A DeleteObjects request whose Delete element names no objects was
answered with 200 and an empty DeleteResult. S3 rejects it with
MalformedXML, as the schema requires at least one Object.
Reject the empty list right after the body is parsed, next to the
1000 key limit check. Update the unit and integration tests that
expected the empty result and enable the REST test that covers it.
Fixes#2109
A bucket GET with both the uploads and uploadId query parameters was
routed to ListMultipartUploads and answered with the upload listing.
S3 rejects the combination with 400 InvalidArgument, "Conflicting query
string parameters: uploadId, uploads".
Add an error route for the combination ahead of ListMultipartUploads,
the way the object level '?uploads' request is rejected, and enable
the REST test that covers it.
Fixes#2155
A request path with an invalid percent escape, such as "/bucket/%zz",
failed url.PathUnescape in the DecodeURL middleware and the raw error
was answered with 500 InternalError. S3 rejects such a request with
400 InvalidURI.
Return InvalidURI from DecodeURL, so the s3 and admin routers answer
with it as well, and let the website handler pass the error through
instead of mapping it on its own.
Fixes#2070
