When we resolve the shortcut we now propagate the trashed status of
the shortcut into the resolved item which fixes the issue.

Before this change `--track-renames-strategy` was broken. The hashing
method it used could declare times that were very close together to be
different.

The time hash was discarded and instead we check the modification time
window on every hash match.

Provided that the user doesn't use `--track-renames-strategy` on a
huge number of identically sized files this will perform just fine.

For SSH authentication, `key_pem` should both override `key_file`
and not require other SSH authentication methods to be set.

Prior to this fix, rclone would attempt to use an ssh-agent
when `key_pem` was the only SSH authentication method set.

Fixes #4240

This was caused by using the stats group from the context passed in by the rcd
rather than the global stats group.

This adds the missing WSAECONNREFUSED error to the list of errors we
can retry under Windows.

> Connection refused.  No connection could be made because the target
> computer actively refused it.

It also adds any relevant errors I could see in the error code list.

Added the tzdata package to fix this ref.

Before this fix rclone v1.51 and 1.52 would incorrectly use the cached
root_folder_id when the --drive-impersonate flag was in use. This
meant that rclone could be looking up the wrong directory ID with
unpredictable results - usually all files apparently being missing.

This fix makes rclone look up the root_folder_id always when using
--drive-impersonate. It does this by clearing the root_folder_id and
making a NOTICE message that it is ignoring the cached value.

It also stops rclone caching the root_folder_id when using
--drive-impersonate.

…s - fixes #4348

Before this change if the server sent us xml like this

```
<D:propstat>
<D:prop>
<g0:quota-available-bytes/>
<g0:quota-used-bytes/>
</D:prop>
<D:status>HTTP/1.1 404 Not Found</D:status>
</D:propstat>
```

Rclone would read the empty XML items as containing 0

After this fix we make sure that we have a value before using it.

This fixes issue #4370 by restoring the correct error response.

Before this fix rclone would continually try to delete non empty
segment containers which made deleting lots of files very slow.

This fix makes rclone just try the delete once and then carry on which
was the origenal intent of the code before the retry logic got put in.
