Reinstate P_FSTRACE, with different semantics:
...
* Never send a SIGCHLD to the parent if P_FSTRACE is set.
* Do not permit mixing ptrace(2) and procfs; only permit using the one that
was attached.

Remove remnants of P_FSTRACE, which is no longer used.

Changed killpg1() to 'succeed' even if a process group consists of
...
SZOMB processes only; the POSIX.1 definition of a background process
group implies that kill(2)ing such a process group must succeed.

make coredump() use more sensible error returns (even though they're
...
not used by anything, for now), and implement MNT_NOCOREDUMP by checking
whether or not MNT_NOCOREDUMP is set on the file system where the dump
would land (i.e. the file system of the process's current working
directory), and disallowing the core dump if it's set.

in coredump(), check the SUGID bit rather than testing various parts

Fix various signal handling bugs:
...
* If we got a stopping signal while already stopped with the same signal,
the second signal would sometimes (but not always) be ignored.
* Signals delivered by the debugger always pretended to be stopping
signals.
* PT_ATTACH still didn't quite work right.
