uvc-gadget: factor out uvc protocol and stream handling code
uvc-gadget.c has been getting cluttered with functions related to
UVC protocol handling and stream handling. Additionally, it is forseen
that we might want stream handling to be modular for different system
models. Factor out code related to UVC protocol handling to uvc.c (and
uvc.h) and code related to stream handling to stream.c (and stream.h),
and update the Makefile accordingly.
