Pekka Paalanen 6ae243f91e Add leak sanitizer suppressions ... ASan will detect leaks also outside of the code we build, and sometimes that external code leaks and we cannot work around it. Then we need to suppress the leak reports to make our own ASan testing succeed. This commit only introduces the suppressions file, making use of it CI is for another time. This file is useful for manual targeted testing as below. Start by suppressing two functions what weston-keyboard client ends up calling, suppressing leak reports like these: Indirect leak of 96 byte(s) in 3 object(s) allocated from: #0 An error occurred
