Subject: [PATCH] Annotate generated static inline functions with
 __attribute__((unused))

clang may generate an unused-function warning on a function that is
marked 'static inline'. This patch annotates those static inline
functions generated by dbus-binding-tool with '__attribute__((unused))'
to suppress the warning.
