This renames the struct `Sequence` to `Strip`.
While the motivation for this partially comes from
the "Sequence Design" #131329, it seems like this
is a good refactor whether the design gets implemented
or not.
The `Sequence` represents what users see as strips in the
VSE. Many places in the code already refere to a `Sequence`
as "strip". It's the C-style "base class" of all strip types.
This also renames the python RNA type `bpy.types.Sequence`
to `bpy.types.Strip` which means that this technically breaks
the python API.

Large int64_t values were calculated and assigned int however the
calculation was performed on integer types which would truncate the
result before casting to an in64_t.
Regression in [0] which would cause ensuring the slash to do nothing
in most cases. Note that the slash may not be needed, but that should
be handled separately.

In some/many cases, an `ImBuf` is allocated, and all the pixels are
immediately filled by some code. Doing the memory clear within allocation
is just memory traffic for no good reason.
Add a flag to skip initialization of ImBuf pixels (IB_uninitialized_pixels)
and use that in some parts of VSE effects/rendering/cache/scopes, as well
as image loading code.

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.
