Improve pledge() usability and consistency
- We now kill the program on violations like OpenBSD - We now print a message explaining which promise is needed - This change also fixes a linkage bug with thread local storage - Your sigaction() handlers should now be more thread safe A new `__pledge_mode` global has been introduced to make pledge() more customizable on Linux. For example: __attribute__((__constructor__)) static void init(void) { __pledge_mode = SECCOMP_RET_ERRNO | EPERM; } Can be used to restore our old permissive pledge() behavior.
