major overhaul of the way make handle jobs, inspired by dpb: instead of forking a "job" per target, and having that job further fork separate commands, have make maintain a list of jobs, indexed by pid of currently running commands, and handle process termination continuation-style. This has lots of benefits: - make is responsible for most printing, so we no longer need pipes nor job control: make -j jobs see the tty. - no more special-casing for jobs that don't really execute anything. - unify code for make -jn and make -B, including signal handlers and job waiting. So make -n, make -q, +cmd now run commands in the same way in all cases. - unified more accurate error-reporting, as make knows precisely which command failed. Commands are tagged with their lines, and we display failing commands in silent mode. - fine-grained "expensive" command handling (recursion limiter). Do it per-command instead of per-target. Moreover, signal response is now simpler, as we just block the signals in a small critical sections, test for events, and sigpause (thanks a lot to guenther@ and millert@), so running make is now almost always paused without any busy-waiting. Thanks to everyone who tested and gave input.
