fix some more signalling issues:
. in ONE_PROCESS mode, bail out immediately for SIGHUP and
SIGINT
Note that if you send HUP or INT and have cgid then cgid won't
go away. If you generate the interrupt signal from the httpd
terminal then cgid will go away, [I guess] because SIGINT gets sent
to the process group. Perhaps just_die() needs to have logic to
send to other processes in the group for ONE_PROCES mode

For SIGHUP in the server processes, we attempt to go away immediately,
just as for SIGTERM. If we deadlock because of some module or library
issue then SIGKILL will come soon enough.
Stop dorking with SIGTERM and SIGHUP in make_child(). That makes it
kind of hard for the caller to set up for ONE_PROCESS mode.

the input handle to the pod (used by child processes) needs to be non-blocking
before this, no requests could be processed by prefork since after connect
from the client prefork would block reading the pod
the write handle to the pod probably doesn't have to be non-blocking, but
getting EAGAIN for the pipe-full condition, rather than blocking, is nice
for now since it would tend to indicate that something is FUBAR; on the other
hand, this probably needs to change in order to support more than 4K workers

First pass at the pipe_of_death logic for the prefork MPM. This does

%D is the time delta from the time the request was received to the time the headers are sent

%t results in the string t=xxx. Thus the config directive above will result in this header
