0f339a748e Cycles: Quick (real) fix for broken textures on OpenCL
Previous fix did not work for mixed textures. This one will over-allocate
information array, but it's better than not being able to render at all.

Some more cleanup and improvement is coming.

1ec59c8e06 Revert "Cycles: Fix image textures were completely broken since recent unlimited textures commit"
This reverts commit 8f4166ee495531fa38b676b0a5ef4c482e89f9a5.

The fix was not correct for cases when we've got float textures.

ec25060a05 Unlimited number of textures for Cycles
This patch allows for an unlimited number of textures in Cycles where the hardware allows. It replaces a number static arrays with dynamic arrays and changes the way the flat_slot indices are calculated. Eventually, I'd like to get to a point where there are only flat slots left and textures off all kinds are stored in a single array.

Note that the arrays in DeviceScene are changed from containing device_vector<T> objects to device_vector<T>* pointers. Ideally, I'd like to store objects, but dynamic resizing of a std:vector in pre-C++11 calls the copy constructor, which for a good reason is not implemented for device_vector. Once we require C++11 for Cycles builds, we can implement a move constructor for device_vector and store objects again.

The limits for CUDA Fermi hardware still apply.

7c1263c1ee Cycles: Allow samples to finish in split kernel to avoid artifacts when canceling
Previously canceling a render done by the split kernel could cause artifacts
such as very bright or dark tiles. This was caused by unfinished samples
being included in the output buffer. To avoid this we now wait till all the
currently rendering samples have finished, up to a limit of twice the
expected time for them to finish (currently this is no more than 20 seconds,
but usually its much less). If samples still haven't finished by then we
stop anyways in case there's an endless loop occurring.

e91dc3a97c Cycles: use safe compiler flags for OpenCL.
Using -cl-fast-relaxed-math assumes no NaN/Inf values in any expression.
This causes problems on overflow, division by zero, square root of negative number.
Comparisons with NaN or infinite value are affected as well.

This patch causes <2% slowdown on benchmark scenes.

51ec9441b7 Cycles: Split vectorized types into separate files
The final goal to reach is to make vectorized types much easier to maintain
and the previous design had following issues:

- Having all types and methods implementation made the source file rather
  bloated and unfun to navigate in.

- It was not possible to quickly glance available API for the type you are
  interested in.

- Adding more vectorization types will bloat the file even more, making
  things even more tricky to follow.

It is disabled by default, so should not affect existing configurations.

Main benefits of this goes as:

- Linux distros can use that to avoid libraries duplication and link
  blender package against gflags package from the system.

- It it easier to test whether Blender works with updated version of
  Gflags prior to re-bundling the library.

Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Fri Sep 16 08:47:56 2016 +0200

    Fixed a bug in the Disney BSDF that caused specular reflections to be too
    bright and diffuse is now reacting to the roughness again

    - A normalization for the fresnel was missing which caused the specular
      reflections to become too bright for the single-scatter GGX
    - The roughness value for the diffuse BSSRDF part has always been
      overwritten and thus always 0
    - Also the performance for refractive materials with roughness=0.0 has
      been improved

    Added selection field to the Disney BSDF node for switching between
    "Multiscatter GGX" and "GGX"

    In the "GGX" mode there is an additional parameter for changing the
    refraction roughness for materials with smooth surfaces and rough interns
    (e.g. honey). With the "Multiscatter GGX" this effect can't be produced at
    the moment and so here will be no separation of the two roughness values.

Date:   Tue Aug 16 15:17:12 2016 +0200

    Implemented the fresnel in the multi-scatter GGX for the Disney BSDF

    - The specular/metallic part uses the multi-scatter GGX
    - The fresnel of the metallic part is controlled by the specular value
    - The color of the reflection part when using transparency can be
      controlled by the specularTint value

    Attempt to fix Disney SSS

commit dbad91ca6d46f5a4a6f2ba7ed4c811ffa723942f
Author: Pascal Schoen <pascal_schoen@gmx.net>
Date:   Wed Jul 20 11:13:00 2016 +0200

    Added a roughness parameter for refractions (for scattering of the rays
    within an object)

    With this, one can create a translucent material with a smooth surface and
    with a milky look.

    The final refraction roughness has to be calculated using the surface
    roughness and the refraction roughness because those two are correlated
    for refractions. If a ray hits a rough surface of a translucent material,
    it is scattered while entering the surface. Then it is scattered further
    within the object. The calculation I'm using is the following:

    RefrRoughnessFinal = 1.0 - (1.0 - Roughness) * (1.0 - RefrRoughness)

dd356ec08d Cycles: Remove meaningless volume shaders
This is possible to use surface-only nodes and connect them to volume output.
If there was something connected to surface output those extra connections
will not change anything visually but will force volume features to be included
into feature-adaptive kernels.

In fact, this exact reason seems to be causing slowdown of Barcelone file
comparing AMD OpenCL to NVidia CUDA.

Currently only supported by the final F12 renders because of the current design
of what gets optimized out when and how feature-adaptive kernel accesses
list of required features.
