Merge ~cjwatson/launchpad:py3-tagfiles-bytes into launchpad:master

[Colin Watson]

Always parse tagfiles as bytes

Most field values are restricted to ASCII anyway, but dealing with everything as bytes makes our data types more consistent, allowing them to work on Python 3.

Apologies for the size of this MP; I couldn't manage to reduce it while making it still reasonably obvious what was going on. It ended up being simplest to convert pretty much all the tagfile parsing logic at once.

[Cristian Gonzalez (cristiangsp)]

Bytes everywhere!
