      When we read a device from the file, we want to be able to add
      it to the studio and the sequencer immediately.  But to do so,
      we (now) need to be able to provide a base instrument number for
      the device.  We can make up a plausible one (we know what type
      of device it is, and that's the main determining factor) but we
      can't know for sure whether it's the same one as used in the
      file until we have continued and read the first instrument
      definition in the device.

      Device and instrument numbers in the file have always been
      problematic in other ways as well.  Rosegarden actually never
      used the device numbers loaded from the file (we always made up
      a new device number for each device as we read it) and it was
      theoretically possible for the instrument definitions to end up
      attached to different devices from the ones they were hung onto
      in the file (because of the way we sometimes re-used instruments
      that already existed in the studio).

      Our new approach is to assume that we will _never_ believe the
      device or instrument numbers found in the file, except for the
      purposes of resolving internal references within the file.  (The
      main examples of these are track -> instrument mappings outside
      of the studio definition, and metronome -> instrument mappings
      within a device.)  Instead, we assign a new device ID to each
      device based on its type and the available spare IDs; we assign
      a new instrument ID to each instrument based on the device type;
      and we maintain a map from "file" to "actual" instrument IDs as
      we go along, using this to resolve the track -> instrument and
      metronome -> instrument references at the end of the file (see
      the endElement method for rosegarden-data element).
    */

    /*
      This function is first called for any given instrument when
      first reading that instrument's definition in the context of a
      device definition.  So we know that if the instrument is not in
      the map already, then m_deviceInstrumentBase must contain a
      valid instrument base ID that was set when we added the device.

      To map from the number we just read, we subtract
      m_deviceReadInstrumentBase (if it exists; otherwise we set it as
      this is the first instrument for this device) and add
      m_deviceInstrumentBase.
