Michael Eischer 51b7e3119b mem: calculate md5 content hash for uploads
The mem backend is primarily used for testing. This ensures that the
upload hash calculation gets appropriate test coverage.

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.

Michael Eischer c73316a111 backends: add sanity check for the uploaded file size
Bugs in the error handling while uploading a file to the backend could
cause incomplete files, e.g. https://github.com/golang/go/issues/42400
which could affect the local backend.

Proactively add sanity checks which will treat an upload as failed if
the reported upload size does not match the actual file size.

Alexander Neumann 99f7fd74e3 backend: Improve Save()
As mentioned in issue [#1560](https://github.com/restic/restic/pull/1560#issuecomment-364689346)
this changes the signature for `backend.Save()`. It now takes a
parameter of interface type `RewindReader`, so that the backend
implementations or our `RetryBackend` middleware can reset the reader to
the beginning and then retry an upload operation.

The `RewindReader` interface also provides a `Length()` method, which is
used in the backend to get the size of the data to be saved. This
removes several ugly hacks we had to do to pull the size back out of the
`io.Reader` passed to `Save()` before. In the `s3` and `rest` backend
this is actively used.
