Add user-filtering to the HID report parser, so that the user code can decide which items are to be stored into the HID_ReportInfo_t structure and which should be discarded to save on RAM usage.

Changed HIDParser to only zero out important values in the Parsed HID Report Item Information structure to save cycles.

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 swapped paremeters in the HID state memory copy call while processing a HID PUSH item in the HID report parser.

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.

Fixed report data alignment issues in the MouseHostWithParser demo when X and Y movement data size is not a multiple of 8 bits.

Fixed HID Report Descriptor Parser not correctly resetting internal states when a REPORT ID element is encountered.

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.

Commit of new class abstraction APIs for all device demos other than the MIDI demo - not documented yet.

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).

Removed Tx interrupt from the USBtoSerial demo; now sends characters via polling to ensure more time for the Rx interrupt.

Fixed incorrect HID interface class and subclass values in the Mouse and KeyboardMouse demos (thanks to Brian Dickman).

Capitolised the "Descriptor_Search" and "Descriptor_Search_Comp" prefixes of the values in the DSearch_Return_ErrorCodes_t and DSearch_Comp_Return_ErrorCodes_t enums.

Minor documentation improvements.
