Previously, chown would exit immediately if there was an error
changing file ownership. We now print an error to stderr and
continue when an error occurs.
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 :^)
This patch returns an empty Optional<...> instead of an Error for
Core::System::getgrname and Core::System::getpwnam if we can't find a
matching group or user entry.
It also updates the 'chown' utility to support this new behavior.
