Description

RecordBatch.schema() should not return &Arc<Schema>. It should either return &Schema or Arc<Schema>.

Given that the schema could be a large nested structure and other code may want to keep references to it, Arc<Schema> is probably best.

Returning a reference to an Arc just doesn't make much sense, IMHO, and I think I was responsible for introducing this early on.
