SAL_UNUSED_PARAMETER (expanding to __attribute__ ((unused)) for GCC) is used to annotate legitimately unused parameters, so that static analysis tools can tell legitimately unused parameters from truly unnecessary ones. To that end, some patches for external modules are also added, that are only applied when compiling with GCC and add necessary __attribute__ ((unused)) in headers.
