===========================
Commiting camera tracking integration gsoc project into trunk.
This commit includes:
- Bundled version of libmv library (with some changes against official repo,
re-sync with libmv repo a bit later)
- New datatype ID called MovieClip which is optimized to work with movie
clips (both of movie files and image sequences) and doing camera/motion
tracking operations.
- New editor called Clip Editor which is currently used for motion/tracking
stuff only, but which can be easily extended to work with masks too.
This editor supports:
* Loading movie files/image sequences
* Build proxies with different size for loaded movie clip, also supports
building undistorted proxies to increase speed of playback in
undistorted mode.
* Manual lens distortion mode calibration using grid and grease pencil
* Supervised 2D tracking using two different algorithms KLT and SAD.
* Basic algorithm for feature detection
* Camera motion solving. scene orientation
- New constraints to "link" scene objects with solved motions from clip:
* Follow Track (make object follow 2D motion of track with given name
or parent object to reconstructed 3D position of track)
* Camera Solver to make camera moving in the same way as reconstructed camera
This commit NOT includes changes from tomato branch:
- New nodes (they'll be commited as separated patch)
- Automatic image offset guessing for image input node and image editor
(need to do more tests and gather more feedback)
- Code cleanup in libmv-capi. It's not so critical cleanup, just increasing
readability and understanadability of code. Better to make this chaneg when
Keir will finish his current patch.

Further development of small features would be done in trunk, bigger/experimental
features would first be implemented in tomato branch.
- remove unneeded type check from convert grease pencil operator.
- correct some error prints & use __func__.
- make copy_libblock take an ID* argument rather than void*.
so path manipulation functions dont run multiple times on the same path in the case of sequence strips where the one directory is used as the base for many images.
Added a visitor function to simplify processing of file paths that are attached to IDs. This is used for images, and could be used for other ID types in future.
Code reviewed by ideasman_42.
Made a major amount of conflict resolution for code adaptation to
the animation system updates introduced in the Pepper branch recently
merged to the trunk.

Speaker objects fully functional!
Minor changes:
* Fixed three memory bugs found via valgrind.
* Fixed bug with jack transport crashing after file loading.
* Sound NLA Strips now start at CFRA instead of 0.
* Use the same method as from unlinking actions to do this.
* Split off the make single-user code used for the ID-browser into a
function in blenkernel which can be used elsewhere. Getting materials
to also work using this method proved to be a bit too tricky (due to
the whole messy ob vs obdata situation), so I haven't done that.
This uses pythons GC so its no overhead during runtime but makes removing ID's slower.
Commented definition 'USE_PYRNA_INVALIDATE_GC' for now, so no functional change.
- use NULL rather then 0 where possible (makes code & function calls more readable IMHO).
- set static variables and functions (exposed some unused vars/funcs).
- use func(void) rather then func() for definitions.
