Fix T43776: Rigging : Clear User transform is not working when mesh is in weight paint mode.

Use same trick as for regular 'clear transform' operators to get a valid armature
in weight paint mode (where active object is weight-painted one).

Fix T43740: 'Back to Previous' failed on reload

Would restore with the file-selector where the 'info' header should be.

Screen: remove redundant NULL check in ED_area_prevspace

Partial fix for T43740

ED_area_data_swap would put the screen in an invalid state and crash.
(SpaceLink.spacetype didn't match ScrArea.type)

However behavior is still odd in the instance of the report.

Fix T43769: Envmap Texture copy looses image

CustomData: const correctness

BLI_utildefines: correct comment

Edge/Vert Slide: avoid redundant loop angle calls

No need to calculate loop angle for each layer

Error in last commit

Accidentally left in malloc/free

Fix error in recent vert/edge-slide commits

`CustomData_bmesh_interp_n` was expecting the 'dest' arg not to have its offset applied.

This was a bit confusing since the source args have it applied,
and in some cases we only have the destination with the offset.

CustomData: replace calloc -> malloc

stack array is uninitialized, relying on calloc here would just hide bugs.

CustomData: const correctness for interp()

BLI_utildefines: add pointer offset macro

Handy since it keeps the type of the original.

Subsurf: missing NULL checks on free

Fix T43768: Pointcache end frame ignores preview range

Fix for T43768

This way it works consistent with cloth, softbodys, etc.

Differential Revision: https://developer.blender.org/D1134

Cycles: Make it survive if preview_cycles.blend uses persistent data

Currently should be no functional changes, but nice thing to have fixed
for some further experiments.

Fix T43748: MouseLook actuator raises an Assert error

An assertion seems to be inverted by mistake, as MT_assert(!m_mouse); is followed
by using m_mouse->XXXX.

GPencil: Another fix for the "big square dots" problem

Strokes containing only a single point are now drawn so that they respect the
pressure values too. Previously, they were getting drawn at a fixed size based
on the thickness of strokes. Thanks to @kekeljevic for posting a screenshot which
made the problem here easy to identify!

(On a side note: Perhaps it's a combination of the drivers I'm using, or the
multisampling goodness at work, but after applying this change, the dots are
now appearing as round circles as originally intended, and can also be scaled
up quite a bit too. And that's for 3D points which couldn't be affected like
this earlier! I'm not sure what's going on here, but whatever it is, I like it ;)

Code cleanup: Use bools instead of int

Cycles: Add note about autodiff in OSL wireframe shader
