. 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

. the die_now flag should be static

. please_die_gracefully() is no longer needed

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.

This patch was submitted by Ian Holsman. Greg revised some names, applied
the Apache style, and namespace-prefixed the public symbols. Minor bugfix in
the use of the hook implementation macro.

* updated Apache's byterange filter to handle the new prototype. added
  error handling to the byterange filter should apr_brigade_partition()
  ever fail, which it never will unless somebody either removes the earlier
  call to apr_brigade_length() for some unknown reason or invents a new
  bucket type that is of a predetermined length but which cannot be split
  natively (or which has a split that might fail).  might as well be

pod_out; after that change, all read and write syscalls on the handles
failed because pod_in was only readable and pod_out was only writable

we could instead reverse the order of the parameters to apr_pipe_create
so that the descriptors returned by pipe() get put in the right place,
but it seems better to stick with APR terminology for what is the input
handle and what is the output handle

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
