g_atomic_int_get() requires a non-const pointer, however

Fix div/zero, allow switching backends
...
When switching backends, the effective sample-rate is zero.
This only affects the butler thread (the only active thread when
stopped). The actual issue here is the butler calling
"non-realtime-stop" without a backend. However fixing 0/0
generally seems appropriate.

Previously the following were treated as equal

So std::map<> PortManager::_ports and PortEngineSharedImpl:_ports

and missing calls to existing ports in cycle_start().
This mainly affected MIDI tracks with imported files, since there
is "MIDI Clock in", and imported files result in tracks
"MIDI_file-name".
