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.

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.

Add new MediaController project, a simple Media Playback control manipulator (Play/Pause/Next Track/Volume/etc.).

Add RNDIS Device support to the Webserver project, so that the files stored on the device can be viewed from a web-browser while the board is plugged into a host machine.

Add new RNDIS_Host_IsPacketReceived(), RNDIS_Device_ReadPacket() and RNDIS_Device_WritePacket() functions to the Device RNDIS Class Driver.

Modify RNDIS demos to suit the simplified Ethernet_Frame_Info_t structure.

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.

Add missing LEDS_ToggleLEDs() function to the LED driver for the EVK1101 board.

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.

Fixed Remote Wakeup broken on the AVRs due to the mechanism only operating when the SUSPI bit is set (thanks to Holger Steinhaus).

Remove redundant setting of UIDE in the AVR8 and AVR32 USB controller drivers.

Implemented on-demand PLL clock generation for the U4, U6 and U7 series USB AVRs when automatic PLL mode is specified.

Updated the software USART code in the XPLAIN Bridge application so that the incomming bits are sampled at their mid-point instead of starting point, to give maximum reliability (thanks to Anton).

Endpoint_ResetFIFO() renamed to Endpoint_ResetEndpoint(), to be consistent with the Pipe_ResetPipe() function name.

Fix undefined error in Pipe_UC3B.h.

Add missing migration notes.

Removed Pipe_ClearErrorFlags(), pipe error flags are now automatically cleared when Pipe_ClearError() is called.

More UC3B architecture porting.

Added TWI baud rate prescaler and bit length parameters to the TWI_Init() function (thanks to Thomas Herlinghaus).

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.

Added HID class bootloader, compatible with a modified version of the command line Teensy loader from PJRC.com.

Fixed programming errors in the AVRISP-MKII project when the programming packet is a round multiple of the endpoint bank  size under avrdude (thanks to Steffan Woltjer).

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.

Add new HID_DESCRIPTOR_VENDOR() macro, change over all projects and Device ClassDriver demos to use it.

Fix reversed byte ordering of multi-byte HID data.

Added support to the HID parser for extended USAGE items that contain the usage page as well as the usage index.

Removed the HID_IOF_NON_VOLATILE and HID_IOF_VOLATILE flags from HID INPUT items where the flag is invalid. Changed over HID OUTPUT items to use HID_IOF_NON_VOLATILE.

Change over MagStripe project to use HID_DESCRIPTOR_KEYBOARD() for its HID report. Change over MouseHostDevice demo to use HID_DESCRIPTOR_MOUSE() for its HID report.

Fixed ReportID not being removed from the feature/out report data array in the HID class driver when Report IDs are used.

Added new MAX() and MIN() convenience macros.

Added new HID_DESCRIPTOR_MOUSE, HID_DESCRIPTOR_KEYBOARD and HID_DESCRIPTOR_JOYSTICK macros for easy automatic creation of  basic USB HID device reports.
