Eduardo Habkost 4a15e5bef8 scripts/codeconverter: Update to latest version
I'm not documenting every single change in the codeconverter
script because most of that code will be deleted once we finish
the QOM code conversion.  This patch updates the script to the
latest version that was used to perform changes in the QOM code.
