Changed the return values of the <ACE_Proactor::handle_events> API to

return -1 on error, 0 on timeout, 1 on success. This has been done so
that it looks like the <ACE_Reactor::handle_events>. Previously
<ACE_Proactor::handle_events> was returning -1 on error, 0 on success
and 0 on timeout also.

Fixed the <ACE_POSIX_AIOCB_Proactor::handle_events> and
<ACE_POSIX_SIG_Proactor::handle_events> to do indefinite blocking when
ACE_INFINITE is passed. <sigwaitinfo> is used instead of
<sigtimedwait>.

Renamed the <ACE_AIO_Accept_Handler> class to more appropriate
<ACE_Notify_Pipe_Manager>.
