Expose arguments to use when creating a Python sub-process.
Python could fail to start when loaded in a customized environment,
with PYTHONPATH set for e.g. Blender ignores these and loads but a
Python sub-process attempts to use these environment variables which
may point to incompatible Python versions.
Resolve the root cause of #124731.
Regression in [0]. PyPreConfig.use_environment was internalized to 0
but PyConfig.use_environment wasn't.
Thanks to @unwave for finding the root cause.

Previously retrieving a collection from the context like "selected_ids"
would give a linked list of allocated items. Now it returns a vector of
RNA pointers. Though the number of items is typically fairly small,
using contiguous memory and avoiding many small allocations are
typical performance improvements that could still be beneficial
when there are many items. Iteration also becomes much simpler.

Extract:
- Operators' poll messages, including Python-defined ones.
- Use default translation context for the region toggle pie menu.
- Newly created F-Curve modifiers.
- Newly created video tracker track.
- Grease Pencil UV area status message
- Status messages in the graph slider operators.
- Status message "Text <text.py>" when opening .blend with
auto-executing Python file.
Disambiguate:
- Track: can mean NLA track, video tracking, a tracking marker, or
a track constraint.
- Tracking: can mean video tracking, or a track constraint.

The term `PIL` stands for "platform independent library." It exists since the `Initial Revision`
commit from 2002. Nowadays, we generally just use the `BLI` (blenlib) prefix for such code
and the `PIL` prefix feels more confusing then useful. Therefore, this patch renames the
`PIL` to `BLI`.

Resolve an error with SSL using a hard coded path to certificates on
Linux causing HTTPS access to fail.
request.urlopen(..) couldn't access any HTTPS URL's.
Previously BPY_python_end wasn't called when scripts called sys.exit()
because BPY_python_end exited the Python interpreter.
Change this behavior to call BPY_python_end without exiting the Python
interpreter while freeing Blender/Python data.
While leaks in the context of sys.exit aren't especially important
it's generally preferable for sys.exit() to match Blender's code-paths
for exiting to avoid unexpected behavior.
Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
Design task: #110784
Ref !110783.
Hydra is a rendering architecture part of USD, designed to abstract the
host application from the renderer. A renderer implementing a Hydra
render delegate can run in any host application supporting Hydra, which
now includes Blender.
For external renderers this means less code to be written, and improved
performance due to a using a C++ API instead of a Python API.
Add-ons need to subclass bpy.types.HydraRenderEngine. See the example in
the Python API docs for details.
An add-on for Hydra Storm will be included as well. This is USD's
rasterizing renderer, used in other applications like usdview. For users
it can provide a preview of USD file export, and for developers it
serves a reference.
There are still limitations and missing features, especially around
materials. The remaining to do items are tracked in #110765.
This feature was contributed by AMD.
