d5d28a7513 operations: fix overwrite of destination when multi-thread transfer fails
Before this change, if a multithread upload failed (let's say the
source became unavailable) rclone would finalise the file first before
aborting the transfer.

This caused the partial file to be written which would overwrite any
existing files.

This was fixed by making sure we Abort the transfer before Close-ing
it.

This updates the docs to encourage calling of Abort before Close and
updates writerAtChunkWriter to make sure that works properly.

This also reworks the tests to detect this and to make sure we upload
and download to each multi-thread capable backend (we were only
downloading before which isn't a full test).

Fixes #7071

1f9a79ef09 operations: use less memory when doing multithread uploads
For uploads which are coming from disk or going to disk or going to a
backend which doesn't need to seek except for retries this doesn't
buffer the input.

This dramatically reduces rclone's memory usage.

Fixes #7350

2db0e23584 backends: change OpenChunkWriter interface to allow backend concurrency override
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

1b5b36523b operations: fix accounting for multi-thread transfers
This stops the accounting moving in large chunks and gets it to move

fcb912a664 fs: allow setting a write buffer for multithread
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.

1f9c962183 operations: reopen downloads on error when using check --download and cat
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.

e43b5ce5e5 Remove github.com/pkg/errors and replace with std library version
This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.

This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.

2e21c58e6a fs: deglobalise the config #4685
This is done by making fs.Config private and attaching it to the
context instead.

The Config should be obtained with fs.GetConfig and fs.AddConfig
should be used to get a new mutable config that can be changed.

buf first we need to get it in place. Since this is one of those
changes that makes lots of noise, this is in a seperate commit.

bde0334bd8 operations: fix setting the timestamp on Windows for multithread copy
Before this fix we attempted to set the modification time on the file
when it was open. This works fine on Linux but not on Windows. The
test was also incorrect testing the source file rather than the
destination file.

This closes the file before setting the modification time and fixes
the tests.

Fixes #3994
