Changed the reports in the GenericHID device demos to control the board LEDs, to reduce user confusion over the callback routines.
Fixed swapped TWI_ADDRESS_READ and TWI_ADDRESS_WRITE values.
Fixed TWI_ReadPacket() not releasing the TWI bus on read completion.
Added new HCI states to properly initialize the bluetooth dongle and retrieve the local BDADDR.
Factored out Bluetooth state information into a new state structure for easy reference in the user application.
Added new StackInitialized() Bluetooth stack callback function.
Add Link Key Request event processing so that paired devices always re-authenticate until appropriate link key store/retrieve callbacks are implemented.
Add Bluetooth connection request/complete/disconnection callbacks.
Remove debugging from HCI layer, as it is now operational -- add guards to ACL debug statements to reduce logging chattyness so that the overall command sequences can be observed and debugged.
Clean up RelayBoard project code.
Make AVRISP project clear the XMEGA target's reset register twice; this does not appear to take affect properly the first time under some circumstances.
Remove VBUS events - not needed as the library takes care of VBUS detection and feedback on supported AVRs via the USB_Device_Connected and USB_Device_Disconnected events.
Fixed incorrect Host state assignment in the incomplete BluetoothHost demo.
Added new Endpoint_ClearStatusStage() convenience function to assist with the status stages of control transfers.
Removed vague USB_IsConnected global - test USB_DeviceState or USB_HostState explicitly to gain previous functionality.
Removed USB_IsSuspended global - test USB_DeviceState against DEVICE_STATE_Suspended instead.
Fixed possible enumeration errors from spinloops which may fail to exit if the USB connection is severed before the exit condition becomes true.
Seperated out Lib components of the incomplete BluetoothHost demo application out into a seperate Lib subfolder.
Changed F_CLOCK entries in project makefiles to alias to F_CPU by default, as this is the most common case.
