Renamed USB_Host_ClearPipeStall() to USB_Host_ClearEndpointStall() as the function works on an endpoint address within the attached device, and not a Pipe within the host.

Updated MS_Host_ResetMSInterface() to now perform a full Mass Storage reset sequence to prevent data corruption in the event of a device lock up or timeout (thanks to David Lyons).

Add parenthesis around the library Endianness macros that do nothing on a particular architecture to prevent operator precedence issues depending on usage.

Minor documentation corrections.
