local: make --local-no-updated provide a consistent view of the objects
Before this change the --local-no-updated flag would not error if the
files changed in size during the transfer. The file could still be
read beyond the size advertised though which caused problems with
certain backends.
After this change we attempt to provide a consistent view of the file
once it has been opened.
Once the file has had stat() called on it for the first time we
- Only transfer the size that stat gave
- Only checksum the size that stat gave
- Don't update the stat info for the file
This means that files that are extending can be transferred - rclone
will transfer the length it saw the first time it listed the file.
drive: Allow the use of --drive-impersonate with the root_folder_id "appDataFolder"

5c5ad6220 drive: fix --drive-impersonate with cached root_folder_id
We disabled the use of root_folder_id with --drive-impersonate to fix
a problem with a cached root_folder_id giving the wrong results.
This, alas, broke one users setup with a root_folder_id of
appDataFolder. Since this is identifiable and definitely couldn't have
been cached, we can safely skip this check in this case.
