Refuse credentials in a storage URL's endpoint or rclone remote name (closes #322)

storage_url refused only the outer URL's userinfo and unknown query
parameters. Userinfo inside the s3 endpoint= value, and rclone's
remote,param=value parameters in the remote name, were accepted and
then printed by info, remote info and snapshot create. Both are now
refused when the storage URL is parsed, without echoing the value: a
host name never contains "@", and an rclone remote name never contains
a comma. The rclone case has its own error pointing at rclone config,
since the existing credentials error names the s3.* keys.

Model: opus-5-5
