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.

blocking (previously, both handles were non-blocking).

ap_set_pipe_timeout() is now the only way to manipulate the
blocking state of the pipe.  Pass -1 for timeout to make it
blocking; pass 0 for timeout to make it non-blocking.

ap_block_pipe() is gone.

A few minor bugs were fixed along the way.

OS-specific notes:

non-Unix in general:

Only Unix/BeOS currently has the optimization to keep track of the blocking
state.  This is used to avoid syscalls as well as to handle ap_put_os_file(),
which is a case where we don't know the blocking state of the handle we are
given.

OS/2:

ap_set_pipe_timeout() with timeout value > 0: The code didn't play with
the blocking state before and it doesn't still.  I did add logic for special
timeout values 0 and -1 to play with the blocking state.

ap_create_pipe():  old logic didn't do anything with the blocking state
of the second handle; it still doesn't; hopefully it is blocking

pre-BONE BEOS:

old code t...
