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
Address issue raised by T78913.
Implementation of lerp without a function requires repeating one of
the arguments, which is not ideal. To avoid that, add a new function
to the driver namespace. In addition, provide a function for clamping
between 0 and 1 to support easy clamped lerp, and a smoothstep function
from GLSL that is somewhat related.
The function implementations are added to a new bl_math module.
As an aside, add the round function and two-argument log to the
pylike expression subset.

Custom driver functions need access to the dependency graph that is
triggering the evaluation of the driver. This patch passes the
dependency graph pointer through all the animation-related calls.
Instead of passing the evaluation time to functions, the code now passes
an `AnimationEvalContext` pointer:
```
typedef struct AnimationEvalContext {
struct Depsgraph *const depsgraph;
const float eval_time;
} AnimationEvalContext;
```
These structs are read-only, meaning that the code cannot change the
evaluation time. Note that the `depsgraph` pointer itself is const, but
it points to a non-const depsgraph.
FCurves and Drivers can be evaluated at a different time than the
current scene time, for example when evaluating NLA strips. This means
that, even though the current time is stored in the dependency graph, we
need an explicit evaluation time.
There are two functions that allow creation of `AnimationEvalContext`
objects:
- `BKE_animsys_eval_context_construct(Depsgraph *depsgraph, float
eval_time)`, which creates a new context object from scratch, and
- `BKE_animsys_eval_context_construct_at(AnimationEvalContext
*anim_eval_context, float eval_time)`, which can be used to create a
`AnimationEvalContext` with the same depsgraph, but at a different
time. This makes it possible to later add fields without changing any
of the code that just want to change the eval time.
This also provides a fix for T75553, although it does require a change
to the custom driver function. The driver should call
`custom_function(depsgraph)`, and the function should use that depsgraph
instead of information from `bpy.context`.

This must match the specified number in enum items, and is supported for both
static and dynamic enums. Previously dynamic enums did not support a default
value at all.
When "Relative Remap" option was added, the intention was only to remap
paths that were already relative. However it remapped all paths.
This was reported as T62612 and fixed recently,
however some Python script authors depended on the old behavior.
For users, it's reasonable to use the existing operators to make paths
absolute/relative. For scripts however it's useful to be able to write
out individual data-blocks with the ability to make all paths relative.
Now `bpy.data.libraries.write()` takes a path_remap argument which can
be `NONE/RELATIVE/RELATIVE_ALL/ABSOLUTE` allowing the script author to
choose how paths are handled when writing out data-blocks.
Addresses T77768.
