The hash tables and vector blenlib headers were pulling many more
headers than they actually need, including the C base math header,
our C string API header, and the StringRef header. All of this
potentially slows down compilation and polutes autocomplete
with unrelated information.
Also remove the `ListBase` constructor for `Vector`. It wasn't used
much, and making it easy to use `ListBase` isn't worth it for the
same reasons mentioned above.
It turns out a lot of files depended on indirect includes of
`BLI_string.h` and `BLI_listbase.h`, so those are fixed here.

Although I don't like the idea of using owning raw pointers in new APIs
like this (violates fundamental C++ good practises), this type is mostly
meant for writing to files via DNA. So we have to use Blender's memory
management via the guarded allocator here.
Considered making this an alternative function, but then we'd have to
duplicate logif or duplicate memory or so. Not worth it to me.
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
Ref !110783.
A lot of files were missing copyright field in the header and
the Blender Foundation contributed to them in a sense of bug
fixing and general maintenance.
This change makes it explicit that those files are at least
partially copyrighted by the Blender Foundation.
Note that this does not make it so the Blender Foundation is
the only holder of the copyright in those files, and developers
who do not have a signed contract with the foundation still
hold the copyright as well.
Another aspect of this change is using SPDX format for the
header. We already used it for the license specification,
and now we state it for the copyright as well, following the
FAQ:

No user visible changes expected.
For brush assets, we need a way to store a reference to a brush in .blend files, so that the last active brush can be restored from the file. See #101908. It seems like a generally useful thing to have.
Adds a new DNA struct to store a "weak" asset reference, that is, a reference that can break under a number of circumstances, but should work reliably enough under normal usage. There's no way to reliably reference an asset currently, so this works on a "best effort" basis. It can break when assets are moved inside the asset library, asset libraries are unregistered from the Preferences, or a file is opened on a different machine with different Preferences, for example. It can also break currently if an asset library is renamed.
It contains:
- Information to identify the asset library the asset can be found in.
- A relative "identifier" (currently a relative path) for the asset within the asset library.
There's further code to resolve a weak reference to file paths and Blender library paths.
Part of #101908.
