Before this change the Features() method would return a different Fs
to that the Features() method was called on if the remote was
instantiated on a file.
The practical effect of this is that optional features, eg `rclone
about` wouldn't work properly when called on a file, and likely this
has been causing low level problems for users of these backends for
ages.
Ideally there would be a test for this, but it turns out that this is
really hard, so instead of that all the backends have been converted
to not copy the Fs and a big warning comment inserted for future
readers.
Fixes#2182
Use the same function to join the root paths for the wrapping remotes
alias, cache and crypt.
The new function fspath.JoinRootPath is equivalent to path.Join, but if
the first non empty element starts with "//", this is preserved to allow
Windows network path to be used in these remotes.

Make Hashes() return the intersection of all the hashes supported by the remotes
When moving a directory in drive, most of the time only a notification
for the directory itself is created, not the old or new parents.
This tires to find the old path in the dirCache and the new path with
the dirCache of the new parent, which can result in two notifications
for a moved directory.
Add a new flag to the drive backend to allow document conversions oni upload.
The existing --drive-formats flag has been renamed to --drive-export-formats.
The old flag is still working to be backward compatible.
Make use of the mime package to find matching extensions and mime types.
For simplicity, all extensions are now prefixed with "." to match the
mime package requirements.
Parsed extensions get converted if needed.
Before this change on Windows, files copied locally could become
heavily fragmented (300+ fragments for maybe 100 MB), no matter how
much contiguous free space there was (even if it's over 1TiB). This
can needlessly yet severely adversely affect performance on hard
disks.
This changes uses NtSetInformationFile to pre-allocate the space to
avoid this.
It does nothing on other OSes other than Windows.
Add --drive-v2-download-min-size flag to allow downloading files via the
drive v2 API. If files are greater than this flag, a download link is
generated when needed. The flag is disabled by default.
When combining the remote value and the root path, preserve the absence
or presence of the / at the beginning of the wrapped remote path.
e.g. a remote "cloud:" and root path "dir" becomes "cloud:dir" instead
of "cloud:/dir".
