a1ca5e15c4 migrations: add temporary hack for s3_layout 
The migration will be removed after the next restic release anyways.
Thus, there's no need for a clean implementation.

34d90aecf9 migrations: move logic of upgrade_repo_v2 to repository package 
The migration modifies repository internals and thus should live within
the repository package.

ab9077bc13 replace usages of backend.Remove() with repository.RemoveUnpacked() 
RemoveUnpacked will eventually block removal of all filetypes other than
snapshots. However, getting there requires a major refactor to provide
some components with privileged access.

74d90653e0 check: use ReadFull to load pack header in checkPack 
This ensures that the pack header is actually read completely.
Previously, for a truncated file it was possible to only read a part of
the header, as backend.Load(...) is not guaranteed to return as many
bytes as requested by the length parameter.

e734746f75 cache: forget cached file at most once 
This is inspired by the circuit breaker pattern used for distributed
systems. If too many requests fails, then it is better to immediately
fail new requests for a limited time to give the backend time to
recover.

By only forgetting a file in the cache at most once, we can ensure that
a broken file is only retrieved once again from the backend. If the file
stored there is broken, previously it would be cached and deleted
continuously. Now, it is retrieved only once again, all later requests
just use the cached copy and either succeed or fail immediately.

97a307df1a cache: Always use cached file if it exists 
A file is always cached whole. Thus, any out of bounds access will also
fail when directed at the backend. To handle case in which the cached
file is broken, then caller must call Cache.Forget(h) for the file in
question.

666a0b0bdb repository: streamPack: replace streaming with chunked download 
Due to the interface of streamPack, we cannot guarantee that operations
progress fast enough that the underlying connections remains open. This
introduces partial failures which massively complicate the error
handling.

Switch to a simpler approach that retrieves the pack in chunks of 32MB.
If a blob is larger than this limit, then it is downloaded separately.

To avoid multiple copies in memory, an auxiliary interface
`discardReader` is introduced that allows directly accessing the
downloaded byte slices, while still supporting the streaming used by the
`check` command.

22d0c3f8dc check: Use PackBlobIterator instead of StreamPack 
To only stream the content of a pack file once, check used StreamPack
with a custom pack load function. This combination was always brittle
and complicates using StreamPack everywhere else. Now that StreamPack
internally uses PackBlobIterator use that primitive instead, which is a
much better fit for what the check command requires.

body, immediately drain and close the body to make sure it isn't
forgotten later on.

This change in particular adds the missing `Close()` call for the

0b39940fdb walker: Remove ignoreTrees functionality 
It was only used in two places:
- stats: apparently as a minor performance optimization, which is
  unlikely to be important
- find: filtered directories would be ignored. However, this
  optimization missed that it is possible that two directories have the
  exact same content. Such directories would be incorrectly ignored too.
  Example:
```
mkdir test test/a test/b
restic backup test
restic find latest test/b
-> incorrectly does not return anything
```

Thus, remove the functionality as it's apparently too complex to use
correctly.

fe5c337ca2 repository: StreamPack delivers blobs at most once 
If an error occurred while streaming a pack file, this could result in
passing some of the blobs multiple times to the callback function. This
significantly complicates using StreamPack correctly and is unnecessary.
Retries do not change the content of a blob and thus only deliver the
same result over and over again.

indecipherable error message: `error: invalid node type ""`.

Add the filepath to the error message and state that the file type is
not supported.

a28940ea29 check: Suggest usage of restic repair packs for corrupted blobs 
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

41f70f1f4f backend/sftp: Add sftp.args option 
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
