opts: ParseTCPAddr(): extract parsing logic, consistent errors

Browse source 
Make sure we validate the default address given before using it, and
combine the parsing/validation logic so that it can be reused.

This patch also makes the errors more consistent, and uses pkg/errors
for generating them.
