Add apache_reset_timeout() function for Apache1. This is needed because

Apache1 only resets the write timer, which defaults to 300 seconds, on
a successful write.  That is, if the client has gone away and Apache
attempts a write which fails it will set the conn->aborted flag but not
reset the timeout.  Assuming the PHP script is running in ignore_user_abort
mode we ignore the aborted flag, but we'll still get blown out of the water
300 seconds after the failed write unless we periodically reset the timer.
With set_time_limit(0), ignore_user_abort(true) and periodic
apache_reset_timeout() calls we can theoretically run forever which is
why I disabled this call in safe mode.
