Merge tag 'pull-10.0-testing-and-gdstub-updates-100225-1' of https://gitlab.com/stsquad/qemu into staging
testing and gdbstub updates:
- add a check-rust test to docker builds
- re-factor the qtest logic to be cleaner
- fix tests to not clock_step when no timers enabled
- roll-up log prefix into qtest_send
- cleaner error reporting when qtest_clock_set fails
- revert old deadlock fix now tests are updated
- only run full set of migration tests under HW acceleration
- support late attachment to user-mode gdbstubs
