Define my_thread_id as an unsigned type, to avoid mismatch with ulonglong. Change some parameters to this type. Use size_t in a few more places. Declare many flag constants as unsigned to avoid sign mismatch when shifting bits or applying the unary ~ operator. When applying the unary ~ operator to enum constants, explictly cast the result to an unsigned type, because enum constants can be treated as signed. In InnoDB, change the source code line number parameters from ulint to unsigned type. Also, make some InnoDB functions return a narrower type (unsigned or uint32_t instead of ulint; bool instead of ibool).
