The fract function in OpenCL does more than just return the fraction.
It also writes the floor to the second argument. Which wasn't put
in consideration.
Instead, we use a simple `a - floor(a)` like the Math node.

The White Noise node hashes the input and returns a random number in the
range [0, 1]. The input can be a 1D, 2D, 3D, or a 4D vector.

Add Multiply, Divide, Project, Reflect, Distance, Length, Scale, Snap,
Floor, Ceil, Modulo, Fraction, Absolute, Minimum, and Maximum operators
to the Vector Math node. The Value output has been removed from operators
whose output is a vector, and the other way around. All of those removals
has been handled properly in versioning code.
The patch doesn't include tests for the new operators. Tests will be added
in a later patch.

Previously eigens internal include order somehow implicitly provided
M_PI and friends. The recent eigen version bump broke this implicit
behaviour, better to be explicit that we need the math defines for MSVC.
The clamp option is implemented using graph expansion, where a Clamp node
named "clamp" is added and connected to the output. So the final result
is actually from the node "clamp".

When calling `MEM_guarded_mallocN_aligned` with an alignment of 4,
a pointer that was returned that is 4 byte but not 8 byte aligned.
When freeing this pointer, `MEM_guarded_freeN` thinks that it is an
illegal pointer, because it asserts that `((intptr_t)memh) & 0x7 == 0`.
The fix is to always use at least 8 byte alignment.

- Implement dynamic inputs. The second input is now unavailable in single
operand math operators.
- Reimplemenet the clamp option using graph expansion for Cycles.
- Clean up code and unify naming between Blender and Cycles.
- Remove unused code.

This could happen e.g. when changing smoke type from flow to domain or
connecting a volume shader with to a domain without an actual flow type
around.

If the option is enabled, the output is clamped to the target range.
The target range is [To Min, To Max]. The option is enabled by default.
The clamp option is implemented in EEVEE by linking to the `clamp_value`
GLSL function. And it is implemented in Cycles using a graph expand
function.

We can add more fine grained checks for when these flags are supported so
that adding asan flags manually still has all the workarounds, but for now
compiling succesfully is more important.
The issue was caused by a limitation of GetNumaNodeProcessorMask():
on systems with more than 64 processors, this parameter is set to the
processor mask for the node only if the node is in the same processor
group as the calling thread. Otherwise, the parameter is set to zero.
Patch from Max Dmitrichenko, thanks!
It's extremely slow to compile and run, so just disable it unless
WITH_CYCLES_KERNEL_ASAN is manually enabled. For Clang it's always
enabled since that appears to work ok.
This also limits the -fno-sanitize=vptr flag to the Cycles kernel, as it
was added specifically to work around an issue there.

The partial disabling was causing issues with Clang and ASAN, and it seems we
don't need to restrict it to the kernel anymore now that we are no longer using
boost directly.
The issue is that wayland seems to impose a generic device naming scheme
when using Xwayland For example any table stylus will show up with the
following naming convention: xwayland-stylus:33
For this to work in blender, I had to modify how the identifier string
is extracted. I also renamed the two char pointers in the search
algorithm to be more logical.

During viewport rendering where the viewport samples are set to 0 the UI

The code was missing some checks for whether keyframe selection
went successfully and whether reconstruction has been successfully
initialized.
The interface still gives quite generic message, with the details
printed to the console. This can be addressed separately.
The issue was caused by un-initialized local storage for volume
intersection hits which are supposed to be stored in per-thread
KernelGlobals.
Fix is to make thread_shader() be the same as thread_render() in
respect of KernelGlobals.

The issue was in the optimization code path for opaque shadow rays
which was wrongly considering all primitives in the node to have
same visibility flags.
We want users to go to the current version for their current version
when possible if not point to latest.
/dev should really only be for development related work. End users
should not be browsing /dev unless they are reading about upcoming
features ahead of time.
Before this change doing something like `--verbose 10 --debug-cycles`
did not properly set verbosity, only using those arguments in an other
way around was leading to a correct verbosity level.
