when multi-thread downloading is enabled, rclone used
to send a write to disk after every read, resulting in a lot
of small writes to different locations of the file.
depending on the underlying filesystem or device, it can be more
efficient to send bigger writes.
Before this change the pikpak backend changed the global
--multi-thread-streams flag which wasn't desirable.
Now the machinery is in place to use the NoMultiThreading feature flag
instead.
Fixes#6915
When copying to a backend which has the PartialUploads feature flag
set and can Move files the file is copied into a temporary name first.
Once the copy is complete, the file is renamed to the real
destination.
This prevents other processes from seeing partially downloaded copies
of files being downloaded and prevents overwriting the old file until
the new one is complete.
This also adds --inplace flag that can be used to disable the partial
file copy/rename feature.

Before this patch, files or directories with unknown modtime would
appear as the current date.
When mounted some systems look at modification dates of directories to
see if they change and having them change whenever they drop out of
the directory cache is not optimal.
See #6986
When using `rclone cat` to print the contents of several files, the
user may want to inject some separator between the files, such as a
comma or a newline. This patch adds a `--separator` option to the `cat`
command to make that possible. The default value remains an empty
string, `""`, maintaining the prior behavior of `rclone cat`.
Closes#6968
On Linux systems rclone builds with cgo but uses the internal Go
resolver for DNS by default.
This update the FAQ to suggest use of GODEBUG=netdns=cgo if there are
name resolution problems on Linux/BSD (with CGO_ENABLED rebuild from
source if necessary), or try GODEBUG=netdns=go on Windows/MacOS.
See: #683
If a file has two (or more) extensions and the second (or subsequent)
extension is recognised as a valid mime type, then the suffix will go
before that extension. So `file.tar.gz` would be backed up to
`file-2019-01-01.tar.gz` whereas `file.badextension.gz` would be
backed up to `file.badextension-2019-01-01.gz`
Fixes#6892
