Fix/Cleanup mesh remap dest transformation in tree/source space.

In org work, bvhtree helpers were modifying passed co/no in place according to given transform.

However, during review pass we decided this was bad, and made them modify copies. But this broke
some cases where we'd do extra tests after bvhtree query, expecting tmp_co to be in tree (aka source) space!

Further more, since in quite a few cases we were already doing that transform outside of bvhtree helpers,
decided to remove this alltogether from the helpers - makes things more clear and easy to follow,
avoids needless copy of vector, and ensures we are always using tmp_co in its transformed version!

Correct default enum values

Cycles: Add debug print about CLEW initialization status

Cycles: Add an option to force disable all OpenCL devices

This way it's possible to disable OpenCL devices for AMD devices
which are considered whitelisted.

BGE: Fix wrong current logic manager in collision callback.

Remove redundant lists, link instead

Remove unnecessary constant info

Noting every constant as an int isnt helping,
this is only meant to be passed to only.

Fix for recent error, ngons now flipped correctly

Using proper subtype in game object velocity clamping properties.

The game.velocity_{min,max} and game.angular_velocity_{min,max} object
RNA properties did not use a subtype, and thus velocity was always
displayed as radians or blender units instead of the configured units.

BGE: bge.texture API documentation enhancement

This patch attempts to improve and review the documentation of bge.texture, as requested in the [[ http://wiki.blender.org/index.php/Dev:2.5/Source/Development/Todo/GameEngine#Video_Texture | TODO list ]].

More specifically, it

- fixes the rst syntax, including titles of the examples bge.texture.py and bge.texture.1.py;

- adds, standardizes and reviews description of the API elements, particularly signatures, types, etc.

- adds SOURCE_* constants to the doc

- splits the doc into thematical parts (Video, Image, Texture, and Filter Classes, Functions, Constants).

Notes:

- The parameter "mode" of ImageBuff.plot has to be described better. Actually, the whole set of IMB_BLEND_* constants (from IMB_imbuf.h) should be exposed to Python. I'll do that in a future diff, and complete the doc at the same moment (adding those IMB_BLEND_* constants to the Constants part of this doc).

- The option of using webcams in VideoFFmpeg is still particularly not well documented. I am planning to make a proposal about fixing T18634 (and its corresponding TODO in the list) by integrating OpenCV in the BGE (and Blender?). The idea would then probably be to add a new class, f.ex. ImageWebcam, making this functionnality more specialized. So for now I don't think it is worth to document that part much.

This patch fixes T44284 too.

The camera-aiming code was using a near-zero-length cross product, which
caused oscillations. Thresholding on the cross product length seems to
fix this.
