This patch adds a new operator to convert a black and white image into
grease pencil strokes.
If the image is not B/W, an internal conversion is done.
This is the first operator using Potrace, but we expect to add more features in next Blender versions.

Using context overrides in Python caused problems for any operator that
changed the context and require these changes to be read back.
CTX_wm_area_set() for e.g. would set the struct member but future
calls to CTX_wm_area() would still return the value defined by Python
callers context overrides.
This also resolves a mismatch between polling and calling operators
from Python, where poll would override the Python context where calling
only overrode the context when a new context was passed in.
Printing an evaluated view layer would show:
Evaluated Scene 'Scene'
- Now __repr__ uses the __str__ fallback for evaluated data,
as done in other situations where we can't create a string that
would evaluate to the data.
- __str__ now shows when the data is evaluated.
- __str__ always includes the memory address
(which was previously only shown for structs without a name).
Move arguments to BLO_library_link_{begin/named_part/end} into
a single parameter struct, to ensure arguments always match.
This allows is to skip tagging ID's LIB_TAG_DOIT when it's not needed,
previously it was always cleared just in case it was needed.
This also makes it possible to remove BLO_library_link_named_part_ex
which was only used when tagging was needed.
Based on the original patch by Vaishnav S (@padthai), this adds
support for temperature units. Initially supported units are Celsius,
Kelvin, and Fahrenheit.
The units aren't used anywhere with this commit. Those changes should
happen in separate patches by adding PROP_TEMPERATURE to RNA property
definitions. But it should be ensured that the various solvers and
simulations actually properly use real units.
The complexity of some of the changes comes from the fact that these
units have offsets from each other as well as coefficients. This also
makes the implementation in the current unit system troublesome.
For example, entering 0C evaluates correctly to 273K, but 0C + 0C
doubles that result, because each unit value is evaluated separately.
This is quite hard to solve in the general case with Blender's current
unit system, though, so it is not handled in this commit.

This commit renames 'execute' to 'run' because:
- This follows Python's "PyRun" which these functions wrap.
- Execution functions can use either exec/eval modes,
making naming awkward (for future API refactoring).
This was committed as a temporary workaround in 82150f5641
as release builds were failing (only debug builds worked).
This adds `stdio.h` to the header which is now split into a file that
contains more specialized functionality.
Also move function body inside BPY_python_backtrace,
removing PyC_StackPrint as we have PyC_StackSpit() for
similar functionality that can be called from a debugger.
This replaces header include guards with `#pragma once`.
A couple of include guards are not removed yet (e.g. `__RNA_TYPES_H__`),
because they are used in other places.
This patch has been generated by P1561 followed by `make format`.

There is a parameter typo in Python API document about bpy.props.StringProperty.
This patch fixes this.
Also this patch should apply to 2.90 branch as well.

As creator.c is used for the 'main' function,
avoid obscure declarations being placed so prominently.
- Move Blender as a Python module declarations into it's own section.
- Move USD declaration to an 'extern' just before it's called.
Showing the Python error without any explanation is often
not enough information and doesn't hint that the error was in the
user input.
The error report from a invalid expression such as '..1' used to be:
('invalid syntax', ('<string>', 1, 1, '..1'))
Now reads:
Error evaluating number, see Info editor for details: invalid syntax
