Every RemoteError message and HttpStorage's Debug output held the URL as
given, with any user:password@ and the query string — for a presigned
S3/GCS/Azure URL, its signature or token. An application logging the
error leaked the credential.
- New clawhdf5_remote::redact_url: no userinfo, no fragment, query values
replaced by REDACTED (plain key names kept).
- HttpStorage formats every message with the redacted URL, and scrubs the
URL's secret parts from errors of the HTTP client (whose texts can echo
the URI); Debug shows the redacted URL. storage_for_url's and the object
store URL errors are redacted too. HttpStorage::url() still returns the
URL as given, documented as not for logging.
- h5rs prints FILE arguments that are URLs redacted: in errors and in
dump/stat/check/diff output.
- The test server can force a status and send a wrong Content-Range.
Tests: 404, 403 (at open and on a read), wrong Content-Range (at open and
on a read), no range support, encoded body, ETag change, timeout,
connection closed and bad scheme errors, Display and Debug, contain none
of the secrets; h5rs likewise for every subcommand.
