* debug.cc (add_handle): Print handle value when collision detected.

Browse Source 
* dtable.cc (dtable::stdio_init): Cosmetic change.
* fhandler.h (fhandler_base::create_read_state): Protect handle.
(fhandler_pipe::create_guard): Ditto.  Always mark the handle as inheritable.
(fhandler_pipe::is_slow): Return boolean value rather than numeric 1.
* pipe.cc (fhandler_pipe::fhandler_pipe): Always flag that we need fork fixup.
(fhandler_pipe::open): Don't pass security attributes to create_guard.
(fhandler_pipe::set_close_on_exec): Don't handle guard here.
(fhandler_pipe::close): Accommodate now-protected guard handle.
(fhandler_pipe::fixup_in_child): Don't proected read_state here.
(fhandler_pipe::fixup_after_exec): Close guard handle if close_on_exec.
(fhandler_pipe::fixup_after_fork): Don't bother with guard here.
(fhandler_pipe::dup): Don't set res to non-error prematurely.  Use boolean
values where appropriate.  Protect guard and read_state.
(fhandler_pipe::create): Don't call need_fork_fixup since it is now the
default.  Don't protect read_state or guard.
* pipe.cc (fhandler_base::ready_for_read): Use bool values for "avail".
* spawn.cc (spawn_guts): Set cygheap->pid_handle as inheritable when
protecting.
* select.cc (fhandler_pipe::ready_for_read): Actually get the guard mutex for
blocking reads.
