Update ceres to current upstream version

Brings fixes for BLAS.

Bundle adjustment improvements

- Get rid of rotation matrix parameterization,
  use angle-axis instead.

  Also Joined rotation and translation into a
  single parameter block.

  This made minimization go significantly faster,
  like 1.3x times in average.

- Fix first camera when bundling. This is to
  address orientation ambiguity.

  Reconstruction result could still vary in
  size, but that's another issue to be addressed
  later.

Additional change:

Split EuclideanBundleCommonIntrinsics into
smaller functions, so it's now a bit easier
to follow.

Fix #34875: 0 digits of precision was not supported for FloatProperty, now
you can specify precision=0 for this, and use -1 for the default 2.

Compatibility and robustness:

* Make masking depend on texture mode only if there's an actual texture
present
* New stroke system uses diameter to calculate stroke spacing, while old
texture painting brushes and system used radius. So divide spacing of
brushes in old files to half. Since I expect trunk users to have already
adapted this, I do this for an old subversion of blender.

Fix #34921: cycles rendered a specific scene with a small high poly object
contained in a large low poly object very slow, due to failure case of fast
multithread BVH binning. Tweaked parameter now to avoid this.

Attempt to fix a potential name conflict between Freestyle and the compositor.

A crash in the Freestyle renderer was reported by Ton on IRC with a stack trace
below.  Note that #2 is in Freestyle, whereas #1 is in the compositor.  The problem
was observed in a debug build on OS X 10.7 (gcc 4.2, openmp disabled, no llvm).

Apparently a name conflict between the two Blender modules is taking place.
The present commit hence intends to address it by putting all the Freestyle C++
classes in the namespace 'Freestyle'.  This revision will also prevent potential
name conflicts with other Blender modules in the future.

Special thanks to Lukas Toenne for the help with C++ namespace.

Pressing Ctrl+R when blender was built without bullet would crash.
- add checks so rigid-body operators only return FINISHED when they make some changes to the scene.
- remove (scene == NULL) checks, poll already catches these.

rigidbody operators poll functions were mixing up CTX_data_active_object/ED_object_active_context.
- replace ED_operator_rigidbody_add_poll with ED_operator_object_active_editable_mesh
- replace ED_operator_rigidbody_active_poll with ED_operator_scene_editable for operators that use the entire selection.
- remove rigid-body from objects that are converted from meshes to curves, while this isnt crashing it is confusing to see in the UI.

Various edits preparing addons' translations tools (not everything yet functionnal/tested, though).

Also workaround a nasty bug, where unregistered py classes remain listed in relevant __subclasses__() calls, which would lead to crash with python addons i18n tools (main translation was not affected, as messages extracting tools are executed in a brand new "factory startup" Blender ;) ).

Fix #34740: cycles rendering issue mixing glossy/glass BSDF's with zero or very
low roughness and same index of refraction.

Problem was bad float precision due to low roughness, which caused the pdf for
the different closures to not match properly.

Fixes for sequencer effects

- Add and subtract effects will now affect on only RGB channels,
  and alpha of first input is used as an alpha for the result.

  Also solved creepyness with straight->premul->straight conversion
  in byte versions of add/subtract.

- Solved issue with multiply modifier, which lead to white*white
  not being white (was off by 1.0/255) due to wrong optimization
  of division by 255 with shr by 8.

  According to Ton this issue goes back to 2000!

This fixes #34811: Wrong result of add/subtract effects

Live window resizing on Windows
Custom implementation for resizing (GHOST_SizerWin32)

Some things still don't work:
* esc cancel
* max windows size
* aero (sizing) snap on win7

hbrBackground = 0 to disable clear screen.

Thanks to dfelinto for help in finding of root cause.
