Rename new Audio class driver functions, callbacks and events to ensure that they contain the USB mode (Device or Host) in the function names.

Add macro guards to the templated C files to prevent compile errors if they are mistakenly compiled as regular source files in a LUFA project.

Rename Audio Host Class driver internal descriptor matching routines to be in line with the rest of the class driver function names.

Ensure that only the requested Audio class pipes are mapped to endpoints within the device for a specific Audio Host Class driver instance.

Fix const-correctness of the Audio Host Class driver.

Correct errors in the existing Audio demo description files due to the new demo features (variable sampling rate vs. a fixed sampling rate).

Fix errors in the new Audio Host mode Class Driver, which would have prevented data from being sent or received properly by the device.

Add microphone/square wave generation compile time switch to the Low Level AudioOutput Host demo.

Pipe_BoundEndpointNumber() has been renamed to Pipe_GetBoundEndpointAddress(), and now returns the correct endpoint direction as part of the endpoint address.

Add Audio_GetSetEndpointProperty() function to the Host mode Audio class driver.

Remove warnings in the documentation for the library class drivers about sequential pipe/endpoint allocation, as by default this is no longer as issue (unless ORDERED_EP_CONFIG is specified).

Added new EVENT_Audio_StreamStartStopChange() event to the Audio Device Class driver to detect stream start/stop events.

Partial commit: Rename USBFOO LED driver to fix capitalisation of file name, which will cause issues on *nix systems.

Partial commit: Rename USBFOO LED driver to fix capitalisation of file name, which will cause issues on *nix systems.

Update incomplete Host mode Audio demos to use the correct class driver Endpoint Sampling Frequency Control value constant.

Remove custom PIDs on the Class Driver Audio device demos and revert back to the original Audio PIDs, as the low level and class driver demo versions are now descriptor compatible once again.

Massive corrections to the project documentation and code comments, thanks to Russian translation services provided by Andrey from Microsin.ru.

Added new callback to the Audio Class driver to allow for endpoint control manipulations such as data sample rates.

Modified the Class Driver AudioInput and AudioOutput demos to support multiple sample rates.

Fixed KeyboardHost and KeyboardHostWithParser demos displaying incorrect values when numerical keys were pressed.

Fix broken LowLevel audio demo descriptors.

Minor documentation fixes.

Expand the documentation for each Bootloader to give sample usage instructions for the command line programmer utilities.

Fix typo in the HID class bootloader CLI programmer application usage instructions.

Minor documentation cleanups.

Modify the incomplete AudioInputHost demo for mono audio output.

Altered the definition of the USB_Audio_Descriptor_Format_t descriptor so that the user is now responsible for supplying the supported audio sampling rates, to allow for multiple audio interfaces with different numbers of supported rates and/or continuous sample rates.

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.

Fix incorrect project name in the Projects/ folder makefile.

Copy out the EndpointStream and PipeStream functions to each architecture, so that each architecture can optimise the stream functions according to the available hardware (such as DMA, where available).

Lower the size of the HID report endpoint from 16 bytes to 8 bytes, to allow for Low Speed USB compatibility in the KeyboardMouseMultiReport demo (thanks to Kevin Chernoff).
