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.
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.
