Implementation of lerp without a function requires repeating one of
the arguments, which is not ideal. To avoid that, add a new function
to the driver namespace. In addition, provide a function for clamping
between 0 and 1 to support easy clamped lerp, and a smoothstep function
from GLSL that is somewhat related.
The function implementations are added to a new bl_math module.
As an aside, add the round function and two-argument log to the
pylike expression subset.

Currently if you drag and drop an item from the outliner elsewhere in
the Blender window, the outliner will scroll the entire time, even if the
mouse is far away. This commit adds optional behavior for the edge pan
operator that makes it only act if the mouse is close enough to the region.

Those are useful when you have to create containers with static
storage duration. If those would use Blender's guarded allocator,
it would report memory leaks, that are not actually leaks.
This updates the usage of integer types in code I wrote according to our new style guides.
Major changes:
* Use signed instead of unsigned integers in many places.
* C++ containers in blenlib use `int64_t` for size and indices now (instead of `uint`).
* Hash values for C++ containers are 64 bit wide now (instead of 32 bit).
I do hope that I broke no builds, but it is quite likely that some compiler reports
slightly different errors. Please let me know when there are any errors. If the fix
is small, feel free to commit it yourself.
I compiled successfully on linux with gcc and on windows.
The move constructor of `mpq_class` from GMP currently
allocates when it is moved. So, it cannot be noexcept.
Since we want to use this type, this static assert cannot
stay there.
shobjidl_core.h only exists in the windows 10 SDK in the 8.1
SDK ShObjIdl.h will have the definitions we need, which still
exists in the 10 SDK and implicitly includes shobjidl_core.h.
so ShObjIdl.h will work on both SDK versions.
This adds `blender::RandomNumberGenerator` in `BLI_rand.hh`.
Furthermore, `RNG` is now implemented in terms of this new generator.
No functional changes are expected, the generated random numbers
are not changed by this commit.

This allows us to avoid many calls to `as_span()` methods. I will
remove those in the next commit. Furthermore, constructors
of Vector and Array can convert from one type to another now.
I tested these changes on Linux with gcc and on Windows.
This can be used to find separate islands in meshes efficiently (as is
done in cycles already). Furthermore, this helps to implement some
algorithms on node trees more efficiently.
This adds new callbacks to `bNodeSocketType` and `bNodeType`.
Those are used to generate a multi-function network from a node
tree. Later, this network is evaluated on e.g. particle data.

The MSVC atomic function is defined for an unsigned type.
Not sure why this became an issue after switch to TBB by default,
maybe some CFLAGS changed to be more strict after that.
The knife code currently calls the `BLI_bvhtree_overlap` function that
tests the overlap between the mesh tree and an AABB that encompasses the
points projected in the clip_start, clip_end and or clip_planes of the
view.
This resulted in many false positives since the AABB is very large.
Often all the triangles "overlapped".
The solution was to create a new function that actually tests the
intersection of AABB with a plane.
Even not considering the clip_planes of the view, this solution is more
appropriate than using overlap.

Searching in these files for "_as" will reveal a comment at the
top, that explains what these methods are for. There is no need
to duplicate that knowledge all over the place.
Also remove the code in the ghash that is no longer used.
This change simplifies the existing code.
