Remove redundant type information for bitfield elements, other than the signed/unsignedness of the element.

Change type of USB_SelectedPipe and USB_SelectedEndpoint for the AVR32 UC3 architecture to uint32_t to reduce the compiled code size.

Removed SerialStream module, rolled functionality into the base USART Serial peripheral driver instead through the new Serial_CreateStream() and Serial_CreateBlockingStream() methods.

Renamed the Serial byte send/receive functions to remain consistent with the CDC driver's byte functions.

Altered the serial byte receive function to make it non-blocking.

Changed over www.fourwalledcubicle.com links to the new www.lufa-lib.org redirect domain, including the new aliased links for LUFA-related pages such as the various download/source control mirrors and support lists.

Update all demos, projects and bootloaders to indent all function parameters, one per line, for better readability.

Add missing const qualifiers to the demos.

Rename Bluetooth stack function parameters to clearly indicate what sort of Bluetooth channel (ACL, RFCOMM) is required for each parameter, to make the code easier to read.

Add a new RFCOMM_ChannelSignalsReceived() Bluetooth stack callback from the RFCOMM layer for when the remote device sends new terminal control signals.

Fix RFCOMM_SendData() not aborting correctly when the requested RFCOMM channel is not found.

Move out RFCOMM channel structure init code to a seperate routine, to save on compiled code space and to prevent copy-paste errors.

Add RFCOMM service routine, to send pending configuration requests on RFCOMM channels. Add in RFCOMM channel config flags, to determine which configuration commands have been sent and received.

Add a new RFCOMM_SendChannelSignals() function to transmit a change in V24 terminal handshake lines to the receiving device.

Prevent SABM packets sent to the control DLCI in the RFCOMM layer from creating a new channel entry, as the control DLCI does not have connection data associated with it.

Fix up MSC control packet handling so that received responses can be acknowledged correctly, so that the RFCOMM layer can record when the receiving device has ACKed a sent change in V24 terminal handshake lines.

Split RFCOMM channel signals into Remote and Local pairs. Use memcpy() to copy over data from the command parameters to the RFCOMM response parameters.

Ensure that only the valid parameter bytes are sent back in response to MSC commands.

Add TEST RFCOMM command handler. Remove the RFCOMM channel UseUIFrame element, as the Bluetooth adaptions to RFCOMM only allow UIH frames to be used.

Rename RFCOMM_GetFrameDataLength() to RFCOMM_GetVariableFieldValue() as it is multi-purpose, and modify it to move the buffer pointer itself rather than relying on the caller.

Make RFCOMM_GetChannelData() return NULL if the required channel DLCI is found, but the channel is closed.

Add modem signals (BREAK, DCD, etc.) to the channel state array, and add in a handler for the Modem Status RFCOMM control command.

Add missing BT_* prefix to the Bluetooth stack's channel state enum values.

Split out the RFCOMM Control Channel command processing code into a seperate set of files for clarity.
