The `pre` handler is called after blender internal code is done populating
the link/append context with data to be processed, and before this data
starts being linked from library files.
The `post` handler is called after blender is done linking, and
potentailly appending and/or instantiating, the requested data and all
of their dependencies.
Both handlers are called with a single argument, the link/append
context.
An new RNA sets of wrappers have been added to expose relevant info from
these internal C++ structures.
NOTE: !113658 is very similar (but tied to asset drag & drop), whereas
this PR is more general (these could probably live hand-in-hand / side-
by-side).
Implements #122357

Some quick py example code:
```python
import bpy
def my_handler_pre(lapp_context):
print("About to {}:\n\t".format("link" if "LINK" in lapp_context.options else "append"),
"\n\t".join("{} '{}', from libs ['{}']".format(item.id_type, item.name,
"', '".join([l.filepath for l in item.source_libraries]))
for item in lapp_context.import_items))
def my_handler_post(lapp_context):
print("{}:\n\t".format("Linked" if "LINK" in lapp_context.options else "Appended"),
"\n\t".join("{} '{}', from lib '{}'".format(item.id.id_type, item.id.name, item.source_library.filepath)
for item in lapp_context.import_items))
bpy.app.handlers.link_append_pre.append(my_handler_pre)
bpy.app.handlers.link_append_post.append(my_handler_post)
```
Disable dynamic SDL loading as well as disable SDL for release builds.
This was only used for audio output which can already use OpenAL
if there are back-ends not natively supported by Blender.
- Remove extern/sdlew/
- Remove the WITH_SDL_DYNLOAD build option.
- Remove `bpy.app.sdl.available`.

Accessing `bl_rna` for type defined in `scripts/modules/bpy_types.py`
could return their parent-classes RNA when accessed via their parent
types __subclasses__() method.
The type of an RNA types "bl_rna" should be `bpy.types.Struct`,
it was being set to the type it represented so:
`type(bpy.types.Object.bl_rna) == bpy.types.Object`
which wasn't correct.

Use snake style naming for all the kernel nodes functions.
Omit kernel prefix in the names since of the using namespace.
Use full forms of the terms
('iter' -> 'iterator', 'ntree' -> 'node_tree', 'rem' -> 'remove', ...).

Previously, values for `ID.flag` and `ID.tag` used the prefixes `LIB_` and
`LIB_TAG` respectively. This was somewhat confusing because it's not really
related to libraries in general. This patch changes the prefix to `ID_FLAG_` and
`ID_TAG_`. This makes it more obvious what they correspond to, simplifying code.

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.
Calling `foreach_get/set` on a collection property did not trigger
a property update. In the attribute API, this lead to missing
updates after e.g. setting the values of an attribute.
This adds a call to `RNA_property_update` for the getter/setter
bpy rna function and adds a property update callback to all the
different attribute collection properties.

Match function and declaration names, picking names based on
consistency with related code & clarity.
Also changes for old conventions, missed in previous cleanups:
- name -> filepath
- tname -> newname
- maxlen -> maxncpy
No functional changes intended.
This simplifies the arguments for the `delete_keyframe` function.
The `bAction *` was always a `nullptr` so I just removed it.
The rna path char array and the array index were merged into the `RNAPath` struct.

Regression from [0], drivers were tagged as being disabled with a flag
that was never cleared. Causing the label to be displayed for files
where the expressions were enabled and in use.
Resolve by clearing this flag on file load and when re-compiling
expressions - since an expressions block flag may be cleared if it
becomes a simple expression.

This commit moves generated `RNA_blender.h`, `RNA_prototype.h` and
`RNA_blender_cpp.h` headers to become C++ header files.
It also removes the now useless `RNA_EXTERN_C` defines, and just
directly use the `extern` keyword. We do not need anymore `extern "C"`
declarations here.

When using a python expression, its execution is disabled by
default unless specified differently in the user preferences.
Previously this only produced the error
"Error: Invalid Python expression". However that isn't really the correct error.
Now the error reads "Python restricted for security".
I've added a new flag to the driver `DRIVER_FLAG_PYTHON_BLOCKED` that is set
if the driver can't run because python is blocked

BPY `library.write` has been moved to new PartialWriteContext code a few
weeks ago, removing this call to `BKE_blendfile_write_partial_end` was
somehow missed then.
This makes code behind the `bpy.data.libraries.write()` API use the new
`PartialWriteContext` class, instead of the old
`BKE_blendfile_write_partial` API.
NOTE: This also means that the `blendfile_io` tests using this python
API are now using the new class.
No behavioral changes are expected here.

The issue was that the Python keyframing code was already resolving the
RNA path fully to the owning ID, but then erroneously passing the
non-ID RNA pointer (in this case the sound sequence pointer) to the
keyframing code with that fully resolved path.
Notably, it wasn't just the VSE keyframing that was broken: keying any
non-ID structs via the Python API was broken. A good example is pose
bones: the Python keyframing code was resolving e.g. "location" on
the bone to "pose.bones["Bone"].location", but then passing that
path along with the pose bone struct to the keyframing code. Since
that fully resolved path of course doesn't exist on the bone itself,
keying would fail.
This fixes it by simply passing the owning ID's RNA pointer instead,
which it should have been doing in the first place.

The current temperature unit adjusts to Celsius or Fahrenheit based on
unit system, but specifically for color temperatures the convention is
to display them in Kelvin, and it'd be strange to e.g. see 11240°F when
opening the white balance panel.
Therefore, this adds a dedicated Color Temperature unit, and uses it
for the two existing blackbody temperature inputs in shader nodes.
