Oops - with new changes to the way the device Configuration Descriptor is retrieved from the device, ensure that the correct position pointer is cast when extracting descriptor parameters.

Changed the parameters and behaviour of the USB_GetDeviceConfigDescriptor() function so that it now performs size checks and data validations internally, to simplify user code.

Pipe_ConfigurePipe() now automatically defaults IN pipes to accepting infinite IN requests, this can still be changed by calling the existing \ref Pipe_SetFiniteINRequests() function.

Changed Pipe stream functions to automatically set the pipe token, allowing them to be used on bidirectional pipes without having to explicitly call Pipe_SetPipeToken() beforehand.

Extend USB_GetDeviceConfigDescriptor() routine to require the configuration number within the device to fetch, to add support for multi-configuration devices.

Fixed incorrect ENDPOINT_EPNUM_MASK mask preventing endpoints above EP3 from being selected (thanks to Jonathan Oakley).

Removed STREAM_CALLBACK() macro - callbacks now use regular function definitions to clarify user code.

Removed DESCRIPTOR_COMPARATOR() macro - comparators should now use regular function definitions to clarify user code.

Fix to previous patch (make CDCHost demo deallocate pipes when an invalid CDC interface is skipped).

Remove the saving of the USB_GetNextDescriptorComp() return value in all host demos, since it went unused anyway; replaced with a simple check against the success error code for clarity.

Fixed CDCHost not clearing configured endpoints and resetting configured endpoints mask when a partially enumerated invalid CDC interface is skipped.

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.

Removed "Host_" section of the function names in ConfigDescriptor.h, as most of the routines can now be used in device mode on the device descriptor.

Renamed functions in the HID parser to have a "USB_" prefix and the acronym "HID" in the name.

Further module-level documentation updates.

Added support to the CDCHost demo for devices with mutiple CDC interfaces which are not the correct ACM type preceeding the desired ACM CDC interface.

Seperated out OTG, Device and Host mode demos into seperate folders for clarity. Adjusted makefiles so that the path to the LUFA library can be set in one place.
