The v1 wire marshaler sorts fields as follows: - All extensions, sorted by field number. - All non-oneof fields, sorted by field number. - All oneof fields, in indeterminate order. We already make some steps toward supporting this ordering: The fast path encoder places extensions in sorted order at the start of the message. This commit moves oneof fields to the end of the message, makes the reflection-based encoder use this ordering when deterministic marshaling is enabled, and adds a test to catch unintentional changes to the ordering. Users SHOULD NOT depend on stability of the marshal output. It is subject to change over time. Without deterministic marshaling enabled, it is subject to change over calls to Marshal.
