- We were using primitive versions of mkstemp and mkdtemp, they have
been converted to use LibCore::System.
- If an error occurred whilst creating a temporary directory or file, it
was thrown and the program would crash. Now, we use ErrorOr<T> so that
the caller can handle the error accordingly
- The `Type` enumeration has been made private, and `create_temp` has
been "split" (although rewritten) into create_temp_directory and
create_temp_file. The old pattern of TempFile::create_temp(Type::File)
felt a bit awkward, and TempFile::create_temp_file() feels a bit nicer
to use! :^)
Once the Core::Filesystem PR is merged (#17789), it would be better for
this helper to be merged in with that. But until then, this is a nice
improvement.
About half of the usages were not using `force` anyways, and the other
half presumably just got confused about what "force" really means in
this context (which is "ignore nonexistent files").
The only 'legitimate' user, which is `rm`, instead now handles this
completely internally instead.
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)
