- Use API calls to access frame-data as PyFrameObject is now opaque.
- Update opcodes allowed for safe driver evaluation.
**Details**
Some opcodes have been added for safe-driver evaluation.
Python 3.11 removes many opcodes - the number of accepted opcodes in
Blender's listing dropped from 65 to 43) however some new opcodes
also needed to be added. As this relates to security details about newly
added opcodes have been noted below (see [0] for full documentation).
Newly added opcodes:
- CACHE:
Used to control caching instructions.
- RESUME:
A no-op. Performs internal checks.
- BINARY_OP:
Implements the binary and in-place operators,
replacing specific binary operations.
- CALL, PRECALL, KW_NAMES:
Used for calling functions, replacing some existing opcodes.
- POP_JUMP_{FORWARD/BACKWARD}_IF_{TRUE/FALSE/NONE/NOT_NONE}.
Manipulate the byte-code counter.
- SWAP, PUSH_NULL.
Stack manipulation.

Differential Revision: https://developer.blender.org/D15155
Regression caused by [0] that caused the error message to be
created based on a normalized exception (which hid line numbers).
PyC_ExceptionBuffer{_Simple} & BPy_errors_to_report
no longer clears the exception.
This could have been resolved by changing python_script_error_jump
however that would involve changes to reference counting that are more
risky (noted in code-comment).

Python exceptions are now shown in the info editor,
this also resolves an old bug where errors were printed twice.
This was originally based on D9752 by @ShadowChaser although many
changes have been made from the original patch.
Details:
- BPy_errors_to_report no longer prints additional output.
- BKE_report_print_test was added so it's possible to check if calling
BKE_report also printed to the stdout.
- Callers to BPy_errors_to_report are responsible for ensuring output
is printed to the stdout/stderr.
- Python exceptions no longer add a trailing newline,
needed to avoid blank-space when displayed in the info-editor.
Use a shorter/simpler license convention, stops the header taking so
much space.

While most of the source tree has been included
- `./extern/` was left out.
- `./intern/cycles` & `./intern/atomic` are also excluded because they

- filename comparison was invalid
- was stopping on the first traceback, which would reference the caller but not the error line (when the error was in a function).
