greatroar 190d8e2f51 Flatten backend.LimitedReadCloser structure
This inlines the io.LimitedReader into the LimitedReadCloser body to
achieve fewer allocations. Results on linux/amd64:

Alexander Neumann d51e9d1b98 Add []byte to repo.LoadAndDecrypt and utils.LoadAll
This commit changes the signatures for repository.LoadAndDecrypt and
utils.LoadAll to allow passing in a []byte as the buffer to use. This
buffer is enlarged as needed, and returned back to the caller for
further use.

In later commits, this allows reducing allocations by reusing a buffer
for multiple calls, e.g. in a worker function.

Benoît Knecht 3c112d9cae s3: Add config option to set storage class
The `s3.storage-class` option can be passed to restic (using `-o`) to
specify the storage class to be used for S3 objects created by restic.

The storage class is passed as-is to S3, so it needs to be understood by
the API. On AWS, it can be one of `STANDARD`, `STANDARD_IA`,
`ONEZONE_IA`, `INTELLIGENT_TIERING` and `REDUCED_REDUNDANCY`. If
unspecified, the default storage class is used (`STANDARD` on AWS).

You can mix storage classes in the same bucket, and the setting isn't
stored in the restic repository, so be sure to specify it with each
command that writes to S3.

Closes #706

Alexander Neumann 3865b59716 rclone: Rework backend option parsing
This change allows passing no arguments to rclone, using `-o
rclone.args=""`. It is helpful when running rclone remotely via SSH
using a key with a forced command (via `command=` in `authorized_keys`).

Jakob Unterwurzacher dd3b9910ee sftp: persist "ssh command exited" error
If our ssh process has died, not only the next, but all subsequent
calls to clientError() should indicate the error.

restic output when the ssh process is killed with "kill -9":
