upstream: Use new limits@openssh.com protocol extension to let the
client select good limits based on what the server supports. Split the
download and upload buffer sizes to allow them to be chosen independently.
In practice (and assuming upgraded sftp/sftp-server at each end), this
increases the download buffer 32->64KiB and the upload buffer
32->255KiB.
