5616c7a058 Cycles: disable scaling up of ray differentials after diffuse/glossy bounce, this 
isn't working well for OSL texture filtering and wasn't very helpful to begin
with, a better solution should be possible.

to OpenGL/CUDA/OSL rendering.

188718a3d5 OSL Shader Files: 
* Simplify default color values, where each component was the same.
* Initialize closures as Null Closure, rather than assigning an existing closure, gets overwritten anyways.

38dcce2da2 FIX: OSL mix shader clamps 2nd color component to 3rd one. 
Previously the OSL Mix shader node was clamping the 2nd color component (green) to the 3rd color component (blue). Now every component is clamped on its own.

a9d889cba4 Fix #33405: preview render getting stuck in a particular .blend file, ObjectKey 
operator< had wrong brackets, changed it now to be more clear.

Fix #33404: crash GPU rendering with OSL option still enabled. There was a check
to disable OSL in this case, but it shouldn't have modified scene->params because
this is used for comparison in scene->modified().

41f98978e3 Fix cycles issue when NaN is used for RGB ramp, can access array out of bounds then. 
OSL noise() function is generating NaN's in certain cases, fix for that goes to our
OSL branch.

Also add missing minimum weight and max closure checks to OSL, forgot to add these
when fixing another bug.

of via thread local storage, and creating ustrings for attribute lookup.

0d6976ad0c Fix #32900: object motion blur not working on the GPU. To make this work I disabled motion 
blurring of scale animation, probably not a big loss in practice since it's not so common
to animate this, can be added back later.

ceed3ef640 Fix #32907: failure rendering a complex node setup, hitting fixed max number

the mix weights are fed into the closure nodes directly.

5c6f6301b0 Image thread safe improvements 
This commit makes BKE_image_acquire_ibuf referencing result, which means once
some area requested for image buffer, it'll be guaranteed this buffer wouldn't
be freed by image signal.

To de-reference buffer BKE_image_release_ibuf should now always be used.

To make referencing working correct we can not rely on result of
image_get_ibuf_threadsafe called outside from thread lock. This is so because
we need to guarantee getting image buffer from list of loaded buffers and it's
referencing happens atomic. Without lock here it is possible that between call
of image_get_ibuf_threadsafe and referencing the buffer IMA_SIGNAL_FREE would
be called. Image signal handling too is blocking now to prevent such a
situation.

Threads are locking by spinlock, which are faster than mutexes. There were some
slowdown reports in the past about render slowdown when using OSX on Xeon CPU.
It shouldn't happen with spin locks, but more tests on different hardware would
be really welcome. So far can not see speed regressions on own computers.

This commit also removes BKE_image_get_ibuf, because it was not so intuitive
when get_ibuf and acquire_ibuf should be used.

Thanks to Ton and Brecht for discussion/review :)
