[PATCH v5 2/5] fcntl: rename rw_hint_* to rw_lifetime_hint_*

F_GET/SET_RW_HINT fcntl handlers query/set write life hints.
Rename the handlers/helpers to be explicit that write life hints are
being handled.

This is in preparation to introduce a new interface that supports more
than one type of write hint.
