fix a number of warnings and other issues:
• sig_t detection was a bit insane, it is a function-pointer type after all • fix uninitialised variable in c_select which led to mistakenly accepting invalid (nōn-numeric) input and acting, randomly, upon it • keep SIGCHLD blocked in child after forking longer, for job list manip • block SIGCHLD ifdef DEBUG_LEAKS to not run job foo during/after afreeall • fix annoying ISO C90 vs. C99 (un)signed constant warning
