ap_ prefix, not apr_

The following configuration file demonstrates the problem:

<IfModule mod_rewrite.c>
RewriteEngine on
RewriteMap    quux-map       prg:/tmp/apache-2.0/map.quux.pl
RewriteRule   ^/~quux/(.*)$  /~quux/${quux-map:$1}
</IfModule>

After this config file is parsed, the only statement in the config
tree is the last statement in the IfModule container ("RewriteRule blah
blah").

The problem is that when ap_build_config_sub() handles this type of
construct, it moves *current to the end of the list before returning.
If this construct were the first thing in the file, the caller would
set conftree to *current, not realizing that there were list elements
before *current.  The caller doesn't have addressability to those list
elements.

With this change, ap_build_config_sub() sets *conftree before
walking *current to the end of the list.

socketpair instead of sockets created with AF_UNIX.  There is very little
chance this will work anywhere other than Linux, but it is a start.  I
have a machine with two virtual hosts, which are started as two different
users.  When I make requests for each virtual host, they pass the request
to the correct child process.  It is possible for a virtual host to have
multiple child processes all with the same user ID, and they all share
the responsability for answering requests.

There are a lot of bugs in this code, and it is not for the faint
hearted, but it works, and that's saying quite a bit in my mind.

Docs coming tomorrow.  Right now, it's time to sleep.

Still to do: decide at config time whether any modules need dbm, whether
             to use the native one or sdbm, etc.

likely to work anyplace other than Linux right now either.

descriptors.  I am setting this aside for a day or two, and then I will
come back and finish the implementation on a new OS.  This is highlighting
the need for descriptor passing in APR.

HOW IT WORKS:
    In the config file, the sysadmin specified:
         ChildPerUserID  uid gid num_processes
    and in each virtual host:
         AssignUserID  uid gid

    The MPM creates a unix domain socket for each uid/gid pair, and if any
    child processes are left over, one for the default user and group
    specified in the main config.

    When a child process is started, it looks at what it's user id and group
    id are supposed to be.  It then inserts the correct socket into it's
    listen array, and switches to the uid and gid specified.

    When a request comes in, whichever child gets the request looks at which
    child process it is actually for, and if it isn't for the current
    process, the request gets forwarded through the unix domain socket to the
    correct child process.  From there, processing continues normally.

    Currently, no requests are forwarded, but everything seems to be working.

ONE_PROCESS.  This allows Apache to start up without detaching from
the controlling terminal, but also not going into single process mode.
The main purpose of this patch is to make it very easy to debug the
child process startup code.
