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.

   install their filters. [Ryan Bloom]

http_protocol.c:
*) move check_first_conn_error() up in the file; no actual changes
*) add checked_bputstrs(), checked_bflush(), and checked_bputs(). These are
   copies of ap_rvputs(), ap_rflush(), and ap_rputs() respectively. The
   users of the checked_* functions will be independent of filtering changes
   to the ap_r* functions.

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.
