===========================
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.
functions based on editor types
This could be split up further in future if there's such a need, but
this should already be sufficient. Most notably required since the NLA
recalc stuff was taking quite a few lines within that block
disabled, the strips are drawn so that they take up less vertical
space.
Originally, the primary reason why these were taller than those in the
other animation editors was really so that these control curves could
be visualised adequately. So, when these aren't shown, we can afford
to collapse the strips vertically.
This should make it possible to fit more strips on screen to retime
them. in some staggered fashion.
* This (big) commit is aimed at cleaning up the filtering flags used
by the animation channel filtering code. The list of filtering flags
has been growing a bit "organically" since it's humble origins for use
in the Action Editor some 3 years (IIRC) ago now during a weekend
hackathon. Obviously, some things have ended up tacked on, while
others have been the product of other flag options. Nevertheless, it
was time for a bit of a spring clean!
* Most notably, one area where the system outgrown its original design
for the Action Editor was in terms of the "visibility" filtering flag
it was using. While in the Action Editor the concept of what channels
to include was strictly dictated by whether the channel hierarchy
showed it, in the Graph Editor this is not always the case. In other
words, there was a difference between the data the channels
represented being visible and the channels for that data being visible
in the hierarchy.
Long story short: this lead to bug report [#27076] (and many like it),
where if you selected an F-Curve, then collapsed the Group it was in,
then even after selecting another F-Curve in another Group, the
original F-Curve's properties would still be shown in the Properties
Region. The good news is that this commit fixes this issue right away!
* More good news will follow, as I start checking on the flag usage of
other tools, but I'm committing this first so that we have a stable
reference (of code similar to the old buggy stuff) on which we can
fall back to later to find bugs (should they pop up).
Anyways, back to the trenches!
* Removed list-expanders for Materials, Textures, and Particles. So
instead of:
Object
Materials
Material 1
... material 1 anim data ...
we now have
Object
Material 1
... material 1 anim data ...
This makes it faster+easier to get to these items. If you don't want
to see all of these, you can still use the data-block filters from the
header to hide these.
* Internal cleanup - removed "owner" and "ownertype" settings from
bAnimListElem. The purpose of these was muddled, and more of a hassle
to maintain than doing anything useful - it was only really used for
the stuff above.
* Removed need for "sa->spacedata.first" casts all over the show for
animation editor tools which needed access to editor data. This can
now be retrieved directly.
