What was happening is that when Move was implemented as Copy + Delete,
MoveFile was seeing the files didn't need transferring (because they
were identical) then deleted the source.
The fix uses Move instead and patches onedrive to disallow a case
folded identical copy (which errors with 500 error)
* -vv or --log-level DEBUG
* -v or --log-level INFO
* --log-level NOTICE (default)
* -q --log-level ERROR
Replace Config.Verbose and Config.Quiet with Config.LogLevel

Multiple directories (up to --checkers worth) are scanned at once.
This uses much less memory than the previous scheme - only the amount
of memory needed to hold an entire directory listing of objects.
For directory based remotes the speed is unchanged.
For bucket based remotes, instead of doing one API call to list the
whole bucket, it does multiple calls, one for each pseudo directory.
However these are done in parallel so in practice this seems to speed
up directory listings.
This replaces the existing sync method as it performs faster and uses
less memory.
The old sync method is available with the temporary --old-sync-method
flag.

Optional interfaces are becoming more important in rclone,
--track-renames and --backup-dir both rely on them.
Up to this point rclone has used interface upgrades to define optional
behaviour on Fs objects. However when one Fs object wraps another it
is very difficult for this scheme to work accurately. rclone has
relied on specific error messages being returned when the interface
isn't supported - this is unsatisfactory because it means you have to
call the interface to see whether it is supported.
This change enables accurate detection of optional interfaces by use
of a Features struct as returned by an obligatory Fs.Features()
method. The Features struct contains flags and function pointers
which can be tested against nil to see whether they can be used.
As a result crypt and hubic can accurately reflect the capabilities of
the underlying Fs they are wrapping.
