record-btrace: add (reverse-)stepping support
Provide to_resume and to_wait target methods for the btrace record target
to allow reverse stepping and replay support.
Replay is limited in the sense that only stepping and source correlation
are supported. We do not record data and thus can not show variables.
Non-stop mode is not working. Do not allow record-btrace in non-stop mode.
