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
