Saving with only a filename (from Python) wasn't being prevented,
while it would successfully write the file to the working-directory,
path remapping and setting relative paths wouldn't work afterwards
as `Main.filepath` would have no directory component.
Disallow this since it's a corner case which only ever occurs
when path names without any directories are used from Python,
the overhead of expanding the working-directory for all data saving
operations isn't worthwhile.
The following changes have been made:
- bpy.ops.wm.save_mainfile() without a filepath argument
fails & reports and error when the file hasn't been saved.
Previously it would write to "untitled.blend" and set the
`G.main->filepath` to this as well.
- bpy.ops.wm.save_mainfile(filepath="untitled.blend")
fails & reports and error as the filename has no directory component.
- `BLI_path_is_abs_from_cwd` was added to check if the path would
attempt to expand to the CWD.
Revert part of the fix from 073669dd85
that initialized the file-path on first save as it's no longer needed.
Also remove relbase argument to BLI_path_normalize as the destination
file paths shouldn't use relative locations.
In almost all cases there is no difference between `G.relbase_valid`
and checking `G.main->filepath` isn't an empty string.
In many places a non-empty string is already being used instead of
`G.relbase_valid`.
The only situation where this was needed was when saving from
`wm_file_write` where they temporarily became out of sync.
This has been replaced by adding a new member to `BlendFileWriteParams`
to account for saving an unsaved file for the first time.

The difference between G.save_over and G.relbase_valid was minor.
There is one change in functionality. When saving the default-startup
file from an already loaded blend file - future save actions will
continue to write to the originally loaded file instead of prompting
the user to select a location to save the file.
This change makes saving the startup file behave the same way
"Save a Copy" does.

Use "filepath" which is the current convention for naming full paths.
- Main use "name" which isn't obviously a file path.
- BlendFileData & FileGlobal used "filename" which is often
used for the name component of a path (without the directory).
Basically, this fixes disappearing previews when editing asset metadata
or performing undo/redo actions.
The preview generation in a background job will eventually modify ID
data, but the undo push was done prior to that. So obviously, an undo
then would mean the preview is lost.
This patch makes it so undo/redo will regenerate the preview, if the preview
rendering was invoked but not finished in the undone/redone state.
The preview flag PRV_UNFINISHED wasn't entirely what we needed. So I had to
change it to a slightly different flag, with different semantics.
If the blend file is saved from a script in another thread,
like the render thread for example, Blender will crash on the call that
redraws the UI.

Compressing blendfiles can help save a lot of disk space, but the slowdown
while loading and saving is a major annoyance.
Currently Blender uses Zlib (aka gzip aka Deflate) for compression, but there
are now several more modern algorithms that outperform it in every way.
In this patch, I decided for Zstandard aka Zstd for several reasons:
- It is widely supported, both in other programs and libraries as well as in
general-purpose compression utilities on Unix
- It is extremely flexible - spanning several orders of magnitude of
compression speeds depending on the level setting.
- It is pretty much on the Pareto frontier for all of its configurations
(meaning that no other algorithm is both faster and more efficient).
One downside of course is that older versions of Blender will not be able to
read these files, but one can always just re-save them without compression or
decompress the file manually with an external tool.
The implementation here saves additional metadata into the compressed file in
order to allow for efficient seeking when loading. This is standard-compliant
and will be ignored by other tools that support Zstd.
If the metadata is not present (e.g. because you manually compressed a .blend
file with another tool), Blender will fall back to sequential reading.
Saving is multithreaded to improve performance. Loading is currently not
multithreaded since it's not easy to predict the access patterns of the
loading code when seeking is supported.
In the future, we might want to look into making this more predictable or
disabling seeking for the main .blend file, which would then allow for
multiple background threads that decompress data ahead of time.
The compression level was chosen to get sizes comparable to previous versions
at much higher speeds. In the future, this could be exposed as an option.

Change compared to previous buggy commit (rBf8d219dfd4c31) is that
new `BlendFileReadReports` reports are now passed to the lowest level
function generating the `FileData` (`filedata_new()`), which ensures
(and asserts) that all code using it does have a valid non-NULL pointer
to a `BlendFileReadReport` data.
Sorry for the noise, it's always when you think a change is trivial and
do not test it well enough that you end up doing those kind of
mistakes...
