Cycles: optimize one normalization out from the previous commit

Cycles: implement pointiness geometry attribute

This attribute means how "pointy" the geometry surface is, which allows to do
effects like dirt maps and wear-off effects on render geometry. This means the
attribute is calculated for the final mesh which means no baking (which implies
UV unwrap) is needed. Apart from this the behavior is quite close to how vertex
dirty colors works.

The new attribute is available as an output socket of Geometry node.

There's no penalty for the render time, only some delay on scene preparation
(the delay is linear of the mesh complexity).

Tests: Disable failing import/export tests for until they're fixed

Cycles: Bring back distance check in re-intersection

From more investigation of the numeric failures in the kernel it appears
the check was rather correct. But in theory it;s also needed for the motion
triangles.

Cycles: Correction to glossy shaders not handling total internal reflection

The issue was caused by lack of check for whether fresnel term is actually
giving total internal reflection in refraction BSDFs. This lead to usage of
arbitrary vector of (0, 0, 0) as reflection, giving numeric issues in other
areas of the kernel.

This gives some visual changes of sharp reflection but it seems to be rather
proper now. Which also corresponds with rough glossy reflection with sharpness
set to 0.001 (previously it was totally different from sharpness of 0.0, which
is just weird).

Fix T43596: Refraction BSDF crashes blender on pre-sse4 CPU

This is the same issue T43475: SSE4 code is more robust to non-finite values
in the ray origin/direction. So for now added a check before doing BVH traversal
for pre-SSE4 CPUs.

For sure actual root of the issue is a bit different and much more tricky to
solve, especially without disturbing render results too much. Still looking
into this.

In any case, it's kinda fine to have such a check, we might later make it to be
a kernel_assert() instead of just a return.

Fix grease-pencil crash without clip/track data

UI: scale timeline cache-height by DPI/pixelsize

D602 by @blakenator with edits

correct last commit

Fix: Grease Pencil datablocks can be copied using the ID.copy() API method now

Fix T43611: Collision shape of rigid bodies changes inadvertently

The issue was caused by the fix for T34108, which modified DNA in order to
get a fallback box collision shape. Not sue why it's needed, we can just get
box shape directly, without modifying user's settings.

Nodes: Various UI cleanups for Image and Environment Texture Nodes

Mainly consistency changes and smaller fixes.

* Environment Texture Nodes:
** show image info
** split layout for menus (showing menu title on the left)
** hierarchical button order

* Image Nodes:
** disable Alpha Mode menu if Use Alpha is disabled
** Don't show "+" icon/button if an image is already loaded
** Consistent alignment of menu buttons (see Input Color Space menu)

Requested and approved by @venomgfx

Nodes: (Un)pack, filepath, refresh buttons for Environment Texture nodes

The same buttons are already used for other image textures and since the
environment tex node does only allow images as well, it makes sense to
have this here too.

CMake cleanup: Move OSL detection code into FindOpenShadingLanguage.cmake

Should be no functional changes.

Fix file size not drawn using Link/Append

For linking/appending, .blends get the type S_IFDIR added which prevents
the size from being drawn. BLI_is_dir gets the type from the OS so it's
better suited for this case.

BGE - Vehicle Controller - add background and API checks for arguments of function calls

Fixes T41570 crash
For readability, attachDir was renamed to downDir and the Python API docs renamed accordingly

Recreating bge python modules instead of using existing

All of the initXPythonBinding functions are changed to always creating the module instead of importing if previously existing.
I can instead only remove the module return when the import is ok, so that it always inits. But then, I don't see the point in importing.

I make sure that these functions are called only once per run, inside initBGE.
This was not the case with GameTypes. I moved initPyTypes inside of initGameTypesPythonBinding due to that.

I reorganized initGamePlayerPythonScripting and initGamePythonScripting so that they run things in the same order.
initGamePlayerPythonScripting imports mathutils and aud, the other only aud. Shouldn't it be the same for both?

Fix T43424: undo changes the active scene

Using different scenes with 2+ windows broke entirely using undo.
Now keep track of the current windows scene in each undo-file,
and ensure the undo-scene is on a visible window when undo is executed,
switching the scene only when its not in a visible window.
