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 region specific endpoint requires CreateBucket to name that same region
in `LocationConstraint`. The gateway reported a mismatch as
`InvalidLocationConstraint`, which AWS reserves for a constraint that is
not a valid location at all, and accepted a request that omitted the
constraint entirely.
Keep `InvalidLocationConstraint` for the global `us-east-1` endpoint,
which takes no constraint, and return
`IllegalLocationConstraintException` when a region specific endpoint gets
a constraint naming another region, or none.
Fixes#2246
