* - Fixed the definition of the Endpoint_BytesInEndpoint() macro for the U4 series AVR parts
* - Fixed MIDI host Class driver MIDI_Host_SendEventPacket() routine not properly checking for Pipe ready before writing
* - Fixed use of deprecated struct initializers, removed library unused parameter warnings when compiled with -Wextra enabled
* - Fixed Still Image Host Class driver truncating the PIMA response code (thanks to Daniel)
