Instead of showing the "attached" state with the VH{aA} events, we show
when the call to nosv_attach() and nosv_detach() take place. The old
VH{aA} events are now ignored. Bumps the nOS-V model version to 1.1.0.
Until now, emulation models were always being registered via probe(),
which causes the emulator to initialize all the channels. To reduce the
overhead, the channels were not connected or registered in the bay
until the first event of that model was received. This delayed connect
was causing issues in muxes where the newly connected model required
refreshing the touched channels. Which in turn was causing unexpected
PRV events.
By determining which models we need to enable, we can remove the delayed
connect mechanism and just enable those models at initialization time,
and connect the channels.
