634a9c162d Check cap instead of len in bloblru 
restic dump uses bloblru.Cache to keep buffers alive, but also reuses
evicted buffers. That means large buffers may be used to store small
blobs, causing the cache to think it's using less memory than it
actually does.

8d2996eaaa Replace siphash by hash/maphash 
In Go 1.17.1, maphash has become quite a bit faster than siphash, so we
can drop one third-party dependency. maphash is just an interface to the
standard Go map's hash function, which we already trust for other use
cases.

7f0aa49f45 cmd/restic: Streamline progress printing 
* PrintProgress no longer does unnecessary Sprintf calls, and performs
  fewer allocations in general
* newProgressMax's callback checks whether the terminal supports
  line updates once instead of once per call
* the callback looks up the terminal width once per call instead of
  twice (on Windows)
* the status shortening now uses the Unicode-aware version from
  internal/ui/termstatus (future-proofing)

failures.

1d3e99f475 azure: check upload using md5 content hash 
For files below 256MB this uses the md5 hash calculated while assembling
the pack file. For larger files the hash for each 100MB part is
calculated on the fly. That hash is also reused as temporary filename.
As restic only uploads encrypted data which includes among others a
random initialization vector, the file hash shouldn't be susceptible to
md5 collision attacks (even though the algorithm is broken).

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.
