Minor documentation cleanups.

Modify the incomplete AudioInputHost demo for mono audio output.

Remove output files from the incomplete AudioInputHost demo, and improve the logic in the ConfigDescriptor.c device configuration processing routine.

Added missing Audio class control request definitions.

Added support for the Audio class GET STATUS request so that it is correctly ACKed when sent by the host.

Fixed possible invalid program execution when in host mode if corrupt descriptor lengths are supplied by the attached device.

Minor code cleanups to add const and reformat where missing, as well as abstract out the internal device signature start address into a macro, so that it can be altered to suit particular devices within a single architecture if needed.

Add missing documentation to the USB_Device_States_t enum.

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.

Renamed all low level Endpoint_Read_*, Endpoint_Write_* and Endpoint_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Renamed all low level Pipe_Read_*, Pipe_Write_* and Pipe_Discard_* functions to use the number of bits instead of a symbolic size (Byte, Word, DWord) so that the function names are applicable and correct across all architectures.

Add new ARCH option to the makefiles to (eventually) specify the target device architecture. Update non-usb peripheral drivers to reflect future multiple architecture support.

Add static keyword to all project globals whose scope should be restricted to the same module as they are declared in.

Tighten up the HID class bootloader code slightly, document that it currently exceeds 2KB of bootloader space for all models other than the Series 2 USB AVRs.

Oops - fix up some calls to the old function names, include Serial Peripheral driver in the RNDISEthernetHost project.

Renamed the PRNT_Host_SendString(), CDC_Host_SendString() and CDC_Device_SendString() functions to *_SendData(), and added new versions of the *_SendString() routines that expect a null terminated string instead.

Added new Serial_SendData() function to the Serial driver.

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.

Altered all endpoint/pipe stream transfers so that the new BytesProcessed parameter now points to a location where the number of bytes in the transfer that have been completed can be stored (or NULL if entire transaction should be performed in one chunk).

Added new Endpoint_Null_Stream() and Pipe_Null_stream() functions.

Removed the NO_STREAM_CALLBACKS compile time option due to the new partial stream transfer feature replacing it.

Fixed errors in the incomplete Test and Measurement device demo preventing proper operation (thanks to Pavel Plotnikov).

Documentation improvements - put driver example code into its own section, fix incorrect and missing section names.

Loop in the ClassDriver MIDI device/host demos until there are no more incomming events to process. Only clear the endpoint/pipe bank in the LowLevel MIDI device/host demos when the endpoint is empty after an event read.

Fix XPLAINBridge code broken during the changes to the Rescue Clock generation in the AVRISP-MKII clone project.

Change over all low level host mode project's descriptor comparator routines to perform the descriptor casting in a temp variable to make the code clearer and easier to modify (despite being more verbose).

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.

Add descriptor class, subclass and protocol constants to the class drivers, modify all demos to use them where possible.

Move out private/internal host class driver constants to the common class driver headers, so that they can be used in the Low Level host mode demos.

Ensure all demos, projects and bootloaders use the class driver constants where possible to minimise code repetition.

All USB class drivers are now automatically included when LUFA/Drivers/USB.h is included, and no longer need to be seperately included.

All LowLevel demos changed to use the constants and types defined in the USB class drivers.

Fixed LowLevel JoystickHostWithParser demo not saving the chosen HID interface's report descriptor size.

Simplified low level Host demo configuration descriptor parser routines.

Fix low level host mode demos not correctly fetching the next endpoint when an invalid interface is discarded.

Update the pipe configuration routines in the host mode class drivers so that they use the same new code to enumerate compatible devices to increase reliability. Add support to the host mode class drivers for non-sequential (but non-overlapping with other interface) pipe numbers.

Reverted Endpoint/Pipe non-sequential configuration hack, placed restriction on the configuration order instead to ensure maximum reliability.

Altered all low level device and host mode demos to ensure that endpoints and pipes are configured in ascending order properly.

Rewrote all low level host mode demos' configuration descriptor parser code to ensure that pipes are enumerated in ascending order, and to ensure maximum compatibility with devices.

Incremented all device mode demo's device descriptor revision numbers to ensure that any descriptor changes are re-fetched on machines which have enumerated previous versions.

Add new CDC descriptor structs to the CDC class driver, so that the CDC demos can use human readable field names.

Rename prefix for Still Image Host class driver functions from "SImage_" to "SI_" to remain consistent with the rest of the driver.

Remove dfu-programmer program switches, to ensure maximum compatibility with all dfu-programmer versions.

Added the --suppress-bootloader-mem option to the makefile dfu target, to ensure that writes to the bootloader section of the AVR's flash memory are ignored (thanks to Axel Rohde).

Fixed incorrect command name for EEPROM memory programming in the makefile dfu-ee target.

Makefile whitespace fixes.

Fixed SUSPI interrupt not being cleared during device mode enumeration, causing accidental mis-fires on re-enumeration.

Fixed JTAG_DEBUG_POINT() and JTAG_DEBUG_BREAK() macros not compiling under pure C99 standards mode.

Make project makefiles correctly clean intermeditary build files from assembly and C++ sources (thanks to Daniel Czigany).

Added new PRNT_Host_BytesReceived() and PRNT_Host_ReceiveByte() functions to the Print Host Class driver.

Added new USB_Device_GetFrameNumber() and USB_Host_GetFrameNumber() functions to retrieve the current USB frame number.

Added new USB_Host_EnableSOFEvents(), USB_Host_DisableSOFEvents() and EVENT_USB_Host_StartOfFrame() for the user application handling of USB Start of Frame events while in USB Host mode.

Changed over all demos, drivers and internal functions to use the current frame number over the Start of Frame flag where possible to free up the Start of Frame flag for interrupt use in the user application.

Clarify in the project documentation files what the each of the different USB AVR device "series" comprises of.

Fixed LowLevel PrinterHost demo not sending control requests to the attached printer with the correct printer interface wIndex value.

Added new SCSI_ASENSE_NOT_READY_TO_READY_CHANGE constant to the Mass Storage class driver, to indicate when a previously not ready removable medium has now become ready for the host's use (thanks to Martin Degelsegger)
