Crash was happening on windows platforms only and was caused
by some specifics about how CRT works.
Basically, blender and all of the .dll are compiled with /MT
flag, which means blender.exe and all .dll are using separate
environments. This makes it impossible to pass file descriptors
from blender to other dll, because it becomes invalid in the dll.
And this is exactly what was happening: OIIO was trying to open
movie file with all known plugins and one of them was zlib. And
the way OIIO was using zlib API is opening the file using Boost
and passing a file descriptor to zlib. And since zlib was a
dynamic library this lead to general issues using this descriptor
in zlib code.
Solved by linking to zlib statically. This allows to safely pass
file descriptor to zlib API. Alternative would be to compile all
the stuff with /MD flag, but that's much bigger and less robust
way to fix the issue.
Tested on windows using msvc2008, scons plus cmake both 32 and 64
bit versions. Seems to be working fine.
Further tweaks for mingw and msvc2012 could be needed tho.
* Better handling of "multiarch" python stuff (libs also need two different paths).
* Fix Opencollada default paths.
Hopefully this won't break anything...
Added new build option WITH_JACK_DYNLOAD for CMake and
WITH_BF_JACK_DYNLOAD for SCons, which means there'll be
no build-time linking against libjack and getting symbols
from libjack will happen runtime using dlopen and dlsym
tricks.
Alternative would be to use weak linking, but it'll require
having wrapper for preloading libjack.
This new options are disabled by default and they only
intended to be used on linux. Other platforms shall not
be using this and there shall be no functional changes
on non-linux platforms at all.
* Deprecate computing capability 1.3 (sm_13)
This commit disables auto build of sm_13 CUDA platform, which means that starting with Blender 2.67, we don't support sm_13 devices anymore. It has become difficult to support that and it was already feature incomplete (no render-passes, AO, Multi Closure etc).
It's still possible to manually enable sm_13 for own tests, but building might break in the future.
You served well and now desired retirement, but you'll always live in our hearts.
And for sure -- monument!

Some notes:
- Removed all code which was from inside ifdef WITH_COMPOSITOR_LEGACY
- Removed some functions which were used by old compositor only but
weren't ported to new color management
- Removed WITH_COMPOSITOR_LEGACY from build systems
- node_composite_util.h was in fatc used by compo nodes specification
files, so added it back to cmake.
Could be cleaned up by moving header files to files where they're
actually needed but would consider this is a separate task.
- Should be no functional changes!
It's intended to perform compilation of CUDA kernels only,
without doing anything with other sources/resources and
main purpose of this target is to be able to compile cuda
kernels in completely different environment than the rest
of blender was compiled.
This is needed for linux build environment, where sm_13
compilation fails dramatically in 32bit chroot but could
be compiled in 64bit environment.
This should make it easier to write user-config.py
Still not sure how to deal with OSL and LLVM in a nice way, they're currently
using some hacks which didn't support specifying this libraries as static.
