This also removes DirIterator::error_string(), since the same strerror()
string will be included when you print the Error itself. Except in `ls`
which is still using fprintf() for now.
Our `find` utility makes use of the `dirent::d_type` field for filtering
results, which `Core::DirIterator` didn't expose. So, now it does. :^)
We now store the name and type of the entry as the "next" value instead
of just the name. The type is exposed as a `DirectoryEntry::Type`
instead of a `DT_FOO` constant, so that we're not tied to posixy
systems, and because proper enums are nice. :^)
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 :^)
We previously had at least three different implementations for resolving
executables in the PATH, all of which had slightly different
characteristics.
Merge those into a single implementation to keep the behaviour
consistent, and maybe to make that implementation more configurable in
the future.
An explicit move constructor is required to null-out the moved-from
directory descriptor. Otherwise, we would call closedir() twice when
using ErrorOr<DirIterator>::release_value().
