gaih_inet: make numeric lookup a separate routine

Browse Source

Introduce the gaih_result structure and general paradigm for cleanups
that follow to process the lookup request and return a result.  A lookup
function (like text_to_binary_address), should return an integer error
code and set members of gaih_result based on what it finds.  If the
function does not have a result and no errors have occurred during the
lookup, it should return 0 and res.at should be set to NULL, allowing a
subsequent function to do the lookup until we run out of options.
