GPU_texture : Add RG8 format.

Eevee: Fix some problem with Glass & Diffuse BSDF with SSR

Diffuse was not outputing the right normal. (this is not a problem with SSR actually)

Glass did not have proper ssr_id and was receiving environment lighting twice.
Also it did not have proper fresnel on lamps.

Fix ubo vec3 alignment issue

This fixes the Principled shader in Eevee, among other nodes.

Basically before we were treating all the vec3 as vec4 as far as memory
goes. We now only do it when required (aka, when the vec3 is not
followed by a float).

We can be even smarter about that and move the floats around to provide
padding for the vec3s. However this is for a separate patch.

That said, there seems to be some strong consensus in corners of the
internet against using vec3 at all [1]. Basically even if we get all the
padding correct, we may still suffer from poor driver implementations in
some consumer graphic cards.

It's not hard to move to vec4, but I think we can avoid doing it as much
as possible. By the time 2.8 is out hopefully most drivers will be
implementing things correctly.

PyAPI: Gawain checks for range

Raise error on vert-buffer data overflow.
Also exception on attempting to fill data thats already on the GPU.

PyAPI: Fix memory leak w/ empty, allocated enums

CMake: Boost no longer needed for Audaspace

Fix building w/o Audaspace

Audaspace: Moving audaspace 1.3 into extern.

Deleting the old internal audaspace.

Major changes from there are:
- The whole library was refactored to use C++11.
- Many stability and performance improvements.
- Major Python API refactor:
- Most requested: Play self generated sounds using numpy arrays.
- For games: Sound list, random sounds and dynamic music.
- Writing sounds to files.
- Sequencing API.
- Opening sound devices, eg. Jack.
- Ability to choose different OpenAL devices in the user settings.

Cleanup: use lowercase prefix for local API's

Also some minor corrections.

PyAPI: Iniital gawain API for Python

Wraps vertex-format, vertex-buffer and batch's (enough for drawing).

Doesn't yet expose index-buffers or shaders.

RNA: don't register manipulator properties by name

Matching behavior for operators.

Fix leak in Python BGE filter & image types

Cycles: Fix for a division by zero that could happen with solid angle triangle light sampling

Fix T52401: "Export Keying Set" operator generated incorrect ID's for shapekeys

To be backported.

Improved triangle sampling for mesh lights

This implements Arvo's "Stratified sampling of spherical triangles". Similar to how we sample rectangular area lights, this is sampling triangles over their solid angle. It does significantly improve sampling close to the triangle, but doesn't do much for more distant triangles. So I added a simple heuristic to switch between the two methods. Unfortunately, I expect this to add render time in any case, even when it does not make any difference whatsoever. It'll take some benchmarking with various scenes and hardware to estimate how severe the impact is and if it is worth the change.
