Legacy: Drop deprecated APIs

Drop icsneoFindNeoDevices() and icsneoOpenNeoDevice() in favor of icsneoFindDevices() and icsneoOpenDevice(), respectively.

Also fixes:
- Failure to re-open a device after it has been closed with the C/legacy APIs
- NumberOfClients not being updated
- FIRE3 settings missing in icsneoGetDeviceSettingsType()
