* errno.cc (seterrno_from_win_error): Fix debugging output.

Browse Source 
* fhandler.cc (fhandler_base::fstat): Move to inline method in fhandler.h.
(fhandler_base::set_io_handle): Ditto.
* fhandler.h (fhandler_base): Make some methods inline.
* fhandler_console.cc (fhandler_console::write_normal): Make buffer larger.
* sigproc.h (sigframe::sigframe): Actually use set ebp parameter correctly.
* spawn.cc (spawn_guts): Set dwProcessId when exec'ing.  Just exit immediately
after reparenting.
* syscalls.cc: Sprinkle sigframe stuff throughout.
* wait.cc (wait4): Set signal frame here.
* dcrt0.cc (__api_fatal): Don't rely on small_printf to display errors.  Always
display problems to the console, if possible.
