Fix KeyboardHost ClassDriver demo; boot protocol keyboard report structure in the Host Mode HID Class driver uses the full keycode array from the attached device.
Added new USB_GetHIDReportSize() function to the HID report parser to retrieve the size of a given report by its ID.
More additions to the unfinished HID Host Class Driver.
SetIdle requests to the HID device driver with a 0 idle period (send changes only) now only affect the requested HID interface within the device, not all HID interfaces.
Apply correct fix to the HID report parser for PUSH items - current HID item attribute stack was being copied in the wrong direction.
Fixed HID report parser not resetting the FEATURE item count when a REPORT ID item is encountered.
Fixed memory corruption HID report parser when too many COLLECTION or PUSH items were processed.
Make RNDIS device class driver include the CDC device class driver header, so that it can inherrit the required CDC functional descriptor macro.
Make HID host class driver include the HID report parser.
Split out common defines/types from class drivers into a seperate common class driver directory.
Make central USB Class driver dispatch headers, used for both device and host modes.
Removed scheduler and memory allocation libraries.
Added new EVENT_USB_StartOfFrame event in the library to indicate the start of each USB frame (when generated).
