fixes #295 boolean options should use C99 bool type

fixes #275 nng_pipe_getopt_ptr() missing?
fixes #285 nng_setopt_ptr MIS
fixes #297 nng_listener/dialer_close does not validate mode

This change adds some missing APIs, and changes others.
In particular, certain options are now of type bool, with size
of just one.  This is a *breaking* change for code that uses those
options -- NNG_OPT_RAW, NNG_OPT_PAIR1_POLY, NNG_OPT_TLS_VERIFIED.
