Before this change, the overlapping check could erroneously give this
error on case insensitive file systems:
Failed to sync: destination and parameter to --backup-dir mustn't overlap
The code was fixed and re-worked to be simpler and more reliable.

Before this change the new partial downloads code was causing symlinks
to be copied as regular files.
This was because the partial isn't named .rclonelink so the local
backend saves it as a normal file and renaming it to .rclonelink
doesn't cause it to become a symlink.
This fixes the problem by not copying .rclonelink files using the
partials mechanism but reverting to the previous --inplace behaviour.
This could potentially be fixed better in the future by changing the
local backend Move to change files to and from symlinks depending on
their name. However this was deemed too complicated for a point
release.
This also adds a test in the local backend. This test should ideally
be in operations but it isn't easy to put it there as operations knows
nothing of symlinks.
Fixes#7101

The --progress flag overrides operations.SyncPrintf in order to do its
magic on stdout without interfering with other output.
Before this change the syncFprintf routine in operations (which is
used to print all output to stdout) was taking the
operations.StdoutMutex and the printProgress function in the
--progress routine was also attempting to take the same mutex causing
a deadlock.
This patch fixes the problem by moving the locking from the
syncFprintf function to SyncPrintf. It is then up to the function
overriding this to lock the StdoutMutex. This ensures the StdoutMutex
can never cause a deadlock.
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 partially uploaded files (when --inplace is not in
effect) would be left lying around in the file system if rclone was
killed in the middle of a transfer.
This adds an exit handler to remove the file and removes it when the
file is complete.
Before this change, some parts of operations called the Open method on
objects directly, and some called NewReOpen to make an object which
can re-open itself on errors.
This adds a new function operations.Open which should be called
instead of fs.Object.Open to open a reliable stream of data and
changes all call sites to use that.
This means `rclone check --download` and `rclone cat` will re-open
files on failures.

Before this change we tested special errors for straight equality.
This works for all normal backends, but the union backend may return
wrapped errors which contain the special error types.
In particular if a pcloud backend was part of a union when attempting
to set modification times the fs.ErrorCantSetModTime return wasn't
understood because it was wrapped in a union.Error.
This fixes the problem by using errors.Is instead in all the
comparisons in operations.

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.

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
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
Before this change using operations/stat with a remote pointing to a
dir with a trailing / would return a null output rather than the
correct info.
This was because the directory was not found with a trailing slash in
the directory listing.
Fixes#6817
Before this change if both --progress and --interactive were set then
the screen display could become muddled.
This change makes --progress and --interactive use the same lock so
while rclone is asking for interactive questions, the progress will be
paused.
Fixes#6755
The recent changes to remove race conditions from --max-delete have
made these tests fail on chunker with s3 because they do copy then
delete and the deletes are being counted in the --max-delete(-size)
counts.
There were some places (e.g. deleting files) where we were using
--transfers instead of --checkers to control the concurrency when
files weren't being transferred.
These have been updated to use --checkers.
Before this change, all types of checkers showed "checking" after the
file name despite the fact that not all of them were checking.
After this change, they can show
- checking
- deleting
- hashing
- importing
- listing
- merging
- moving
- renaming

Before this change if we copied files of unknown size, then they lost
their metadata.
This was particularly noticeable using --s3-decompress.
This change adds metadata to Rcat and RcatSized and changes Copy to
pass the metadata in when it calls Rcat for an unknown sized input.
Fixes#6546
Before this change --compare-dest and --copy-dest would check to see
if the compare/copy object existed first, before seeing if the
destination object was present.
This is inefficient, because in most --copy-dest syncs the destination
will be present and the compare/copy object need never be tested.
--compare-dest syncs may also be speeded up if they are done to the
same directory repeatedly.
This fixes the problem by re-arranging the logic so if the transfer is
not needed then the compare/copy object is never tested.

strings.Title has been deprecated since Go 1.18 and an alternative has been
available since Go 1.0. The rule Title uses for word boundaries does not handle
Unicode punctuation properly. Use golang.org/x/text/cases instead.
Most of the time this will make no difference to user logs, however
the difference may be visible in JSON logs and on the rare occasions
src and dst are pointing to different file names.
