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

Added new USB_Host_ClearPipeStall() convenience function to clear a stall condition on an attached device's endpoint.

Added new USB_Host_GetDeviceDescriptor() convenience function to retrieve the attached device's Device descriptor.

Make Pipe_ConfigurePipe() mask the given endpoint number against PIPE_EPNUM_MASK to ensure the endpoint IN direction bit is cleared to prevent endpoint type corruption.

Fix documentation mentioning Pipe_GetCurrentToken() function when real name is Pipe_GetPipeToken().

Changed per-device controller preprocessor checks over to per-device series for better device control.

Fixed error in Endpoint.c using HSOFI rather than SOFI for counting elapsed milliseconds.

Fixes to the MIDI device demos (ClassDriver, LowLevel); discard unused read-in events from the host, use standard MIDI event structure in low level demo rather than sending individual bytes.

Converted Host mode demos to schedulerless. Fixed host mode broken due to earlier Start-of-frame event experiments.

Copy and convert incomplete Bluetooth Host demo to the library.
