Handle default/all/any special case in get_addr_1() to setup
->family and ->bytelen correctly.
Make get_addr_1() return ->bitlen == -2 instead of -1 to
distinguish default/all/any special case from the rest:
it is safe because all callers check ->bitlen < 0, not
explicit value -1.
Reduce intendation by one level and get rid of goto/label
to make code more readable.
