b1266867d2 repository: wait max 1 minutes for lock removal if context is canceled
The toplevel context in restic only canceled if the user interrupts a
restic operation. If the network connection has failed this can require
waiting the full retry duration of 15 minutes which is a bad user
experience for interactive usage. Thus limit the delay to one minute in
this case.

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.

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.

cb9cbe55d9 repository: store oversized blobs in separate pack files
Store oversized blobs in separate pack files as the blobs is large
enough to warrant its own pack file. This simplifies the garbage

blobs only have to be downloaded if they are actually used.
