Fix #33223: Instant Crash on Window minimize

Issue was caused by manipulating with triple buffers of minimized window.
It's more like an Intel driver bug but we can workaround it in quite clear
way by skipping draw of minimized windows.

Fix #33229: Blender crashes on finishing render

Windows Libs: move OpenEXR headers to same directory structure as other platforms.

Scons: better fix for OSL compiler path, so it also works on OS X.

Implementation of string lookup functions for collections in the C API. These were declared in RNA_blender.h but not actually implemented in the respective *_gen.c files.

use input and output slots for bmesh operators, needed for the python api to get return values.

SCons: make OSL linking work on windows, and fix OSL compiler path issue to
properly expand to absolute path.

Localization should not depend on debug locale library

Linking happens fine, but blender crashes on startup -- crash with familiar
backtrace happens with i18n disabled (in that case it's something to do with OIIO).

OSX/scons: refine oslc compile workaround

OSX/cmake: py 3.3 migration

Basic work for an ALL_STATIC option, to enable when you want to build blender in a portable way. Still WIP!

No boost system when we have own compiled version!

OSX/scons: migration to py 3.3

Fix when statically linking with distro's boost: in this case, we most likely also need to statically link against icu, as most boost packages are built with it. Without that, you get a bunch of errors at link time (when using boost_locale, or, in freestyle branch, boost_regex).

So when you enable Boost_USE_STATIC_LIBS, you should also set Boost_USE_ICU to True. Will add a note about that in build doc too.

Definitive fix for version_ge with equal versions like "1.0.0" and "1.0".
Also fixed DEB boost version checking, own fault.
And disabled building ocio's apps, else it would go searching for an oiio lib (and we have not yet built ours) - anyway, if users want them, they can build them on their own!

improvements to bevel
- the resulting selection is now correct

internal details
- bev_rebuild_polygon() now only rebuilds polygons that are attached to a bevel vertex (was rebuilding ALL).
... need to take care we don't leave faces pointing to removed geometry, so far this works fine.

- bev_rebuild_polygon() uses stack memory for <32 size ngons to reduce allocs.

- skip hash lookup when removing bevel verts (use tag instead).

bmesh: BM_verts_in_face was using bmesh operator flag which is no longer ensured to be available,
use internal apiflag instead, Thanks to Nicholas Bishop for spotting.

also quiet some warnings.

Merged changes in the trunk up to revision 52340.

BGE: The Step Height for a character physics controller is now set to 0.01, which means that Step Height can no longer be 0, which causes issues such as those noted in issue #33221, "KX_CharacterWrapper inconsistencies and error," reported by Angus Hollands (agoose77). I've also added a do_versions() fix that will give objects with 0 Step Height sane defaults. This means old files will now work better with character physics.

BGE: Changing "transform_uv" -> "transformUV" in some error messages.
