===========================
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.
* Adds two new python handlers: scene_update_pre() and scene_update_post()
These run before and after Blender does a scene update on making modifications
to the scene.
* Datablocks now have an is_updated property. This will be set to true in the
above callbacks if the datablock was tagged to be updated. This works for the
most common datablocks used for rendering: object, material, world, lamsp,
texture, mesh, curve.
* Datablock collections also have an is_updated property. If this is set, it
means one datablock of this type was added, removed or modified. It's also
useful as a quick check to avoid looping over all datablocks.
* RenderEngine.view_update() can also check these properties, for interactive
viewport rendering.

- The object ID was being passed to the data_delete_material_index_id() from object_remove_material_slot(), rather then the object data. (so the material slot fix wouldnt run in that case).
- add support for fixing text object materials too.
create a new parameter for materials.pop() to not remove material slot.
this way the mat_nr is still the old one.
for the default behaviour we now have material remapping (i.e. data_delete_material_index_id(id, index)).
This new function is brought from the material_slot remove function.
The problem was flag-enums were being treated as regular enums, a default value of 0 was using the first enum item, whereas with flag enums we want to be able to use 0 as a default value to specify all flags are off.
move Object.update(...) to ID.update(). since depsgraph update function can now be called on ID types.
also changed how update flags work.
obj.update(scene, 1, 1, 1)
... is now
obj.update({'OBJECT', 'DATA', 'TIME'})
Don't pass scene anymore. This was used for recalculating text but I think this is better dont in a different function.
- open operator was incorrectly checking if the font path was set.
- rna ID editable check was also incorrect, checking the ID name rather then the filename.
- use define FO_BUILTIN_NAME rather then "<builtin>".
- set_frame() --> frame_set()
- set_context_pointer() --> context_pointer_set()
material adding works for curves and metaballs, new function to remove materials.
materials.link() didnt well fit how this is used elsewhere
- order matters
- it can be linked more than once.
- remove(material), isnt that useful since you need to manage indicies.
... use list style functions instead. materials.append(mat) / materials.pop(index)
An example of how this is useful - an importer mixin could define the filepath properties and a generic invoke function which can run the subclasses exec for each selected file.
- Panels and Menus now skip the property check when registering.
- renamed _idproperties_ to _idprops_ in function names, function names were getting very long.
utility functions to find the groups and scenes this object is used in.
button to set the group location from the cursor (UI is horrible but not any nice place to add?)
smarp project would fail if there were linked meshes in the scene, made ID.tag ignore the library, so you can tag linked data since its only for tools to use.
normalize the vertex normal before setting and use inline vector functions.
for panels it would fail silently but for menu's it meant further references would give errors.
increase the registered class name from 32 to 64 and raise an error if the limit reached.
