear <= tfar test which can then give false for empty nodes. This needs
strict semantices and careful argument ordering for min() and max(), so
the second argument is used if either of the arguments is NaN.

Fixes T52635: crash in BVH traversal with SSE4.1.

Fix: Grease Pencil pie menu keymaps were broken after the menus got renamed

Cycles: Safer fix for infinite recursion

Previous fix wasn't working correct for certain compiler and CPU intrinsics
mode, causing quite some crashes.

This should be a safer fix, which is closer in behavior to previous release
but which should still fix issues with robust curve intersection.

Fix T52650:Grease pencil selection its not automatically updating in Clip Editor

Math Lib: normalized vector project functions

Fix T52149: LoopTriArray computation was not correctly protected against concurrency.

Note: this commit seems to work as expected (also with transform
snapping etc.). However, it is rather unsafe - not enough for 2.79 at
least, unless we get much more testing on it. It also depends on three
previous ones.

Note that using a global lock here is far from ideal, we should rather
have a lock per DM, but that will do for now, whole DM thing is doomed
to oblivion anyway in 2.8.

Also, we may need a `DM_DIRTY_LOOPTRIS` dirty flag at some point. Looks
like we can survive without it for now though... Probably because cached
looptris are never copied accross DM's?

Cleanup: remove useless `DM_ensure_looptri()`.

That one was doing exactly same thing as `dm->getLoopTriArray()`, no
point in having twice the same code here...

Fix transform snap code using 'allocated' flags to get verts/edges/etc. arrays again from DM.

This was... horribly wrong, CDDM will often *not* need to allocate
anything to return arrays of mesh items! Just check whether array
pointer is NULL.

Also, remove `DM_get_looptri_array`, that one is useless currently,
`dm->getLoopTriArray` will always return cached array (computing it if
needed).

Cleanup: deduplicate DM's getLoopTriArray() callback.

All three functions were doing exactly the same thing, simpler to only
have one in that case!

Screw Modifier: remove doubles option

Vertices on the axis can be optionally merged,
nice for creating objects which close at the end-points.
