This patch converts the f_sourcesink and f_loopback file to the USB-function module. Both functions shares a few common utility functions which are currently implemented in g_zero.c itself. This patch moves the common code into the sourcesink file and creates one module out of the the two functions (source sink and loop back). The g_zero gadget is function specific to source sink and loop back to set a few options. This Symbol dependency enforces a modul load right now.
