strings.Title has been deprecated since Go 1.18 and an alternative has been
available since Go 1.0. The rule Title uses for word boundaries does not handle
Unicode punctuation properly. Use golang.org/x/text/cases instead.
Most of the time this will make no difference to user logs, however
the difference may be visible in JSON logs and on the rare occasions
src and dst are pointing to different file names.
Existing version did save username in config, but only when entering the custom
device/mountpoint sequence in config. Regardless of that, it did always look up the
username at startup with an api request.
This commit improves it so that the username will always be stored in config,
and when using standard authentication it picks it from the login token instead of
requesting it from the remote api, and also in fs constructor it picks it from config
instead of requesting it from remote api (again).
This change ensures we call the Shutdown method on backends when
they drop out of the fs/cache and at program exit.
Some backends implement the optional fs.Shutdowner interface. Until now,
Shutdown is only checked and called, when a backend is wrapped (e.g.
crypt, compress, ...).
To have a general way to perform operations at the end of the backend
lifecycle with proper error handling, we can call Shutdown at cache
clear time.
We add a finalize hook to the cache which will be called when values
drop out of the cache.

This was caused by nested calls to NewTransfer/Done.
This fixes the problem by only incrementing transfers if the remote is
present in the transferMap which means we only increment it once.
