Cycles: Fix missing feature reported by the Volume node

Cycles: Fix missing volumes support for feature-adaptive viewport render

Fix for all OpenGL lights affecting Cycles viewport, regardless of their Enabled state

Was a regression since e1b8a5d.

Probably not very optimal fix, but better than a regression anyway.

Cleanup: glsl indentation, line length

Code cleanup, stick closer to a blender code style in GLSL shader

Support Vertex Color in GLSL viewport for Cycles

The title says it all actually.

Added special custom data type, because we don't know in advance
whether we're referencing UV or Color layer. Also made it so vertex
attributes are normalized.

TODO: Border render in viewport ignores the normalization of the
attribute array for some reason, will be looked into still.

Cleanup: Use short condition style.

Support Musgrave texture for Cycles GLSL viewport

Only for non-OSX viewport!

Fix T48497: Stupid typo in recent own BLI_task forloop work that broke non-parallelized case.

Cleanup: remove Cycles layer bits checking in the kernel.

At some point the idea was that we could have an optimization where we could
render multiple render layers without re-exporting the scene, by just updating
the layer bits. We are not doing this now and in practice with the available
render layer control like exclude layers it's not always possible anyway.

This makes it easier to support an arbitrary number of layers in the future
(hopefully this summer), and frees up some useful bits in the kernel.

Fix missing Ignore option for GLSL bump

Use previous shading mode for border render in viewport

This way we can have border rendered part in the viewport and have
everything else material/texture shaded.
