Before this change serving bucket based objects
`[remote:bucket]/path/to/object` would fail with 404 not found.
This was because the leading `/` in `/path/to/object` was being passed
to NewObject.
When sorting fs.DirEntries we sort by DirEntry type and
when synchronizing files let the directories be before objects,
so when the destintation fs doesn't support duplicate names,
we will only lose duplicated object instead of whole directory.
The enables synchronisation to work with a file and a directory of the same name
which is reasonably common on bucket based remotes.
Before this change, when using rclone copy or move with --backup-dir
and the source was a single file, rclone would fail to use the backup
directory.
This change looks up the backup directory in the Fs cache and uses it
as appropriate.
This affects any commands which call operations.MoveFile or
operations.CopyFile which includes rclone move/moveto/copy/copyto
where the source is a single file.
Fixes#3219
Before this change we calculated the checksum which is potentially
time consuming and then ignored the result. After the change we don't
calculate the checksum if we are about to ignore it.
Tests have been randomly failing with messages like
listen tcp 127.0.0.1:51778: bind: address already in use
Rework all the test servers so they choose a random free port on
startup and use that for the tests to avoid.
In c5ac96e9e7 we made --files-from only read the objects specified and
don't scan directories.
This caused problems with Google drive (very very slow) and B2
(excessive API consumption) so it was decided to make the old
behaviour (traversing the directories) the default with --files-from
and use the existing --no-traverse flag (which has exactly the right
semantics) to enable the new non scanning behaviour.

Before the fix we were only de-duping the ListR batches.
Afterwards we dedupe everything.
This will have the consequence that rclone uses more memory as it will
build a map of all the directory names, not just the names in a given
directory.
This dramatically increases the speed (7x in my tests) of the de-dupe
as google drive supports ListR directly and dedupe did not work with
`--fast-list`.
Fixes#2902
This will increase speed for backends which support ListR and will not
have the memory overhead of using --fast-list.
It also means that errors are queued until the end so as much of the
remote will be listed as possible before returning an error.
Commands affected are:
- lsf
- ls
- lsl
- lsjson
- lsd
- md5sum/sha1sum/hashsum
- size
- delete
- cat
- settier
It otherwise has the nearly the same interface as walk.Walk which it
will fall back to if it can't use ListR.
Using walk.ListR will speed up file system operations by default and
use much less memory and start immediately compared to if --fast-list
had been supplied.
