b856b6010e PyAPI: buffer protocol support for mathutils types
Adding buffer protocol support increases the speed of copying a Vector
(3D) array into a `numpy.array` by up to x3.8.

25c69382fc Fix: frozen mathutils Vector & Matrix types could be resized
It's important that frozen types are immutable, add a generic
check that mathutils types can be resized and check the frozen flag.

Also correct the exception types when Vector's cant be resized,
using a ValueError instead of a TypeError as the type is correct.

ddeddaecd6 PyDoc: improve mathutils python signatures and doc-strings
- Adding `/` to signatures to indicate that arguments are accepted only
  as positional.
- Document default values and optional arguments in consistent way with
  other docs.
- Use `Literal` for strings to indicate set of allowed string values
  (later it can also be used in typing stubs).
- Document some undocumented arguments.

3bcfb151c1 PyDoc: use Python's type annotation syntax for doc-strings
Replace plain-text type information with the type syntax used
for Python's type annotations as it's more concise, especially for
callbacks which often didn't include useful type information.

Note that this change only applies to inline doc-strings,
generated doc-strings from RNA need to be updated separately.

Details:

- Many minor corrections were made when "list" was incorrectly used
  instead of "sequence".
- Some type information wasn't defined in the doc-strings and has been
  added.
- Verbose type info would benefit from support for type aliases.

094f7235bb Cleanup: replace own Py_INCREF_RET with CPython's Py_NewRef
These are both simple functions that serve the same purpose.
Py_NewRef didn't exist when Py_INCREF_RET was added to Blender.

c3247aa4f0 Refactor: Move BPY generic headers to proper C++ ones.
NOTE: `bgl.h` was left unchanged, as it is deprecated code anyway, and
its conversion to C++ does not seem immediately trivial.

4fac7828e4 Refactor: Move BPY mathutils headers to proper C++ ones.
This module actually was confusing, since only a few headers were
effectively still C ones (using the `extern "C"` blocks)...

8144252aa9 Fix return types in docs for matrix.zero, quat's .negate and .identity
Noticed in mathutils docs (and in python type hinter for mathutils) some methods doesn't return anything though docs stated that they return themselves and fixed the docs.

7436b578dd Cleanup: force wrapping all uses of PyDoc_STRVAR
Without this, minor edits can re-indent the whole doc-string at a
different level, causing diffs to be unnecessary noisy.

0618de49ad Cleanup: Replace MIN/MAX macros with C++ functions
Use `std::min` and `std::max` instead. Though keep MIN2 and MAX2
just for C code that hasn't been moved to C++ yet.

e955c94ed3 License Headers: Set copyright to "Blender Authors", add AUTHORS
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

d973355b3a Cleanup: reduce amount of math-related includes
Using ClangBuildAnalyzer on the whole Blender build, it was pointing
out that BLI_math.h is the heaviest "header hub" (i.e. non tiny file
that is included a lot).

However, there's very little (actually zero) source files in Blender
that need "all the math" (base, colors, vectors, matrices,
quaternions, intersection, interpolation, statistics, solvers and
time). A common use case is source files needing just vectors, or
just vectors & matrices, or just colors etc. Actually, 181 files
were including the whole math thing without needing it at all.

This change removes BLI_math.h completely, and instead in all the
places that need it, includes BLI_math_vector.h or BLI_math_color.h
and so on.

Change from that:
- BLI_math_color.h was included 1399 times -> now 408 (took 114.0sec
  to parse -> now 36.3sec)
- BLI_simd.h 1403 -> 418 (109.7sec -> 34.9sec).

Full rebuild of Blender (Apple M1, Xcode, RelWithDebInfo) is not
affected much (342sec -> 334sec). Most of benefit would be when
someone's changing BLI_simd.h or BLI_math_color.h or similar files,
that now there's 3x fewer files result in a recompile.

0777c1861e Cleanup: ignore GCC cast-function-type warning for PyMethodDef's
While these warnings point to real errors in the code,
PyMethodDef are an exception where functions with different numbers
of arguments are all cast to the same function type.
