avoid C-style cast warnings from GCC for wait-related macros
* lo-utils.h (octave_wait): New class.
* lo-cutils.h, lo-cutils.c (octave_wifexited, octave_wexitstatus,
octave_wifsignaled, octave_wtermsig, octave_wcoredump,
octave_wifstopped, octave_wstopsig, octave_wifcontinued):
New functions.
* toplev.cc, pager.cc, syscalls.cc: Use octave_wait functions instead
of WIFEXITED, WEXITSTATUS, WIFSIGNALED, WTERMSIG, WCOREDUMP,
WIFSTOPPED, WSTOPSIG, WIFCONTINUED macros.
