As a way to make it more difficult to introduce bugs into the ARC, and to
make it easier to diagnose issues when bugs do creep in, it would be
beneficial to change the type of the arc_state_t's arcs_size field to be
a refcount_t instead of a uint64_t. This would allow us to make stricter
checks when incrementing and decrementing the value with debugging enabled,
but still fallback to simple, fast atomic operations when debugging is
disabled.
