refactor(io): make rstream use a linear buffer

If you like it you shouldn't put a ring on it.

This is what _every_ consumer of RStream used anyway, either by calling
rbuffer_reset, or rbuffer_consumed_compact (same as rbuffer_reset
without needing a scratch buffer), or by consuming everything in
each stream_read_cb call directly.
