* Split render/ into scene/ and session/. The scene/ folder now contains the
scene and its nodes. The session/ folder contains the render session and
associated data structures like drivers and render buffers.
* Move top level kernel headers into new folders kernel/camera/, kernel/film/,
kernel/light/, kernel/sample/, kernel/util/
* Move integrator related kernel headers into kernel/integrator/
* Move OSL shaders from kernel/shaders/ to kernel/osl/shaders/
For patches and branches, git merge and rebase should be able to detect the
renames and move over code to the right file.

Currently in fractal_noise functions, each subsequent octave doubles the
frequency and reduces the amplitude by half. This patch introduces Roughness
input to Noise and Wave nodes. This multiplier determines how quickly the
amplitudes of the subsequent octaves decrease.
Value of 0.5 will be the default, generating identical noise we had before.
Values above 0.5 will increase influence of each octave resulting in more
"rough" noise, most interesting pattern changes happen there. Values below
0.5 will result in more "smooth" noise.

There were to copies of stdosl.h one from stock OSL
and one in the cycles tree augmented with cycles
specific closures.
moved the cycles ones to stdcycles.h and copied
the stock stdosl.h and accompanying headers from
the OSL shader folder.
for further details see D6812.

Previously Noise and Wave texture nodes would use noise functions within a [0,1]
range for distortion effects. We either add or subtract noise from coordinates,
never do both at same time. This led to the texture drastically shifting on the
diagonal axis of a plane / cube. This behavior makes the Distortion input hard
to control or animate. Capabilities of driving it with other texture are also
limited, diagonal shifting is very apparent.
This was fixed by offsetting the noise function to a signed range and making it
zero-centered. This way noise is uniformly added and subtracted from coordinates.
Texture pattern sticks to main coordinates which makes it way easier to control.
This change is not strictly backwards compatible, there is versioning to ensure
the scale of the distortion remains similar, but the particular pattern can be
a little different.

This patch extends perlin noise to operate in 1D, 2D, 3D, and 4D
space. The noise code has also been refactored to be more readable.
The Color output and distortion patterns changed, so this patch
breaks backward compatibility. This is due to the fact that we
now use random offsets as noise seeds, as opposed to swizzling
and constants offsets.

Apply clang format as proposed in T53211.

Same as last commit, code is unused and this one actually would have required some fixes,
as these variants output values outside the 0-1 value range, which doesn't fit Cycles shader design.

This was already mixed a bit, but the dot belongs there.

* Simplify default color values, where each component was the same.
* Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.

* Renamed standard attributes to use geom:, particle:, object: prefixes
* Update stdosl.h to properly reflect the closures we support
* Fix the wrong stdosl.h being used for building shaders
