Removed the extra ntree->update flag check in lib_verify_nodetree in readfile.c. This is unnecessary as the update flag will be checked internally in ntreeUpdateTree anyway, except for the generic bNodeTreeType->update callback (it could even be harmful by preventing necessary updates that don't use the ntree->update flag). Executing this once after loading a node tree is a useful feature for pynodes, so they can do initial verification.

code cleanup: minor BMESH_TODO's, some were left in even though they were done/invalid.

Fix for bundle adjusting with motion restricted

This commit bundles new libmv version from own branch
which brings fix for wrong parameter block used for
modal solver parameterization.

Fixes #34985: Crash with Motion tracker (Tripod Motion)

Cycles: optimization for 3D viewport border render with heavy scenes, the OpenGL
render of objects could slow things down when redrawing the view each time a new
sample is displayed.

Now it does a partial redraw of the viewport with only the render border area,
skipping OpenGL object drawing while the render is refining.

Cycles / Non-Progressive integrator:
* Subsurface samples were not taken into account for the Sobol directions table.

BGE: Cleaning up BL_ShapeDeformer's use of Blender's Key. This also fixes a bug with replicas (added objects) crashing when using shape keys.

Freestyle stroke rendering is now done before lens flare. Suggested by Ton on IRC.

edits to startup.blend
- temp dir /tmp --> /tmp/
- set sequencer cache limit from 128 --> 1024
- set sequencer view to RGB --> RGBA

Fix for r55961 which revered texture icons fix at r55499

Reported by Antony Riakiotakis, thanks!

== FFMPEG / Canon DSLR footage workaround ==

The latest ffmpeg versions include a workaround to deal with a certain
pecularity in Canon DSLR footage: instead of decoding pictures with the
proper resolution of 1920x1080 they decode it with 1920x1088 and add a
black bar at the bottom.

Needless to say, that this screws up things in a lot of areas within blender
(proxy indices, mask animations etc.)

Since all blender versions besides Linux x86 32bit seem still to include
older ffmpeg versions which still contain this bug, this patch adds
a workaround for older versions until we have all versions on all platforms
up to date.

code cleanup: minor changes, clang checker option for exact size matches and use vector functions.

correct pyapi function intersect_line_sphere_2d() using 3d vecs when only 2d are needed.

fix for tangent curve flipping only doing 2d angle tests.

Texture stencil:

Robustness: Avoid translating the stencil outside the active area. Helps
to avoid losing the stencil somewhere in bitspace.

Usability: Take image repeat mapping and scaling into account when
fitting stencil aspect. Togglable by operator properties.

Shader nodes / order:
* Have all "Info" nodes next to each other.
* Moved "Material Output" to the top.
* Have all light shaders (Emission, Background, AO) next to each other.

Node Toolbar:
* Use column() layout, this way it uses a bit less space.

Node Socket UI:
* Fix for Min/Max labels, they started with a lower-case character.

minor speedup to BM_mesh_normals_update()

Fix for #34910, NodeGroup input/output sliders bug. Initially i thought this was a limitation of the "only 1 list per panel supported" type, but this has since been fixed. Lists just need an additional identifier to distinguish lists in the same panel, thanks to Bastien Montagne for the uiList overhaul!

use UNLIKELY macro for frequently called inline bli math functions.
