Before this change we truncated files in the backing store regardless
of whether we needed to or not.
After, we check to see if the file is the right size and don't
truncate if it is.
Apparently Windows Defender likes to check executables each time they
are modified, and truncating a file to its existing size is enough to
trigger the Windows Defender scan. This was causing a big slowdown for
operations which opened and closed the file a lot, such as looking at
properties on an executable.

Fish is different from POSIX-based Unix shells such as bash,
and a bracketed variable references like we use for the
auto-detection echo command is not supported. The command
will return with zero exit code but produce no output on
stdout. There is a message on stderr, but we don't log it
due to the zero exit code:
fish: Variables cannot be bracketed. In fish, please use {$ShellId}.
Fixes#6552
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 patch, when an alias backend was created it would be
renamed to be canonical and in the process Shutdown would be called on
it. This was particularly noticeable with the dropbox backend which
gave this error when uploading files after the backend was Shutdown.
Failed to copy: upload failed: batcher is shutting down
This patch fixes the cache Rename code not to finalize objects if the
object that is being overwritten is the same as the existing object.

Solves link error while running rclone's wasm version. Go's `walltime1` function was renamed to `walltime`. This commit updates wasm_exec.js with the new name.
Before this change, some files were giving this error when downloaded
from Cloudflare and other providers.
ERROR corrupted on transfer: sizes differ NNN vs MMM
This is because these providers auto gzips the object when rclone
wasn't expecting it to. (AWS does not gzip objects without their being
uploaded gzipped).
This patch adds a quirk to for fix the problem and a flag to control
it. The quirk `might_gzip` is set to `true` for all providers except
AWS.

Before this fix it was impossible to stop rclone generating an
X-Amx-Acl: header which is incompatible with GCS with uniform access
control and is generally deprecated at AWS.
The API endpoint GetBucketLocation requires
top level permission.
If we do an authenticated head request to a bucket, the bucket location will be returned in the HTTP headers.
Fixes#5066
