Resolve console-mode stdout file descriptor issues for mod_perl by replacing

it in lockstep with unix stdout replacement (in pre_config).  Only an undetached
server (console mode single process/debug) will retain the original stdout, just
as on unix.  Inspired by research of Tom and myself (CHANGES to credit both).
