Since the tangent attributes are now recomputed inside the loop over uv
layers, looping directly over this mesh data is dangerous, as computing
the tangents attributes might trigger some re-allocations, leading to
invalid memory accesses when accessing the next uv layer.
Solved by caching uv layers' names in a list beforehand, the uvlayers
themselves are not even needed for tangent data handling.
Regression from e0a9e98cbd.
Only last tangents layer was written to all tangent layers before this fix.
Code before fix evaluate tangents for all layers into mesh loops data (which keeps data only for one layer) and then writes information about 'each' layer which is actually only the last one.
Code after fix evaluates tangents in the beginning of the loop that exports tangent data so that data for correct layer is being written into fbx.

Enums in Blender evaluate to a string, so trying to add them to a pose
failed with an error because FCurves only accept numbers.
The fix is to modify the data path and split the property name off.
By evaluating that we arrive at the bone, from which we can call `get(property_name)`
to get the int value.

The logic to generalize over downloading a URL or reading data from
the file-system included static values in the iterator along with the
data being read - so the caller could access the total expected size of
the data being read. While this worked, the result didn't read well.
Now these iterators yield the data being read, a new type has been
added for the caller to read the size hint from.
Also correct invalid doc-string.
Accessing the internal extensions command would warn that the processes
stdout wasn't closed on completion. While it's harmless at the moment,
ensure it's closed using a context manager.
Regression in [0] caused extensions with an empty wheel list
to raise an unhandled exception when extracting the Python
version from the wheel list.
Besides resolving this error, account for errors using the wheel
list since it isn't type checked in this code-path.

Add error handling for rare but possible failures on installation.
- Account for the destination extension directory being a file.
- Handle the exception if renaming the temporary directory fails.
When an extension could could be removed but it's directory could be
renamed, the install operation would fail anyway.
Resolve by completing the installation when the directory can be moved.

The FBX SDK specifies that normals should use the IndexToDirect FBX
reference mode. This mode allows data written to FBX to be deduplicated
by writing a separate array of indices into the deduplicated array of
data that can be used to reconstruct the full array of data.
When Unity imports per-vertex normals with the IndexToDirect reference
mode, it erroneously considers the imported mesh's normals invalid if
any of its normals were deduplicated. This issue is not present in other
external software that I have tested.
This patch modifies the export of per-vertex normals to not perform any
deduplication, avoiding the issue in Unity's FBX importer while
maintaining use of the IndexToDirect reference mode.
The add-on's patch version has been increased.

addon_utils.enable/disable now handle wheels so that the functions can
be used with extension add-ons.
A new argument `refresh_handled` supports scripts handing refresh
themselves which is needed to avoid refreshing many times in cases
when there are multiple calls to enable/disable.
This is mostly useful for internal operations.
Support multiple extensions with different Python versions in a similar
way to how "platforms" are handled now.
This will be needed when Blender upgrades to a newer version of Python
so extensions which have a binary dependency on Python 3.11 don't
attempt to install in a Blender built with a newer Python version.
Details:
- Extensions from incompatible Python versions are not listed.
- Python versions are extracted from wheel names.
- An extension may include wheels for multiple Python versions,
only the compatible wheels will be installed.
- Links may include a "python_versions" field which is checked
when dropping into Blender.
- JSON generated by the "server-generate" command include the:
"python_versions" field for extensions that include wheels.
- The "python_versions" field is optional, when omitted no version
checks are performed.
Also correct watch_test make target.
