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.

prune: Abort repacking when a pack contains a wrong blob
...
If a blob in a pack file can be decrypted successfully but contains data
that results in a different hash than stated in the header pack, then
abort repacking. As both the pack header and the blob are
cryptographically verified this either means than a malicious entity
tampered with the backup or indicates hardware problems on the client.
prune should fail with an error in both cases.

Parallel index benchmarks + benchmark optimizations
...
createRandomIndex was using the global RNG, which locks on every call
It was also using twice as many random numbers as necessary and doing
a float division in every iteration of the inner loop.
BenchmarkDecodeIndex was using too short an input, especially for a
parallel version. (It may now be using one that is a bit large.)

don't save duplicate packIDs when using internal/repository/Index.Store

save packIDs and duplicates separately
...
A side remark to the definition of Index.blob:
Another possibility would have been to use:
blob map[restic.BlobHandle]*indexEntry
This would have led to the following sizes:
key: 32 + 1 = 33 bytes
value: 8 bytes
indexEntry: 8 + 4 + 4 = 16 bytes
each packID: 32 bytes
To save N index entries, we would therefore have needed:
N * OF * (33 + 8) bytes + N * 16 + N * 32 bytes / BP = N * 82 bytes
More precicely, using a pointer instead of a direct entry is the better memory choice if:
OF * 8 bytes + entrysize < OF * entrysize <=> entrysize > 8 bytes * OF/(OF-1)
Under the assumption of OF=1.5, this means using pointers would have been the better choice
if sizeof(indexEntry) > 24 bytes.

- 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

Allow specifying user and host when adding keys

The username and hostname for new keys can be specified with the new
--user and --host flags, respectively. The flags are used only by the
`key add` command and are otherwise ignored.
This allows adding keys with for a desired user and host without having
to run restic as that particular user on that particular host, making
automated key management easier.

repository: Don't sort one element pack lists
...
When loading a blob, restic first looks up pack files containing the
blob. To avoid unnecessary work an already cached pack file is preferred.
However, if there is only a single pack file to choose from (which is
the normal case) sorting the one-element list won't change anything.
Therefore avoid the unnecessary cache check in that case.
