Apache to share information.

1)  Move the calling of APR after Apache decides which MPM is run, but
    before Apache generates the Makefiles and related files.  This allows
    Apache to setup the threading cache values, while still allowing APR
    to generate APRVARS in time for Apache to use it.

2)  Setup the cache files correctly for RUN_NOW configured subdirectories.

This allows people to specify --disable-threads on Apache's configure
command line, and APR respects it.  This is the first step to fixing a
problem introduced by making Apache call APR's configure script before
making any config decisions.

Basically, Apache now runs APR's configure script first.  APR's configure
script has been setup to create a new file, APRVARS.  APRVARS is basically
all of the environment variables that APR wants to export to the program
that is using it.  This allows the calling program to "source" APRVARS
and get those environment variables.

Removed hack to make platforms use -ldl.

APR can modify the ap_socket_t as it sees fit.  It may choose to
modify the ap_socket_t on functions which only read from the ap_socket_t
conceptually.

Note: http_connection::ap_new_apr_connection() passes its ap_socket_t
arg to one of the changed functions, so const was removed there also.

a bug I introduced earlier today, because it uses the APR_FILES_AS_SOCKETS
to let us use the pipe of death in a poll call.  With this change, dexter
becomes much more portable.  Dexter used to try to set the pipe
non-blocking on it's own, but it only tried one argument to fcntl.  There
are at least four different arguments to fcntl based on what platform you
are on.  APR gets rid of that ugliness for us.

ap_select in ap_config.h.  The only file that used ap_select() was
prefork.c.  I have modified prefork.c to use select instead of ap_select.
In the future, this should be modified to use ap_poll like the rest of the
Unix MPMs.  There are other MPMs that are continuing to use select, but this
too should change in time.

fix the error checking for one return from ap_poll, and use ap_pcalloc to
allocate the listenfds array.  By using listenfds, we can avoid making
an unnecessary call to ap_create_tcp_socket.
