This allows us to better implement alternative drivers
for devices, such as for device sharing servers or
talking to CoreMini processors within the same device.
Because there is now more than one "product name" per device
type, we have a concept of a "generic product name" which
singularly maps onto a device type.
This change comes with a few small breaking changes within
the C++ API:
DeviceType::GetDeviceTypeString has been renamed to
DeviceType::GetGenericProductName to denote that
the returned value is not device specific and
device->getProductName() is preferable.
The member function DeviceType::toString has been renamed
to DeviceType::getGenericProductName for the same reason.
The DeviceType std::ostream& operator<< has been removed
to avoid accidental use of the generic product name.
