Camera tracking: switch to own repo of libmv where most of patches are applied

and which includes latest changes from Keir's branch.

Hopefully it'll make backporting of changes back to main libmv repo easier.

+Date:   Fri Feb 17 19:25:45 2012 +0600
+
+    Add support for detecting tracking failure in the ESM tracker component of
+    libmv. Since both KLT and Hybrid rely on ESM underneath, KLT and Hybrid now
+    have a minimum correlation setting to match. With this fix, track failures
+    should get detected quicker, with the issue that sometimes the tracker will
+    give up too easily. That is fixable by reducing the required correlation (in
+    the track properties).
+
+commit ea0fed736ecdcc8c020227aeef8ef4cd3be5e63d
+Author: Keir Mierle <mierle@gmail.com>
+Date:   Fri Feb 17 19:23:50 2012 +0600
+
+    Add a new hybrid region tracker for motion tracking to libmv, and
+    add it as an option (under "Hybrid") in the tracking settings. The
+    region tracker is a combination of brute force tracking for coarse
+    alignment, then refinement with the ESM/KLT algorithm already in
+    libmv that gives excellent subpixel precision (typically 1/50'th
+    of a pixel)
+    
+    This also adds a new "brute force" region tracker which does a
+    brute force search through every pixel position in the destination
+    for the pattern in the first frame. It leverages SSE if available,
+    similar to the SAD tracker, to do this quickly. Currently it does
+    some unnecessary conversions to/from floating point that will get
+    fixed later.
+    
+    The hybrid tracker glues the two trackers (brute & ESM) together
+    to get an overall better tracker. The algorithm is simple:
+    
+    1. Track from frame 1 to frame 2 with the brute force tracker.
+        This tries every possible pixel position for the pattern from
+        frame 1 in frame 2. The position with the smallest
+        sum-of-absolute-differences is chosen. By definition, this
+        position is only accurate up to 1 pixel or so.
+    2. Using the result from 1, initialize a track with ESM. This does
+        a least-squares fit with subpixel precision.
+    3. If the ESM shift was more than 2 pixels, report failure.
+    4. If the ESM track shifted less than 2 pixels, then the track is
+        good and we're done. The rationale here is that if the
+        refinement stage shifts more than 1 pixel, then the brute force
+        result likely found some random position that's not a good fit.

+commit a07fff8431621c01d81ae52595d8dd91a295a776
+Author: Keir Mierle <mierle@gmail.com>

+
+    Assorted camera tracker improvements
+    
+    - Add support for refining the camera's intrinsic parameters
+      during a solve. Currently, refining supports only the following
+      combinations of intrinsic parameters:
+    
+        f
+        f, cx, cy
+        f, cx, cy, k1, k2
+        f, k1
+        f, k1, k2
+    
+      This is not the same as autocalibration, since the user must
+      still make a reasonable initial guess about the focal length and
+      other parameters, whereas true autocalibration would eliminate
+      the need for the user specify intrinsic parameters at all.
+    
+      However, the solver works well with only rough guesses for the
+      focal length, so perhaps full autocalibation is not that
+      important.
+    
+      Adding support for the last two combinations, (f, k1) and (f,
+      k1, k2) required changes to the library libmv depends on for
+      bundle adjustment, SSBA. These changes should get ported
+      upstream not just to libmv but to SSBA as well.
+    
+    - Improved the region of convergence for bundle adjustment by
+      increasing the number of Levenberg-Marquardt iterations from 50
+      to 500. This way, the solver is able to crawl out of the bad
+      local minima it gets stuck in when changing from, for example,
+      bundling k1 and k2 to just k1 and resetting k2 to 0.
+    
+    - Add several new region tracker implementations. A region tracker
+      is a libmv concept, which refers to tracking a template image
+      pattern through frames. The impact to end users is that tracking
+      should "just work better". I am reserving a more detailed
+      writeup, and maybe a paper, for later.
+    
+    - Other libmv tweaks, such as detecting that a tracker is headed
+      outside of the image bounds.
+    
+    This includes several changes made directly to the libmv extern
+    code rather expecting to get those changes through normal libmv
+    channels, because I, the libmv BDFL, decided it was faster to work
+    on libmv directly in Blender, then later reverse-port the libmv
+    changes from Blender back into libmv trunk. The interesting part
+    is that I added a full Levenberg-Marquardt loop to the region
+    tracking code, which should lead to a more stable solutions. I
+    also added a hacky implementation of "Efficient Second-Order
+    Minimization" for tracking, which works nicely. A more detailed
+    quantitative evaluation will follow.

+Author: Keir Mierle <mierle@gmail.com>
+Date:   Fri Feb 17 19:00:28 2012 +0600
+
+    Improve the KLT tracking behaviour and UI
+    
+    - Remove the overly-conservative use of libmv's re-track tracker. The re-track
+      tracker would take a normal tracker such as TRKLT or KLT or pyramid KLT, and
+      track from frame 1 to 2, then back from the position found in 2 back to 1.
+      Then, when the reverse-track doesn't match the original track with high
+      precision, the track is considered "failed". This is a good approach for
+      fully automatic reconstruction, but is too conservative for supervised
+      tracking.
+    
+      The retrack-tracker will return when fully automatic tracking is added.
+    
+    - Always solve for (dx, dy) in the TRKLT loop even if the linear system is
+      ill-conditioned. The client (Blender in this case) can still use the solved
+      position, even though it is less reliable.
+
+commit 7d8a8762f2bc2e36f95b0b6f4fb4ca996f9f0db7
+Author: Sergey Sharybin <sergey.vfx@gmail.com>
+Date:   Fri Feb 17 18:46:24 2012 +0600
+
+    Changes in camera intrinsics distortion/undistortion:
+    
+    - Distortion/undistortion of scaled images wasn't happening right,
+      because camera intrinsics are calibrated on an original frame which
+      has got some particular resolution and trying to apply this model on
+      an image with another resolution gives totally wrong result.
+      This is needed to be able to do post-prccessing of render, running
+      distortion on a scene which might be rendered with higher resolution
+      than footage itself and then be scaled down.
+    - Fixed incorrect calculation/applying of precomputed grid when
+      distortion is high high enough and produces pixel offset higher
+      than 127 pixels. This might be still not very distorted image,
+      but if it's a 4K footage "normal" camera will easily give such
+      a distortion.
+    - Added support of overscan distortion/undistortion.
