In which case is dumb search-and-replace of tvb_get_string with
tvb_get_string_enc and ENC_ASCII an easy way to make (part of) the API
transition? We'll still have to audit for dissectors that really meant
ENC_SOMETHING_ELSE (probably ENC_UTF8 in most cases) but it'll be easy
progress without any behavioural changes.
