Regression from [0] where the key-map was attempting to load preferences
for key-map items for add-on operators which were not yet defined.
Resolve by postponing keymap updating until after loading add-ons.

Regression caused by [0]. Resolve by adding a 'keep_properties' argument
to KeyConfig.update so the key-map items can be restored after the
operators have been reloaded.

Since [0] modal transform in the 3D viewport caused key-maps to be
rebuilt by the event system. Creating a temporary copy for
ViewOpsData_Utility flagged the key-map as outdated.
This could crash (resolved by [1] - for the most-part), but would still
rebuild the whole key-map, adding unnecessary overhead.
This would also reset the KMI_EXPANDED flag, causing transform
to hide key-map items when using Blender with the key-map editor open.
Add a function to temporarily suppress key-map updates.
While not ideal, full support for temporary key-maps that behave
differently to user key-maps is a bigger project for something
that's only needed in one place.

C++ callers must ensure the arguments are valid,
reserve validity for the RNA API for raising errors.
This is already the case for most RNA API calls that wrap BKE API's.
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.
