bff702a6f1 docs: group the global flags and make them appear on command and flags pages
This adds an additional parameter to the creation of each flag. This
specifies one or more flag groups. This **must** be set for global
flags and **must not** be set for local flags.

This causes flags.md to be built with sections to aid comprehension
and it causes the documentation pages for each command (and the
`--help`) to be built showing the flags groups as specified in the
`groups` annotation on the command.

aaadb48d48 vfs: keep virtual directory status accurate and reduce deadlock potential
This changes hasVirtual to an atomic struct variable that's updated on
add or delete from the virtual map.

This keeps it up to date and avoids deadlocks.

fc798d800c vfs: fix backends being Shutdown too early when startup takes a long time
Before this change if the VFS took more than 5 to initialise (which
can happen if there is a lot of files or a lot of files which need
uploading) the backend was dropped out of the cache before the VFS was
fully created.

This was noticeable in the dropbox backend where the batcher Shutdown
too soon and prevented further uploads.

This fixes the problem by Pinning backends before the VFS cache is
created.

7771aaacf6 vfs: fix writing to a read only directory creating spurious directory entries
Before this fix, when a write to a read only directory failed, rclone
would leav spurious directory entries in the directory.

This confuses `rclone serve webdav` into giving this error

    http: superfluous response.WriteHeader

This fixes the VFS layer to remove any directory entries where the
file creation did not succeed.

9a9ef040e3 vfs: fix reload: failed to add virtual dir entry: file does not exist
This error happened on a restart of the VFS with files to upload into
a new directory on a bucket based backend. Rclone was assuming that
directories created before the restart would still exist, but this is
a bad assumption for bucket based backends which don't really have
directories.

This change creates the pretend directory and thus the directory cache
if the parent directory does not exist when adding a virtual on a
backend which can't have empty directories.

e405ca7733 vfs: make uploaded files retain modtime with non-modtime backends
Before this change if a file was uploaded to a backend which didn't
support modtimes, the time of the file read after the upload had
completed would change to the time the file was uploaded on the
backend.

When using `--vfs-cache-mode writes` or `full` this time would be
different by the `--vfs-write-back` delay which would cause
applications to think the file had been modified.

This changes uses the last modification time read by the OS as a
virtual modtime for backends which don't support setting modtimes. It
does not change the modtime to that actually uploaded.

This means that as long as the file remains in the directory cache it
will have the expected modtime.

28a8ebce5b vfs: fix rename of directory containing files to be uploaded
Before this change, if you renamed a directory containg files yet to
be uploaded then deleted the directory the files would still be
uploaded.

This fixes the problem by changing the directory path in all the file
objects in a directory when it is renamed. This wasn't necessary until
we introduced virtual files and directories which lived beyond the
directory flush mechanism.

143285e2b7 vfs: fix incorrect modtime on fs which don't support setting modtime
Before this change we were using the Precision literally to round the
precision of the mod times.

However fs.ModTimeNotSupported is 100y on backends which don't support
setting modtimes so rounding to 100y was producing very strange
results.

46b080c092 vfs: Fix IO Error opening a file with O_CREATE|O_RDONLY in --vfs-cache-mode not full
Before this fix, opening a file with `O_CREATE|O_RDONLY` caused an IO error to
be returned when using `--vfs-cache-mode off` or `--vfs-cache-mode writes`.

This was because the file was opened with read intent, but the `O_CREATE`
implies write intent to create the file even though the file is opened
`O_RDONLY`.

This fix sets write intent for the file if `O_CREATE` is passed in which fixes
the problem for all the VFS cache modes.

It also extends the exhaustive open flags testing to `--vfs-cache-mode writes`
as well as `--vfs-cache-mode full` which would have caught this problem.

591fc3609a vfs: fix deadlock caused by cache cleaner and upload finishing
Before this patch a deadlock could occur if the cache cleaner was
running when an object upload finished.

This fixes the problem by delaying marking the object as clean until
we have notified the VFS layer. This means that the cache cleaner
won't consider the object until **after** the VFS layer has been
notified, thus avoiding the deadlock.

652d3cdee4 vfs: windows: fix slow opening of exe files by not truncating files when not necessary
Before this change we truncated files in the backing store regardless
of whether we needed to or not.

After, we check to see if the file is the right size and don't
truncate if it is.

Apparently Windows Defender likes to check executables each time they
are modified, and truncating a file to its existing size is enough to
trigger the Windows Defender scan. This was causing a big slowdown for
operations which opened and closed the file a lot, such as looking at
properties on an executable.

2a817e21cb vfs: fix excess CPU used by VFS cache cleaner looping
Before this change the VFS cache cleaner would loop indefinitely while
the cache was above quota. This used up all the CPU.

This fix prevents the cache cleaner from looping. It will be kicked on
ENOSPACE and run in its scheduled time otherwise so this should be
sufficient.

5605e34f7b mount: fix --devname and fusermount: unknown option 'fsname' when mounting via rc
In this commit

f4c40bf79d mount: add --devname to set the device name sent to FUSE for mount display

The --devname parameter was added. However it was soon noticed that
attempting to mount via the rc gave this error:

    mount helper error: fusermount: unknown option 'fsname'
    mount FAILED: fusermount: exit status 1

This was because the DeviceName (and VolumeName) parameter was never
being initialised when the mount was called via the rc.

The fix for this was to refactor the rc interface so it called the
same Mount method as the command line mount which initialised the
DeviceName and VolumeName parameters properly.

This also fixes the cmd/mount tests which were breaking in the same
way but since they aren't normally run on the CI we didn't notice.

🧪 fstest: fix time tests on Windows and add convenience methods to check local and remote fs with precision
Previously only the fs being checked on gets passed to
GetModifyWindow(). However, in most tests, the test files are
generated in the local fs and transferred to the remote fs. So the
local fs time precision has to be taken into account.

This meant that on Windows the time tests failed because the
local fs has a time precision of 100ns. Checking remote items uploaded
from local fs on Windows also requires a modify window of 100ns.
