fixes #901 shorter option get/set functions for all types

- Renamed internal nng_*_getx/setx methods with "nni" prefix
- Moved stream get/set option definition macros to options.h and added "NNI_" prefix
- "_PTR" variant of get/set option definition macros is for when first arg is passed as pointer (`nng_stream *s` vs `nng_pipe s`)
- New get/set option functions for `nng_socket` are `nng_socket_get_X` eschewing the previous `nng_getopt` pattern
- Macro-fy legacy getopt/setopt and implement in terms of "new" API
- nng_setopt* use "new" shorter API.  Add missing uint64 set functions.
- Shorter get/set option functions get own man page and old getopt/setopt link to them
- Built with -DNNG_ENABLE_DOC=ON and part of central libnng index
- Update copyright
