New HID report item macros (with HID_RI_ prefix) to allow for easy creation and editing of HID report descriptors.

Changed over all project and demo HID report descriptors to use the new HID report item macros.

Moved the HIDParser.c source file to the LUFA/Drivers/USB/Class/Common/ directory from the LUFA/Drivers/USB/Class/Host/.

Added new high level TWI packet read/write commands, altered behaviour of the TWI_StartTransmission() function.

Spell check source code files.

Call USB_USBTask() in the Endpoint stream functions between packets if INTERRUPT_CONTROL_ENDPOINT is not set. Remove calls to USB_USBTask in the Mass Storage class driver stream read/write continuation checks, since this is now done inside the stream function.

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).

The FAST_STREAM_TRANSFERS compile time option has been removed due to lack of use and low cost/benefit ratio.

Add GCC_FORCE_POINTER_ACCESS() macro use to the RingBuffer library header, to attempt to force GCC into producing more efficient code for manipulating the buffers.

Update Doxygen documentation configuration file for the main project documentation to the latest version. Add missing data structure documentation briefs.

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

Much more efficient algorithm for the Endpoint/Pipe configuration routine of unordered endpoints/pipes - only reconfigure the endpoints and pipes above the newly configured endpoint/pipe, and don't cache existing endpoint/pipe configuration before use to save SRAM.

Re-add in old Endpoint/Pipe workaround for unordered pipes - add new ORDERED_EP_CONFIG compile time option to override the workaround and use the previous behaviour that imposes correct Endpoint/Pipe ordering but produces smaller compiled code.

Fixed incorrect definition of the HID_KEYBOARD_SC_D constant in the HID class driver (thanks to Opendous Inc.).

Add extra comments to the ISPTarget.c source file in the AVRISP-MKII clone project.

Refactored Host mode Class Driver *_Host_ConfigurePipes() routines to be more space efficient when compiled.

Added new *_ENUMERROR_PipeConfigurationFailed error codes for the *_Host_ConfigurePipes() routines.

Remove internal USB_Device_NibbleToASCII() function in favour of manually inlined code to prevent compilation errors in -O0 optimisation level.

Renamed the EVENT_USB_Device_UnhandledControlRequest() event to EVENT_USB_Device_ControlRequest() as it is now fired before the library request handlers, not afterwards.

Fixed USBtoSerial and XPLAINBridge demos discarding data from the PC if the send buffer becomes full.

Fixed MIDI class driver send routines silently discarding packets if the endpoint or pipe is busy (thanks to Robin Green).

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).

Add logical grouping of related #define values for better Doxygen documentation.

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.

Added new NO_CLASS_DRIVER_AUTOFLUSH compile time option to disable automatic flushing of interfaces when the USB management tasks for each driver is called.

The MIDI class drivers now automatically flushes the MIDI interface when the MIDI class driver's USBTask() function is called.

Changed AudioInput and AudioOutput demos to reload the next sample via an interrupt rather than polling the sample timer.

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.

Better algorithm to extract and convert the internal device serial number into a string descriptor (if present).

Fix incorrect warning text when an unsuitable F_CLOCK value is given.

Renamed ENDPOINT_DOUBLEBANK_SUPPORTED() to ENDPOINT_BANKS_SUPPORTED() and changed it to return the maximum number of supported banks for the given endpoint.

Fixed MIDI_Host_Flush() not aborting early when the specified MIDI host interface was not configured.

Small documentation improvements to explicitly reference tokens in Doxygen, to ensure that they are converted to cross-reference links in the output files.

Moved the USB device selection logic for ENDPOINT_TOTAL_ENDPOINTS further up in Endpoint.h to where the endpoint bank capabilities are determined, to reduce the total number of device-specific logic.

Change USB_Host_WaitMS() to test and disable the HSOFI interrupt before resuming the bus, so that it does not fire before the delay loop has run.

Add missing const qualifier to the parameter of USB_Host_ClearPipeStall().
