SDK v2 conversion
Changes
- `--s3-sts-endpoint` is no longer supported
- `--s3-use-unsigned-payload` to control use of trailer checksums (needed for non AWS)
When getting an object by specifying a versionId in the request, if the
specified version is a delete marker, it returns 405 (Method Not Allowed),
instead of 404 (Not Found) which would be returned without a versionId. See
https://docs.aws.amazon.com/AmazonS3/latest/userguide/DeleteMarker.html
Before this change, we were only looking for 404 (and not 405) to determine
whether the object exists. This meant that in some circumstances (ex. when
Versioning is enabled for the bucket and we have a non-null X-Amz-Version-Id), we
deemed the object to exist when we should not have.
After this change, 405 (Method Not Allowed) is treated the same as 404 (Not
Found) for the purposes of headObject.

`remote` has been converted ToStandardPath a few lines above, so `directory`
needs to be converted the same way in order to be compared properly. This was
spotted on `TestBisyncRemoteRemote/extended_filenames` for
`TestS3,directory_markers:` and `TestGoogleCloudStorage,directory_markers:`
which tripped over a directory name containing a Line Feed symbol.
GCS gives NotImplemented errors for multi-part server side copies. The
threshold for these is currently set just below 5G so any files bigger
than 5G that rclone attempts to server side copy will fail.
This patch works around the problem by adding a quirk for GCS raising
--s3-copy-cutoff to the maximum. This means that rclone will never use
multi-part copies for files in GCS. This includes files bigger than
5GB which (according to AWS documentation) must be copied with
multi-part copy. However this seems to work with GCS.

Fixes#7062
Before this change if you tried to create a bucket that already
existed, but someone else owned then rclone did not return an error.
This now will return an error on providers that return the
AlreadyOwnedByYou error code or no error on bucket creation of an
existing bucket owned by you.
This introduces a new provider quirk and this has been set or cleared
for as many providers as can be tested. This can be overridden by the
--s3-use-already-exists flag.
Fixes#7351
In this commit:
5f938fb9ed s3: fix "Entry doesn't belong in directory" errors when using directory markers
We checked that the remote has the prefix and then changed the remote
before removing the prefix. This sometimes causes:
panic: runtime error: slice bounds out of range [56:55]
The fix is to do the modification of the remote after removing the
prefix.
See: https://forum.rclone.org/t/cryptcheck-panic-runtime-error-slice-bounds-out-of-range/41977
Before this change the concurrency used for an upload was rather
inconsistent.
- if size below `--backend-upload-cutoff` (default 200M) do single part upload.
- if size below `--multi-thread-cutoff` (default 256M) or using streaming
uploads (eg `rclone rcat) do multipart upload using
`--backend-upload-concurrency` to set the concurrency used by the uploader.
- otherwise do multipart upload using `--multi-thread-streams` to set the
concurrency.
This change makes the default for the concurrency used be the
`--backend-upload-concurrency`. If `--multi-thread-streams` is set and larger
than the `--backend-upload-concurrency` then that will be used instead.
This means that if the user sets `--backend-upload-concurrency` then it will be
obeyed for all multipart/multi-thread transfers and the user can override them
all with `--multi-thread-streams`.
See: #7056
This makes the memory controls of the s3 backend inoperative and
replaced with the global ones.
--s3-memory-pool-flush-time
--s3-memory-pool-use-mmap
By using the buffered reader this fixes excessive memory use when
uploading large files as it will share memory pages between all
readers.
Fixes#7141
