More build fixes for r58428.

fix own bad regression/bug, removing vertex colors crashes [#36227]

SCons fix for r58428.

Removing source files from source/gameengine/GamePlayer/common/SConscript that were removed in an earlier commit. This should allow SCons to build the game engine again.

Cycles / CPU Rendering:
* "Auto Detect" now again uses the umber of cores, instead number of cores + 1.

This was added before we had Tile rendering and benchmarks on several systems showed that there is no gain with this now. There might be some slight difference (0.5% or so) slower/faster depending on the scene, but this is negligible.

edit to r58425, BLI_math is available here, better not copy,paste from linearrgb_to_srgb.
also remove redundant check in AUD_FFMPEGReader::seek.

* Compile fix for overloaded pow() function.

revert r58419. caller should do NULL check here.

Cycles / Sampling Presets:
* Add Presets for Sampling. This comes with a simple Preview and Final preset, but as this is varying a lot depending on the scene, they should just be a starting point. The user can add own presets here.

* Some UI layout changes to match the settings a bit better.

BGE: Partial fix for [#36151] "Distance model not carrying over to standalone" reported by Florian Schneider (drjaska).

The Blenderplayer wasn't initializing 3D audio settings from the scene settings like the embedded player was.

BGE fix [#35195] Shadow Only lamps only work with Specular enabled

The way we do shadow only doesn't work well with colored shadows, though it does work if you apply enough light to the shadow.

Code cleanup / Cycles:
* Use USHRT_MAX rather than manual value, suggested by Campbell.

BGE fix [#35563] Object colour setting for objects and fonts not using colour management like materials

Cycles / Sampling UI:
* Add a "Squared Samples" option to the UI, to use squared values for ease of use. This can make it easier from an artist point of view, to weak settings.

With this enabled, all Sample values will be squared. So 10 Samples become 100 Samples.
For the Non-Progressive integrator: 4 AA Samples * 5 Diffuse Samples would become 16 AA Samples * 25 Diffuse = 400 in total.

Patch by Matt Heimlich, with some minor edits by myself. Thanks!

Merging from ge_dev to trunk r58091-58422.
