Mission Control does a lot of deprecated things. Here's a first round, including:
* TP_ERROR, not TP_ERRORS
* TpIntset, not TpIntSet
* remove signals marshallers, depend on GLib 2.30
* remove some unused internal functions
* remove support for Capabilities and ContactCapabilities.DRAFT1, leaving only
"Invalid branch: deprecated-simple"
Seems simple enough.
Thanks, fixed in git for 5.13.0
