patch [#30689] select similar for metaballs
from Cyrille Ruggero (kalado) with some edits.

Fix building with scons

Can't actually test here so hope this is enough.

rigidbody: Use bullet's own fixed constraint

Should be no functional changes.

bullet: Update to version 2.82 (bullet revision 2705)

Remove patch that has been applied upstream.

Fixes several bugs.

drawobject: Fix sphere bounds drawing

Would draw ellipsoid instead, which is not so useful and wrong when
used for rigid body collision shape visualization.

svn merge -r59887:59888 ^/branches/soc-2013-rigid_body_sim

make the message for addons failing to parse a little more descriptive (suggested in report [#37196]).

OSX/CMake: fix ftemplate condition

Fix for occasional crashes due to numerical instability in Freestyle Perlin noise modifiers with a large 'octaves' value.
Problem report by Light BWK through personal communications, thanks a lot!

Fix #37175, Viewer node issue for newly toggled render passes.
The RenderLayers node would use the "combined" image result for all passes which don't have a valid render result yet. This causes problems when the buffer element size is not actually 4 floats (RGBA) as
with the 3 float normal passes. Also the result is rather meaningless then, so just keep the image buffer at NULL for unavailable passes, which will return plain (0,0,0) color.

Fix for OSL bug reported on IRC by Pablo Vasquez: Clamp option of the math node in OSL produces bad results. Really stupid bug, OSL math node was assigning the clamped 1st input value instead of the
clamped result of the actual operation.

fix for negated normal being used when using individual centers & normal orientation in vertex select mode.

code cleanup: minor transform refactor
redraw flag were mixing up types - int/char/bool, add enum type to use instead.

fix [#37179] All transformation normals drawn when proportional edit, individual origins and normal transform orientation are set
thanks to psy-fi for the initial patch.

refactor transform.c - minor changes
- use TREDRAW_HARD define
- use apply prefix for transform callbacks.
- make callbacks static.

style cleanup

Fix part 1 of #37177 spikes in sculpting.

Was a typo from refactor to calculate sculpt plane from forward facing
vertices only. The branch of the code that did the calculation would end
up with a nice division by a wrong number.

Making real need to remove proxies

Otherwise some invalid pointers will be left
which could be harmless if real object stays
local, but crashes when linking them to
another files.

Was discovered here in the studio during
Project Pampa, and the steps to reproduce are:

- Create lib.blend, put armature and cube to it.
Create a group with them.
- Create scene.blend and link group from lib.blend.
- Make a proxy from armature.
- Make group real.
- Add real objects to a group.
- Create comp.blend and link group from scene.blend.
This step will creah.

Bugfix: Renaming bones now renames the corresponding F-Curves in actions used by
Action Constraints

Ctrl+Alt+SelectMouse now does "Select all keyframes in same channel" in
DopeSheet too

Previously, it only worked in the Graph Editor, though I thought I had
implemented it here too.
