Use context manager for reading addon headers

Fix: a broken symlink to an addon resulted in a blank addon tab

The addons tab in the User Settings window would be empty, due to
a FileNotFound error. This error can be caused by a broken symlink,
which is now treated the same was as a file that misses its bl_info
dictionary.

Fix T44989: Crash on linking external OSL material

Issue was caused by passing NULL bmain to the path remap function when
localizing the node tree.

Paths are to be remapped, otherwise mapping of paths to OSL scripts
might happen in a wrong way.

Cycles: Fix crash doing render preview of external OSL script

Cycles: Move requested feature conversion to an own function

This way it could be used for the shader/baking kernels easily n the future.
making those kernels more optimal.

Cycles: Remove round-up trickery for max closure in split OpenCL kernel

Round-up was only enabled for viewport render, which was for a long time hardcoded to
use 64 closures. This was done in order to avoid unnecessary kernel re-compilations
when tweaking the shader tree.

We could enable selective closure compilation in the viewport later if it'll give
measurable speed improvements, but even then round-up is to happen outside of the
device level,

This commit also removes early output which happened in cases when max closure did
not change. It was wrong because other requested kernel features might have been
changed.

Cycles: Remove requirement of using experimental kernel for hair and blur on AMD

Those features are not selectively compiled, so there's no real benefit of hiding
them under the experimental feature set.

Cycles: Make hair, object and motion blur selective compiled into OpenCL

This features are now based on the scene settings, so scenes without those features
used are rendered even faster.

This gives about 30% speedup on the AMD A10 APU here, but at the same time it does
not mean such an improvement will happen on all the hardware. That being said, the
Tonga device here seems to have no measurable difference.

In any case it seems handy to have for the future, when we'll want to support SSS
in the kernel or to port selective compilation/split kernel to CUDA devices.

Fix "View All" operation in image space not available with locked interface

Fix T44995: Crash loading packed image

Alternative fix copying windows from popup dialogs

It could still crash if the window was freed and another was activated. see T44688.

Fix T44991: Apply transform skips poly-radius

rename wiki -> manual

Fix T44984: wrong texture clamping when applying saturation > 1.0

Applying saturation > 1.0 in HSV space easily leads to negative values in RGB space,
so we have to clamp again...

Don't show smoke domain when render-only enabled
