in some server restart scenarios.

It relied on getting SIGHUP to die, but it wasn't careful
about establishing the SIGHUP handling it needed so after
apachectl restart, SIGHUP was ignored since the new cgid
daemon process inherited a signal(SIGHUP,SIG_IGN) done by
the MPM during its restart logic.

Autoconf path variables (like --sysconfdir, --sbindir, etc). exp_foo is
the "expanded" version, which means that all internal variable references
have been interpolated.  rel_foo is the same as $exp_foo, only relative
to $prefix if they share a common path.

This will be used in apxs.in and apachectl.in to allow Apache installs
to be relocated as long as the same relative directory structure remains.
Currently this is only possible if you use the Apache layout, but not
with other layouts or any overridden --foodir paths.

Now, for a graceful restart the worker threads won't exit until they
are told that the queue has been drained and no more connections will
ever be added.

go away before the workers...  introduce separate XXX_may_exit flags
for our different categories of threads so that a future fix for
graceful shutdown can terminate them in the right order

rename signal_workers() to signal_threads() and give it a parameter
so it knows whether or not termination should be graceful

this commit doesn't change the behavior in any noticeable way;  the
flags used to tell threads to go away are still set at about the same
time

buffer size is small.

This will help us avoid a malloc/free pair when executing mod_rewrite
rules that use $1/$2/etc to reference sequences in the matched pattern.

Note: I've also submitted this change as a patch for PCRE, but because
the next PCRE release isn't planned until later this year I'm
committing it to the httpd-2.0 copy of PCRE in the meantime.

call for the initialization to be valid in the macro (Thx to Jeff!).
In the meantime, bump down the error logging until we deal with true
default and configured setting information ala 1.3.

  Here's the patch that really sucks.  old_listeners points to an array
  of apr_socket objects already destroyed by their cleanups, and in any
  case they now live in invalid memory.  Extend their lifetimes.

  This implies that the process pool grows on every restart for no good
  reason.  One possible solution is to let the old pconf survive until
  the new pconf is alive.  Another is to create the listeners in a subpool
  of process->pool, destroyed after the old_listeners are closed.

  Either which way, a better solution exists, but this closes the immediate
  bug.  [How haven't we been segfaulting in unix on restarts before this
  patch, gurus?]
