Issue was caused by de-referencing NULL pointer, rres did not have any
views because nothing was rendered yet.
Needs more closer look about where else such a de-reference could happen.
This replaces sequential ray moving followed with scene intersection with
single BVH traversal, which gives us all possible intersections.
Only implemented for CPU, due to qsort and a bigger memory usage on GPU
which we rather avoid. GPU still uses the regular bvh volume intersection code, while CPU now uses the new code.
This improves render performance for scenes with:
a) Camera inside volume mesh
b) SSS mesh intersecting a volume mesh/domain
In simple volume files (not much geometry) performance is roughly the same
(slightly faster). In files with a lot of geometry, the performance
increase is larger. bmps.blend with a volume shader and camera inside the
mesh, it renders ~10% faster here.

Object flags are depending on bounding box which is only available after
mesh synchronization.
This was broken since 7fd4c44 which happened quite close to the release
and oddly enough was not sopped by anyone. Render test is coming for this.
Was spotted by Thomas Dinges while working on another patch.
We can now scale from 32px up to 256px (default has been upgraded to 128px).
Thumbnails are now generated as 'large', i.e. 256px.
Previews are scaled up if necessary, unlike icons (for folders or files without preview images).
Note that .blend thumbnails themselves remain in 128px for now (they are embeded in .blend files,
not quite sure we want to make them four times bigger...).

Originally I wanted to get rid of RenderResult->rect* entirely, but it's
convenient to have for temporary structs.
This patch makes sure they are used only when really needed, which
should help clearing the code out.
(they are needed when using RE_AcquireResultImage() - which produces a
RenderResult with no RenderView)

CCFLAGS are used for both C and C++ compilers and one is better not to pass
C-related flags to C++ compiler. C-compiler flags are to be passed via CFLAGS
variable.
