Code Refactor: Creating utility function for updating boundary hulls

Merge remote-tracking branch 'origin/master' into soc-2016-uv_tools

BMesh: remove redundant walker member & assignment

Cycles: Deduplicate AO calculation

No functional changes.

UI: Don't show empty panel right-click menu

Cycles: Fix OpenCL compilation with the new brick texture

Cycles: Style Fix: Light sampling threshold description

Viewport smoke: add support to render the volume using a color ramp.

This is yet another debug option that allows to render an arbitrary
simulation field by using a color ramp to inspect its voxel values.
Note that when using this, fire rendering is turned off.

Cycles: Initialize the RNG state from the kernel instead of the host

This allows to save a memory copy, which will be particularly useful for network rendering.

Cycles: Add optional probabilistic termination of light samples based on their expected contribution

In scenes with many lights, some of them might have a very small contribution to some pixels, but the shadow rays are traced anyways.
To avoid that, this patch adds probabilistic termination to light samples - if the contribution before checking for shadowing is below a user-defined threshold, the sample will be discarded with probability (1 - (contribution / threshold)) and otherwise kept, but weighted more to remain unbiased.
This is the same approach that's also used in path termination based on length.

Note that the rendering remains unbiased with this option, it just adds a bit of noise - but if the setting is used moderately, the speedup gained easily outweighs the additional noise.

Fix compile errors for when WITH_ALEMBIC is OFF.

Cycles: Add smoothing option to the Brick Texture

This option allows to create a smoother transition between Bricks and Mortar - 0 applies no smoothing, and 1 smooths across the whole mortar width.
Mainly useful for displacement textures.

The new default value for the smoothing option is 0.1 to give some smoothing that helps with antialiasing, but existing nodes are loaded with smoothing 0 to preserve compatibility.

reverting to old IO functions. changes from D2317 produce posixpath, mantaflow save() and load() require string though

Mantaflow: Fix typo in smoke_export_low script.

Fix T49846: OpenCL rendering compilation failure

Cycles: Implement texture coordinates for Point, Spot and Area Lamps

When using the Normal output of the Texture Coordinate node on Point and Spot lamps, the coordinates now depend on the rotation of the lamp.
On Area lamps, the Parametric output of the Geometry node now returns UV coordinates on the area lamp.

Credit for the Area lamp part goes to Stefan Werner (from D1995).

Fixed cmake option for htc vive in OpenHMD

Fix T49878: Alembic crash with long object name

Crash comes from writing to char array (ID::name) out its bound and thus
overriding memory in the ID struct.

- Added initial HTC Vive support, still uses complimentary sensor fusion, could drift a bit

- Updated Oculus CV1 support
