Michael Eischer 6877e7edbb repository: Rename LoadAndDecrypt to LoadUnpacked
The method is the complement for SaveUnpacked and not for
SaveAndEncrypt. The latter assembles blobs into pack files.

When storing a blob fails, this is a fatal error which must not be
retried.

Michael Eischer c4a2bfcb39 repository: Add StreamPacks function
The function supports efficiently loading a specified list of blobs from
a single pack in a streaming fashion. That is there's no need for
temporary files independent of the pack size.

Michael Eischer 9aa2eff384 Add plumbing to calculate backend specific file hash for upload
This enables the backends to request the calculation of a
backend-specific hash. For the currently supported backends this will
always be MD5. The hash calculation happens as early as possible, for
pack files this is during assembly of the pack file. That way the hash
would even capture corruptions of the temporary pack file on disk.

Ryan Hitchman 77bf148460 backup: add --dry-run/-n flag to show what would happen.
This can be used to check how large a backup is or validate exclusions.
It does not actually write any data to the underlying backend. This is
implemented as a simple overlay backend that accepts writes without
forwarding them, passes through reads, and generally does the minimal
necessary to pretend that progress is actually happening.

Fixes #1542

Example usage:

$ restic -vv --dry-run . | grep add

Michael Eischer e638b46a13 Embed context into ReaderAt
The io.Reader interface does not support contexts, such that it is
necessary to embed the context into the backendReaderAt struct. This has
the problem that a reader might suddenly stop working when it's
contained context is canceled. However, this is now problem here as the
reader instances never escape the calling function.

Michael Eischer a449450021 init: pass proper context to master key generation
This is no change in behavior as a canceled context did later on cause
the config file creation to fail. Therefore this change just lets the
repository initialization fail a bit earlier.

to be, but the test is cleaner and more exhaustive. sortCachedPacksFirst

Alexander Weiss 91906911b0 Fix non-intuitive repository behavior
- The SaveBlob method now checks for duplicates.
- Moves handling of pending blobs to MasterIndex.
  -> also cleans up pending index entries when they are saved in the index
  -> when using SaveBlob no need to care about index any longer
- Always check for full index and save it when storing packs.
  -> removes the need of an index uploader
  -> also removes the verbose "uploaded intermediate index" messages
- The Flush method now also saves the index
- Fix race condition when checking and saving full/non-finalized indexes
