OSX/cmake: don't try get xcode path from xcode before 4.3, developer dir was not bundled in this case

minor style clanup and use more meaningful name for 3DCONNEXION source code.

Code cleanup: spelling correction

BGE: Adding a Python collision API. The initial patch was provided by agoose77, with some edits by me.

KX_GameObject now has a collisionCallbacks list which is a list of callables that are called when a collision occurs. The callables will be called with an argument that contains a reference to the other object involved in the collision (i.e., not self).

fix weird issue after last commit where grab brush would not work and
also warnings fix and description fix.

minor changes needed for building standalone mathutils.

Sculpting:

* Cleanup for previous commit and reduce some local variable referencing
* Add support for brushes that operate on frontfaces only and do not
show the option for those brushes. Currently only clay strips is in the
list but this may change according to artist feedback. This should take
care of the "sticky" surface problem completely.

Sculpting:

Modify calculation of sculpt plane to only take into account forward
facing vertices. This will solve cases where sculpting on a volume with
the two sides of the mesh inside the brush radius could move the sculpt
plane inside the mesh volume.

To completely fix the issue where the mesh would "stick" the two sides
of the mesh together on the sculpt plane (for instance for clay strip
brushes), user should enable "front face only". Perhaps some brushes,
like clay strips should enforce this and not present the option in the
first place.

Cleanup for last commit

Fix broken compiling with ndof on linux and win

OSX/cmake: move the new xcode-select-handing outside xcode conditional, to fix cmake/make compile

Fix for #36720 and #36721.
This was own error in r60049 which fixed chunk number calculation. This was mixing int and unsigned int values from ExecutionGroup, which leads to huge chunk numbers which are then skipped.

OSX/scons: take xcode-select path into account, to work well with different xcode versions

OSX: Compilefix for ndof symbols get magled when used extern C, now use discrete c files embedded, patch by Jake Kauth

OSX/cmake: allow for compiling with xcode develper previews by determing xcode-select

Fix #36719: UV pass not rendering in second render layer if first render layer
does not have the UV pass enabled as well.

Cleanup and improvements of the compositor debug output.

Debug code for graphviz output moved to a dedicated file COM_Debug.h/cpp.

The DebugInfo class has only static functions, which are called from a number of places to keep track of what is happening in the compositor. If debugging is disabled these are just inline stubs, so we
don't need #ifdefs everywhere and don't get any overhead.

The graphviz output is much more useful now. DebugInfo keeps track of node names in a static string map for meaningful names. It uses a number of colors for various special operation classes.
ExecutionGroups are indicated in graphviz with clusters.

Currently the graphviz .dot files are stored in the BLI_temporary_dir() folder. A separate dot file is generated for each stage of the ExecutionGroup scheduling, this is intended to give some idea of the
compositor progress, but could still be improved.

Related to #36710: add a "use_viewport" option to the render operator, to specify
if the layers and camera of the 3d viewport should be used. Python scripts don't
always want this behavior.

Fix memory leak reading mesh data after change to skip saving temporary
custom data layers.

Match free_normals_split with calc_normals_split names ;)
