67e2ba0d40 repository: Lock requires *repository.Repository
This allows the Lock function to access the backend, even once the
Backend method is removed from the interface.

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.

1d6d3656b0 repository: move backend.LoadAll to repository.LoadRaw
LoadRaw also includes improved context cancellation handling similar to the
implementation in repository.LoadUnpacked.

The removed cache backend test will be added again later on.

20d8eed400 repository: streamPack: separate requests for gap larger than 1MB
With most cloud providers, traffic is much more expensive than API
calls. Thus slightly bias streamPack towards a bit more API calls in
exchange for slightly less traffic.

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.

defd7ae729 prune/repair index: reset in-memory index after command
The current in-memory index becomes stale after prune or repair index
have run. Thus, just drop the in-memory index altogether once these
commands have finished.

310db03c0e repair index: improve log output if index cannot be deleted
The operation will always fail with an error if an index cannot be
