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.
7413031dd6 introduced an error and related warning when generating Py API docs:
```
/blender/doc/python_api/sphinx-in/bpy.app.translations.rst:132: ERROR: Unexpected indentation.
...
/blender/doc/python_api/sphinx-in/bpy.app.translations.rst:132: WARNING: Lexing literal_block 'See :func:`pgettext` notes.' as "python3" resulted in an error at token: '`'. Retrying in relaxed mode.
```
Pull Request: https://projects.blender.org/blender/blender/pulls/123097
The new `pgettext_n` function (typically imported as `n_`) can be used
when there is a need to extract messages, without translating them. It
is essentially a no-op equivalent to the C++ version `N_`.
Just for the `pyrna_struct_keyframe_insert()` function, reduce the
reporting level of keyframe insertion failures from `RPT_ERROR` to
`RPT_WARNING`. This prevents the conversion of these reports to a Python
exception.
`CombinedKeyingResult::generate_reports()` now accepts an option
argument `report_level`, so that the caller is in control over the type
of reports it generates.
Previously only errors were converted to exceptions; warnings were
implicitly cleared and never displayed. To avoid these 'keyframe
insertion failure' reports from becoming invisible, the
`pyrna_struct_keyframe_insert()` function now sends any warnings to
stdout (unless there were errors, in which case the old
error-to-exception behaviour is still there).

The buttons to upgrade or sync extensions called extension
operators via bpy.app.handlers, requiring awkward glue-code
which didn't show error reports in to the user.
Remove these operators and call the upgrade & sync operators directly.
Support for "System" extensions as an alternative to the current
"User" extensions repository.
The purpose of this change is to support bundling extensions for
offline work or in environments where users setting up thier own
extensions isn't desirable, see #122512.
Details:
The default "System" repository on Linux will for example use:
- `/usr/share/blender/4.2/extensions/{system}` For system installs.
- `./4.2/extensions/{system}` For portable installs.
- Blender's default startup now has a "System" repository
which users or administrators may populate.
- Repositories can select between User/System paths,
setting a custom path overrides overrides this setting.
- Add "BLENDER_SYSTEM_EXTENSIONS" (matching "BLENDER_LOCAL_EXTENSIONS").
Ref !122832
The type for `bpy_struct.keyframe_insert()`'s `options` parameter was
instead applied to a non-existent `flag` parameter.
The description and type for `mathutils.Vector.Repeat()`'s `vector`
parameter was instead applied to a non-existent `tuple` parameter.
Also fix a reference to `BMElemeSeq` instead of `BMElemSeq`.
Ref: !122734
- Support passing in operator ID's using Python dot syntax.
- Support define operators that haven't yet been registered
matching Blender's own behavior.
Also add doc-string for bpy.types.Macro.define.
The "render_stats" handler now includes the message line that was
written to stdout as the first arg (using `BKE_callback_exec_string`
instead of just `BKE_callback_exec_null`).
This can be useful to track render progress (and people were relying on
parsing stdout in the past).
Was a request in chat.
This also corrects possible output from the callback being written in
between message parts in `do_write_image_or_movie` (which was probably a
mistake in 93d5e106aa).

Sometimes it is necessary to pass additional data through generic UI entities,
to specific implementations. For example to pass additional options to panel
polling & drawing when instantiating a panel through its panel type. Or storing
additional data in a button, without hardcoding it in the button struct/class.
Passing data via context is a simple solution to this, however so far this only
works using hardcoded context queries or RNA pointers. For passing arbitrary
strings we've used workarounds like creating an RNA type to wrap it already.
For example `RNA_AssetCatalogPath`, which is used to dynamically populate menu
items based on an asset catalog path, via a generic menu type.
type instantiation. This makes it possible to invoke specific asset shelves as
popover panels.
Idea is simply to let `bContextStore` entries hold copies of the string (as
`std::string`), avoiding lifetime issues. Context APIs are extended to support
setting/querying strings via a context member name.

Splash screen notification text:
- When starting in "Offline mode" with repositories with installed
packages enabled, the text is clickable unless launched with
`--offline-mode`, the tooltip notes that the command line setting
can't be changed at run-time.
- Don's show anything if there are not extensions installed.
Preferences:
- Don't show the welcome message on preferences if:
- Blender is online.
- The message was dismissed.
- There are no enabled remote repositories.
- The option to enable extensions.blender.org has been replaced with
a button that switches to the "System" tab where Online Access
can be enabled.
Also expose bpy.app.online_access_override needed for the UI to check
if online access was disabled using command line arguments.
Add a preference to "Work Offline" system preference as well as command
line options `--offline-mode` & `--online-mode`
(which overrides the preference).
This option is displayed in the initial setup screen too.
This is currently respected by:
- Check for updates on startup
- Disables running an update when enabling extensions.
When Blender is launched with `--offline-mode` the option cannot be
enabled in the preferences. This is intended for environments
where internet access is intentionally disallowed.
Background: with Blender supporting access to online-repositories
as well as 3rd party extensions themselves potentially accessing the
internet. This setting provides a way for users to disable online
functionality.
This prevents error messages when online access fails in environments
without internet access as well as the ability for users who prefer
Blender doesn't access the internet to have one place to turn this off.
While it does not enforce limitations on add-ons, 3rd party scripts
are expected to respect this setting using `bpy.app.internet_offline`.
The details for this will be handled along with other policies scripts
are expected to follow.

Move all header file into namespace.
Unnecessary namespaces was removed from implementations file.
Part of forward declarations in header was moved in the top part
of file just to do not have a lot of separate namespaces.

Handling of the blendfile handle freeing when linking data from a
blendfile requiring endianness conversion was totally broken, leading
to double-freeing attempts.
Guess that the fact that this was never reported shows how rare
'big-endian' blendfiles are nowadays... But we still have a few in our
test repo.
Regression in [0]. PyPreConfig.use_environment was internalized to 0
but PyConfig.use_environment wasn't.
Thanks to @unwave for finding the root cause.

Add _bpy._wm_capabilities(), needed for preferences code to check if
WM functionality is supported. This could be made into a public
function, see code comments for details.
Since upgrading to Python 3.11, errors (other than syntax errors)
no longer jumped to the location of the error as they used to.
This was caused by the line number being unset, relying on the
attribute access to return the actual value.
Resolve by using attribute access when the struct member can't be used.
The insert key function in `animrig/keyframing.cc` took a `ReportList`
argument which it used to print messages in case of failures.
Instead this now returns a `CombinedKeyingResult` and the caller is
responsible for creating reports out of that.
To make that simpler the `ID` argument has been changed from a pointer to a reference.
The calling functions now make sure that it's not a `nullptr`.
This has the effect that there will be less messages printed in the Info panel when e.g. inserting keys with a keyingset.
This still doesn't make an error message pop up though.

Add an optional keyword argument `keytype` to the
`rna_struct.keyframe_insert()` function.
This makes it possible to set the new key's type. The code for this was
almost all in place, the only thing that was missing was the RNA
wrapper, which is what this commit adds.
Example: `bpy.context.object.keyframe_insert("location",
keytype='JITTER')`
There is no backward compatibility issue here, because the argument is
optional and defaults to the previously hardcoded value of `KEYFRAME`.

While valid, this isn't so common and cppcheck warns about this,
use explicit casts to suppress the warning, also correct "true"
being assigned to a float value.
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.
