deal with bogus ap_listen_rec structures.

This also backs out some circumventions I and Greg Ames had added
to prefork; these are no longer necessary because of this change.

to gain control while the request is created if the proxy module
is loaded.  The purpose of this hook is to allow modules to add
input and/or output filters to the request to the origin.  While
I was at it, I made the core use this hook, so that proxy request
creation uses some of the code from the core.  This can still be
greatly improved, but this is a good start.

  Close the mod_mime file extension matching issue by (as Ken Coar suggests)
  allowing users to continue to rely on the old 1.3 behavior of matching Any

  including Handlers and Filters with the MultiviewsMatch directive for
  mod_negotiation control.  Unfortunately, the component matching occurs
  in mod_mime, so that's where this option must reside.

changed some of the style issues within the filtering code to conform to
the rest of the server.

Various incarnations of this patch have been posted to dev@httpd without
feedback.  Now that it passes all of the httpd-test cases (with the
exception of module/negotiation test which fails without mod_ssl anyway),
it is time to check it in.

Please review and test.  We are under C-T-R rules, so I'm going to take
advantage of that and commit it now.  I have tested this about as much
as I can and it seems to work from everything I can give to it.
Considering that mod_ssl was broken before this commit, this is an
improvement.

is now a required directive, which tells Apache what port to
listen on.  The ServerName directive has also been extended
to accept an optional port.  If the port is specified to the
ServerName, the server will report that port whenever it
reports the port that it is listening on.  This change was
made to ease configuration errors that stem from having a Port
directive, and a Listen directive.  In that situation, the server
would only listen to the port specified by the Listen command,
which caused a lot of confusion to users.

- substr used in APACHE_MODULE for the help string did not parse correctly
  with autoconf 2.50+ so we had to punt there anyway and use AC_HELP_STRING.
- Add APACHE_HELP_STRING define that will call AC_HELP_STRING on 2.50+
  (actually not 2.13 - look at the regex call) or do our custom variation
  of it.  This function can't have any extra spaces or it will be returned
  in the help string.  So noted.  If anyone can figure out how to insert
  a line break like 2.50+ does when we go over the 26th column, I'd
  appreciate it.  I tried and I'm way too tired to figure it out now.
  Adding this would greatly simplify two or three HELP_STRING uses.
- Switch all of those annoying WITH and ENABLE functions to use the
  APACHE_HELP_STRING.  This makes everything consistent now.  I've always
  had to go through and keep aligning everything every few months or so
  because I'm the only one who cares.  No more.  I refuse to do it any more!
  Use APACHE_HELP_STRING or be crucified.

Looks decent with autoconf-2.13 and autoconf-2.52.

See RFC 2616 13.3.4 for more details (these are SHOULD/MAY clauses, so I
think we can discard them when we are dealing with dynamic data).

support it.  This defines a symbol called AP_SIG_GRACEFUL in
ap_config_auto.h which will have the appropriate signal value.  All
direct references to SIGWINCH have been replaced with AP_SIG_GRACEFUL.

On Linux 2.0, use SIGWINCH instead since SIGUSR1 is used by glibc
2.0's user-space threading library to control threads.  All later
versions of Linux/glibc don't have this problem.  (Not to mention the
security holes in older Linux versions which make it unsuitable for
use as a web server.)  If your platform doesn't have SIGUSR1, use the
appropriate mojo in configure to define what your graceful restart
signal should be.

In theory, a configure switch could be added to allow the admin to
specify the appropriate signal that should be used.  This is left
as an exercise to the reader for now.

The docs need to be updated.  Since the signal is now configurable,
just saying SIGUSR1 for graceful restart isn't completely true.  Also,
