Add NNG_OPT_DOMAIN and NNG_OPT_SOCKNAME support for legacy compat.

The NNG_OPT_SOCKNAME option is settable, to a limit of 64 bytes.
The NNG_OPT_DOMAIN is read-only, but changes to match the setting
of the NNG_OPT_RAW field.  New applications should not use the
NNG_OPT_DOMAIN option -- it is provided solely for use with the
legacy NN_DOMAIN option in the compatibility layer.
