Add support for UTF-8
This adds a table-driven UTF-8 parser which only has a single branch for
the entire parser. UTF-8 support is essentially bolted onto the VTE
parser. Not the most elegant, but it does prevent the transition tables
from blowing up.
Instead of refactoring the syntax extension to handle both table
definitions, I've opted to copy/paste now for both simplicities sake and
because I can't see a clear path to a minimal shared solution.
