For some files the Windows Volume Shadow Service (VSS) advertises the
file size as X in the directory listing but returns a different number
Y on stat-ing the file. If the file is opened and read there are Y
bytes available for reading.
Existing copy tools copy Y bytes rather than X so for consistency
rclone should do the same.
This fixes the problem by stat-ing the file immediately before opening
it. This will also reduce the unnecessary occurrence of "can't copy -
source file is being updated" errors; if the file has finished
changing by the time we come to copy it then we now can copy it
successfully.

Streaming uploads are used by rclone rcat and rclone mount
--vfs-cache-mode off.
After the multipart chunker refactor the multipart chunked streaming
upload was accidentally mixing the first and the second parts up which
was causing corrupted uploads.
This was caused by a simple off by one error in the refactoring where
we went from 1 based part number counting to 0 based part number
counting.
Fixing this revealed that the metadata wasn't being re-read for the
copied object either.
This fixes both of those issues and adds an integration tests so it
won't happen again.

After the multipart chunker refactor the multipart chunked server side
copy was accidentally sending one part too many. The last part was 0
length which was rejected by b2.
This was caused by a simple off by one error in the refactoring where
we went from 1 based part number counting to 0 based part number
counting.
Fixing this revealed that the metadata wasn't being re-read for the
copied object either.

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
Before this change, attempting to server side copy a google form would
give this error
No export formats found for "application/vnd.google-apps.form"
Adding this flag allows the form to be server side copied but not
downloaded.
Fixes#6302
In v1.63 memory usage in the b2 backend was limited to `--transfers` *
`--b2-chunk-size`
However in v1.64 this was raised to `--transfers` * `--b2-chunk-size`
* `--b2-upload-concurrency`.
The default value for this was accidently set quite high at 16 which
means by default rclone could use up to 6.4GB of memory!
The new default sets a more reasonable (but still high) max memory of 1.6GB.
Before this change, the lock was held while the upload URL was being
fetched from the server.
This meant that any other threads were blocked from getting upload
URLs unecessarily.
It also increased the potential for deadlock.
Most useful is the addition of the file created timestamp, but also a timestamp for
when the file was uploaded.
Currently supporting a rather minimalistic set of metadata items, see PR #6359 for
some thoughts about possible extensions.

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.

Before this change the b2 backend listed all the buckets to turn a
single bucket name into an ID.
However in July 26, 2018 a parameter was added to the list buckets API
to make listing all the buckets unecessary.
This code sets the bucketName parameter so that only the results for
the desired bucket are returned.
The improved upload logic is active by default in uplink v1.12.0, so the
`testuplink.WithConcurrentSegmentUploadsDefaultConfig(ctx)` is not
required anymore.

Before this change uploaded files could return the error "replication
in progress".
This error is harmless though and means the Close should be retried
which is what this patch does.
In this commit we discovered a problem with objects being uploaded to
the incorrect object name. It added an integration test for the
problem.
65b2e378e0 drive: fix incorrect remote after Update on object
This test was tripped by the hdfs backend and this patch fixes the
problem.
Sometimes opendrive reports "403 Folder is already deleted" on
directories which should exist.
This might be a bug in opendrive or in rclone however we work-around
here sufficient to get the tests passing.
ChangeNotify has been broken on the compress backend for a long time!
Before this change it was wrapping the file names received rather than
unwrapping them to discover the original names.
It is likely ChangeNotify was working adequately though for users as
the VFS just uses the directories rather than the file names.
