Rename usbg_create_gadget() to usbg_create_vid_pid().
dd usbg_create_gadget() to allow gadget creation
with given attributes and strings. Add usbg_set_gadget_attrs()
which allow to set all attributes with one call. Add
usbg_set_gadget_strs() which allow to set all strings with
one call.
Gadget structure creation and initialization has been moved to
usbg_create_empty_gadget() to avoid copy-paste same code in
usbg_create_gadget_vid_pid() and usbg_create_gadget().
