The behavior of the new option should reflect the behavior of normal backups: when the command exit code is zero and there is no output in the stdout, emit a warning but create the snapshot. This commit fixes the integration tests and the ReadCloserCommand struct.
Return with an error containing the stderr of the given command in case it fails. No new snapshot will be created and future prune operations on the repository will remove the unreferenced data.

In order to determine whether to save a snapshot, we need to capture the exit code returned by a command. In order to provide a nice error message, we supply stderr as well.

This removes code that is only used within a backend implementation from
the backend package. The latter now only contains code that also has
external users.
For now, the guide is only shown if the blob content does not match its
hash. The main intended usage is to handle data corruption errors when
using maximum compression in restic 0.16.0
Allow setting custom arguments for the `sftp` backend, by using the
`sftp.args` option. This is similar to the approach already implemented
in the `rclone` backend, to support new arguments without requiring
future code changes for each different SSH argument.
Closes#4241
Store oversized blobs in separate pack files as the blobs is large
enough to warrant its own pack file. This simplifies the garbage
collection of such blobs and keeps the cache smaller, as oversize (tree)
blobs only have to be downloaded if they are actually used.
The old version was taken from an MPL-licensed library. This is a
cleanroom implementation. The code is shorter and it's now explicit that
only Linux ACLs are supported.
The test uses `WithTimeout` to create a context that cancels the List
operation after a given delay. Several backends internally use a derived
child context created using WithCancel.
The cancellation of a context first closes the done channel of the
context (here: the `WithTimeout` context) and _afterwards_ propagates
the cancellation to child contexts (here: the `WithCancel` context).
Therefor if the List implementation uses a child context, then it may
take a moment until that context is also cancelled. Thus give the
context cancellation a moment to propagate.
