Extract a library for common binder-related things

Initially this just unifies the various copies of we have of
new_binder_exception(), and adds a variation for service-specific
errors. (I thought this would help me solve my problem with missing
error info, but it turns out I was wrong.) I'm intending to move more
things here though to facilitate reuse.
