Having includes in debug builds makes it possible to accidentally
break release builds.
Avoid this by moving calls to other modules out of BLI_assert.h
into BLI_assert.c
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.
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.

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.

Also remove the code in the ghash that is no longer used.
This change simplifies the existing code.

When building without TBB use native to the platform spin lock
implementation. For Windows it is an atomic-based busy-wait,
for Linux it is pthreads' spin lock.
For macOS it is a mutex lock. The reason behind this is to stop
using atomics library which has been declared deprecated in SDK
version 10.12. So this changes fixes a lot of noisy warnings on
the newer SDK.

Needs to compile with `CMAKE_OSX_DEPLOYMENT_TARGET` of 10.14 at least to
have `std::optional<>::value()` available. So we have to increase the
minimum required compiler version, but that requires more changes. Just
fix the build error for now.
