eliminate OCTAVE_USE_WINDOWS_API and OCTAVE_USE_OS_X_API from header files * sysdep.h, sysdep.cc (MINGW_SIGNAL_CLEANUP): Delete macro. (w32_set_quiet_shutdown, MINGW_signal_cleanup): Delete functions. (sysdep_cleanup): Do w32_set_quiet_shutdown here for Windows systems. * sighandlers.h, sighandlers.cc (my_friendly_exit): Call sysdep_cleanup instead of using MINGW_SIGNAL_CLEANUP macro. * oct-conf-post.in.h (OCTAVE_USE_WINDOWS_API, OCTAVE_USE_OS_X_API): Delete macro definitions.
