 \brief     attribute definition for gcc/clang for extended checking

 In case the code is compiled with gcc or clang here are defines for
 attribute which allow the compiler to better issue compile time
 warning (-Wnonnull), runtime diagnostics -fsanitize=nonnull-attribute
 and possible optimize, __attribute__ ((hot)).
