Small typo fix for tooltip of FModifier.blend_out

Cheers to "Lockal" for finding this one!

Fixed crash when tracking several tracks manually

Crash was caused by non-threadsafe guarded allocatio which becomes
threadsafe only when thread was started using BLI_threads module.

2 new bevel options for the operator and the modifier.

* even offset, uses same shell distance method as solidify to give even with beveled faces.
* distance offset, this is mostly for compatibility with the modifier in trunk which uses the bevel width as a distance rather then a percentage. at the moment this is awkward for the operator since it makes percent act differently where the 0-1 range doesnt make sense.

still need to bring back more options from trunks bevel modifier.

Buildbot tweaks:
- Enable SSE/SSe2 for 64bit builds
- Build CUDA binaries

formatting and minor refactor of some bmesh functions.
* BM_Make_Quadtriangle --> BM_Make_Face_QuadTri_v
* BM_Make_QuadTri --> BM_Make_Face_QuadTri

save 4 bytes per BMLoop, added some comments on index use.

Fix #29594: cycles NaN values with window coordinates mapping.

non functional changes & de-duplicate yet another face center function

Cycles: require Experimental to be set to enable CUDA on cards with shader model
lower than 1.3, since we're not officially supporting these. We're already not
providing CUDA binaries for these, so better make it clear when compiling from
source too.

remove BLI_blenlib since its not needed in quite a few bmesh files

formatting and variable rename edits only.

OSX: proper scons config and linking weak for jackOSX and errorhandling

svn merge ^/trunk/blender -r42564:42586

correction to report message

add WM_operator_call_notest() for operators that need to call themselves within invoke functions without being freed.

Fix #29603: Mode switch on linked objects

Do not allow to enter to weight paint mode for proxied objects.

fix [#29537] file/save crashes when target path isnt found

bug was that uiPupMenuSaveOver(...) could run the WM API call function which freed the operator, within the low level invoke function which kept using the freed memory.

Changed uiPupMenuSaveOver(...) to only show a popup so the caller needs to check if the file exists and should be immediately written (which was done everywhere except for blend saving anyway).

* added note that operators invoke/exec funcs cant call WM_operator_call(...) on themselves, ends up using freed memory.
* added BLI_is_file(path), checks the file exists and isnt a directory.

Fix #29600: Hook actions wrong Tool Shelf adjust

Do not register hook_assign and hook_remove operators in the redo panel.

Fix #29599: Side of Active tool not working in Faces/Edges

Added warning message if there's no last selected vertex in the selection stack.

slight improvement to bevel, when using the edges to take the new vertex location into account, dont let the longer edge skew the new position.

also include an new & improved vertex placement method but left commented for now.
