When rclone is busy doing lots of very long uploads it doesn't refresh
the token. Amazon will fail uploads if they finish when the token is
more than 1 Hour past expiry.
Fix this by keeping track of the number of uploads and refreshing the
token when the token expires if there is an upload in progress.
Amazon Drive sometimes returns errors at the end of large uploads
* 408 REQUEST_TIMEOUT
* 504 GATEWAY_TIMEOUT
* 500 Internal error
The file may have been uploaded correctly though, so, on error, wait
for up to 2 minutes for it to appear if it was fully
uploaded (configure timeout with --acd-upload-wait-time).
Issues: #601#605#606
* put the most up to date docs into the code
* generate command docs using rclone gendocs
* put command docs into own directory
* remake them into MANUAL.md
* Make move command check for overlapping remotes and refuse to run
* Do copy/delete rather than all the copies then all the deletes
* Doesn't purge the source - this was unexpected behaviour see #512 and #416
* Add -list-retries flag to test suite to control retries
This changes the semantics of `move` slightly. However it now errs on
the side of not deleting stuff.
With Keystone V3 both users and projects (a.k.a. tenants) can belong
to different domains. This change allow specifying different domains
for the user and the project.
* Factor sync/copy/move into its own file
* Make fatal errors abort the sync
* Make Copy return errors
* Make Sync/Copy/Move return the last Copy error if there was one
* Prioritise returning Fatal errors
* NoRetry errors are returned if no other types of errors
These are for remotes to signal that they have a fatal error and don't
want to continue (eg cap exceeded) or that a particular file shouldn't
be retried for some reason.
