Change the fusefs_node i_ump member name to i_fmp to better reflect
that it is a struct fusefs_mount pointer and not a struct ufsmount
pointer. There is also no need to cast it each time.

Replace the notification system with events. Events can carry a payload of
additional payload (to reduce problems with lifetime of objects) and are
delivered to one or more event sinks. This is more powerful and reduces the
complex dependencies between control mode and hooks. Events are now used for
hooks, control mode notifications and for monitors (set-hook -B).
wait-for can now wait for an event to fire (-E flag, with -F to for filter),
with -v to print the payload, as well as listing (-l) waiting clients on an
event and forcing one to wake (-w).
A few additional hooks are also now available (pane-created, pane-resized, etc)
and some of the existing ones have additional format variables available.
Change NOTHING (which means only redraw the indicator) to MOVE. And
redefine NOTHING as /actually/ nothing. Use it for commands which
actually make no change. Fixes flickering due to excessive redrawing of
indicator lines. Mostly from Michael Grant.
