Merging r38419 through r38432 from trunk into soc-2011-tomato

print an error message if Python.h can't be found for cmake and scons since its such a common problem.

Bugfix [#27157] keyframing a constrained bone does not work as before

Visual Keyframing was broken by r.34685, which used another method
which, at the time, appeared to work perfectly fine. Apparently not.

Also, extend/fixed visual keying to work for axis-angle rotations too.
Needs some testing, but should probably work

BGE Animations: Updating the python docs.

BGE Animations: Some updates to the Python api:
* Adding methods KX_GameObject.stopAction() and KX_GameObject.isPlayingAction().
* Made all layer arguments optional. This means I had to change setActionFrame(layer, frame) to setActionFrame(frame, layer=0). This seems a little backwards to me, but I guess that's what you get with optional arguments. Also, this will break existing scripts.
* Made sure to check user supplied layer values on all action methods. Previously this was only done for playAction().
* Fixed a few newline issues.

fix for crash with edit armature buttons when no bones were selected (uninitialized pointer)

Camera tracking integration
===========================

- Bundle re-newed libmv library.
- Update API in libmv-capi to match new library.
- Initial implementaition of feature detection.
- Fixed bug with incorrect user sync when tracking
for first frame.

Merging r38390 through r38418 from trunk into soc-2011-tomato

Removed a remnant to an unsuccessful attempt to get clipping functional so I can merge again.

Camera tracking integration
===========================

Fix for camera solver on windows.

There were two problems:
- Static align in Eigen should be also disabled for libmv.
- SSBA doesn't work correct for windows when optimization is
turned on.

There's no other way rather than disable optimization for
the whole extern/libmv. This leads to 3-4x slowdown, but it's
really the only thing we could do now.

Keir is going to drop SSBA out and replace it with Bundler,
so it shouldn't be a major problem.

Fix for [#26712] Particle group instance 'Use Count' value gets reset on file-load.
* New object pointers can't be loaded properly for library linked groups, so the weight groups now store an index to the group objects at save time. This index is used at load time to set the objects without relying on the old pointers.
* If the library linked group is modified the indices can be wrong, but this can't really be avoided easily as there's no way to relate objects in a linked group between loads.

fix for linking on mingw/scons with recent changes to mathutils

Bugfix: Retargeting now works when user rig bones are not connected to their parents.

move mathutils into its own lib.

Fix for [#27307] Blender crashes when loading a new scene while baking fluid dynamics
* Fluid bakes didn't respect the job stop flag.
* Also made msvc happy with some casts.

removed unused ndof code

more consistent and modal-friendly ndof events, fly mode v1

Added Lasso select and Box select to weight paint.
Clipping still doesn't work properly there.

merge from trunk 38379

Camera trackign integration
===========================

- Fixed compilation error with OpenCOLLADA
- Added sample preset for tracking camera.
- Fixed bug with wrong order of preset properties loading/saving.
