Fix T78959: Show current frame indicator when interface is locked

When the playhead drawing moved to an overlay, a check was added to keep
it from drawing with a locked interface. This is necessary for some overlays,
but not this one, so this removes the check, making it the responsibility of
the editor.

A context function is added to make that check easier in the future.

Fluid: Numpy support for Mantaflow build system

Adjusted the fluid build system so that plugins that depend on numpy can be compiled as well.

Note that in this commit numpy support is still disabled. It can be enabled by re-running the Mantaflow update script with USE_NUMPY=1 and enabling WITH_MANTA_NUMPY in extern/mantaflow/CMakeLists.txt. This will happen in a future commit.

Cleanup: avoid static initialization order issues when accessing CPPTypes

Instead of depending on static initialization order of globals use
static variables within functions. Those are initialized on first use.
This is every so slighly less efficient, but avoids a full class of problems.

Simulation: move initial simulation code from bf_blenkernel to bf_simulation

I removed bf_blenkernel from `nodes/CMakeLists.txt` again (added it yesterday),
because now this was causing me unresolved symbol errors... Without it, cmake
seems to link the libraries bf_simulation, bf_blenkernel and bf_nodes in the right
order. Not sure if that is just luck or if it is guaranteed.

It was possible to fix the issue by using cmakes `LINK_INTERFACE_MULTIPLICITY`,
but that is probably bad style.

Fix T77867: Link Duplicate Object crashes during batch creation

When using link duplicated objects it could happen that one object is
calculating the GPUBuffers and the second object is marking these
buffers invalid. This introduces threading issues.

This patch fixes this by combining the surface and surface per material
batches. Most likely the surface per material batches are used and when
requested you will most likely need the surface batch for the depth
tests and overlays.

During tests it slightly improves performance as batches aren't thrown
away without using it.

After this patch we can add a quick path for meshes with one material
and two materials.

Alternative approaches that have been checked:
- sync extraction per object: reduced performance to much (-15%)
({D8292})
- post checks: reduced the threading issues, but didn't solve it.
- separating preparation and execution of the extraction ({D8312})

Nodes: move some code from blenkernel directory to nodes

This also introduces the `blender::nodes` namespace. Eventually,
we want to move most/all of the node implementation files into
this namespace.

The reason for this file-move is that the code fits much better
into the `nodes` directory than in the `blenkernel` directory.

Tests: disable ASAN when discovering tests

CMake, when it's configuring the project, runs the `blender_test` test
runner (if it exists from a previous build) to discover which tests it
contains. At this time none of the tests themselves are run, so it's not
that useful to run ASAN and have it break things when there are memory
leaks.

This commit disables ASAN by injecting `ASAN_OPTIONS="detect_leaks=0"` in
the environment variables.

It is not enough to use `set(ENV{ASAN_OPTIONS} "detect_leaks=0")` in
`tests/gtests/runner/CMakeLists.txt`, as it wouldn't be passed to the child
process.

Tests: move tests from USD test directory into `io/common` and `io/usd`

This commit is a followup of {D7649}, and ports the USD tests to the new
testing approach. It moves test code from `tests/gtests/usd` into
`source/blender/io/common` and `source/blender/io/usd`, and adjusts the
use of namespaces to be consistent with the other tests.

I decided to put one test into `io/usd/tests`, instead of
`io/usd/intern`. The reason is that this test does not correspond with a
single file in that directory; instead, it tests Blender's integration
with the USD library itself.

There are two new CLI arguments for the Big Test Runner:

- `--test-assets-dir`, which points to the `lib/tests` directory in the
SVN repository. This allows unit tests to find test assets.
- `--test-release-dir`, which points to `bin/{BLENDER_VERSION}` in the
build directory. At the moment this is only used by the USD test.

The CLI arguments are automatically passed to the Big Test Runner when
using `ctest`. When manually running the tests, the arguments are only
required when there is a test run that needs them.

For more info about splitting some code into 'common', see
rB084c5d6c7e2cf8.

No functional changes to the tests themselves, only to the way they are
built & run.

T73268: Link C/C++ unit tests into single executable

This commit introduces a new way to build unit tests. It is now possible
for each module to generate its own test library. The tests in these
libraries are then bundled into a single executable.

The test executable can be run with `ctest`. Even though the tests
reside in a single executable, they are still exposed as individual
tests to `ctest`, and thus can be selected via its `-R` argument.

Not yet ported tests still build & run as before.

The following rules apply:

- Test code should reside in the same directory as the code under test.
- Tests that target functionality in `somefile.{c,cc}` should reside in
`somefile_test.cc`.
- The namespace for tests is the `tests` sub-namespace of the code under
test. For example, tests for `blender::bke` should be in
`blender::bke:tests`.
- The test files should be listed in the module's `CMakeLists.txt` in a
`blender_add_test_lib()` call. See the `blenkernel` module for an
example.

macOS: Support arm64 architecture.

Enabling all `make deps` dependencies with the exception of Embree and OIDN.
After that, Blender can be compiled on an Apple Silicon Mac just like on any
Intel based Mac. There are still compiler warnings that need to be
investigated and there are probably a couple of bug still to be discovered
and to be fixed.

Most patches to the dependencies are simple and are about disabling SSE and
setting the proper architecture to compiile for. Notable exception is Python,
where I back ported a yet to be accepted PR for upstream Python:
https://github.com/python/cpython/pull/21249

Cross compiling or buliding a Universal Binary is not supported yet.
The minimum macOS target version for x86_64 remains at 10.13, the target
for arm64 is 11.00.

PointCloud: Initial rendering support for Workbench

Also includes outline overlays. Removes the temp overlay drawing

We make the geometry follow camera like billboards this uses less
geometry. Currently we use half octahedron for now. Goal would be
to use icospheres.

This patch also optimize the case when pointcloud has uniform radius.
However we should premultiply the radius prop by the default radius
beforehand to avoid a multiplication on CPU.

Using geometry instead of pseudo raytraced spheres is more scalable as
we can render as low as 1 or 2 triangle to a full half sphere and can
integrate easily in the render pipeline using a low amount of code.

Fix T78747: Fix mesh boundary detection and automasking

This issue was produced by a hack in the sculpt mode code from 2.80
when the sculpt API for connectivity info was not available.
The smooth brush was the only brush that needed connectivity info,
so there were 3 different smooth functions with the connectivity
queries implemented for dyntopo, meshes and grids. The mesh version
of smoothing was checking the number of connected faces to a vertex
to mask the mesh boundaries, which was not covering all cases and
was hardcoded in the smooth function itself.

This patch removes all those legacy functions and unifies all
smooth functions into a single one using the new API and the
automasking system. In order to achieve this, there were needed
some extra changes:

- The smooth brush now does not automasks the boundaries by default,
so its default preset needs to be updated to enable automasking

- The mesh boundary info is extracted once and cached in a
bitmap, similar to the disconnected elements IDs. This makes
boundary detection work as expected in all cases, solving a lot
of known issues with the smooth brush. In multires, this info is
extracted and cached only at the base mesh level, so it is much
more memory efficient than the previous automasking system.

- In order to keep the brushes responsive as they were before,
the automasking system can now skip creating the cache when it
is not needed for the requested options. This means that for
high poly meshes and simple automasking options the brushes
won't lag on start.

Python API: new RNA property `Screen.is_scrubbing`

This commit adds a new read-only boolean property `Screen.is_scrubbing`.

The related property `Screen.is_animation_playing` is set to `True` in
two situations:

- Animation is actually playing (for example via the Play button in the
timeline)
- The user is scrubbing through time (in the timeline, dopesheet, graph
editor, etc.)

To distinguish between these two cases, the property
`Screen.is_scrubbing` has been added.

Concept approved by @brecht.

VSE: Python API, allow creation of VSE Movie strips with missing file

It was already possible to create Sound and Image strips that reference
non-existing files. Now it's also possible to create Movie strips
referencing missing files via the Python API call
`Sequences.new_movie()`. In this case, the duration of the strip will be
set to 1 frame.

Note that this commit does not change anything in the user interface.

The Python API of the `MovieStrip` class is extended with a function
`reload_if_needed()`. This function only performs disk I/O if the movie
strip cannot produce frames, that is either when its filepath points to
a non-existing file, or when the video sequence editor has not been
shown yet (for example because it is in an inactive workspace).

This allows for the following:

```
import bpy

scene = bpy.context.scene
vse = scene.sequence_editor_create()

filepath = bpy.path.abspath('//demo.mkv')
strip = vse.sequences.new_movie("movie", filepath,
channel=2,
frame_start=47,
file_must_exist=False)
strip.frame_final_end = 327
```

This will create a new movie strip, even when `demo.mkv` does not exist.

Once `demo.mkv` has appeared at the expected location, either
`strip.reload_if_needed()` or `strip.filepath = strip.filepath` will
load it.
