Added flags parameter to extension_route_command(). The caller now specifies whether the command comes from the USB interface or the AP. Moved USB-specific shuffling of response to embed result code into usb_upgrade.c, so extension_route_command() can be more generic. No change to permissions/behavior for existing commands. ccd_command_wrapper() still sends vendor commands as if they come from the AP. That's fixed in the next CL.
