* fhandler.h (fhandler_pipe::fixup_in_child): Declare new function.

Browse Source 
(fhandler_console::invisible_console): Declare new variable.
(fhandler_console::need_invisible): Ditto.
(fhandler_console::has_a): Ditto.
* fhandler_console.cc (set_console_state_for_spawn): Eliminate return value.
Set up an invisible console if necessary prior to spawning.
(fhandler_console::invisible_console): Define.
* fhandler_tty.cc (fhandler_tty_slave::open): Use
fhandler_console::invisible_console to setup an invisible console.
* pipe.cc (fhandler_pipe::fixup_in_child): Define new function from
fixup_after_exec.
(fhandler_pipe::fixup_after_exec): Use fixup_in_child when appropriate.
(fhandler_pipe::fixup_after_fork): Ditto.
* spawn.cc (handle): Reorganize and modernize a little.
(spawn_guts): Rely on set_console_state_for_spawn to set the console into the
right state but don't create the process with "detached" flag if we have no
controlling tty since that confuses 'cmd'.
* dtable.cc (dtable::stdio_init): Don't set console as controlling terminal if
we have an invisible console.
* sigproc.cc (child_info::sync): Use correct name in ForceCloseHandle1.
