This brings in the first batch of testing updates for the next
release. The main bulk of these is Daniel and Thomas' cleanups of the
qtest timeouts and allowing meson control them. There are a few minor
tweaks I've made to some avocado and gitlab tests.

The big update is support for reading register values in TCG plugins.
After feedback from Akihiko I've left all the smarts to the plugin and
made the interface a simple "all the registers" dump. There is a
follow on patch to make the register code a little more efficient by
checking disassembly. However we can leave the door open for future
API enhancements if the translator ever learns to reliably know when
registers might be touched.

Ping for final review? I'd at least like to get the testing stuff
cleared out of my tree.
