[v2,00/17] maintainer updates for feb25 (qtest, gdbstub, plugins) pre-PR

Message

Another month and another set of updates from across my maintainer
trees. They include:

  * qtest set/step clock cleanups

It seems the earlier patch to avoid deadlock when shutting down was
overly broad. So in this series after a little clean-up to the qtest
reply code we tighten up some checks for steps that make no sense and
eventually revert the original deadlock avoiding patch.

  * reducing migration test scope depending on accel

Fabino's continued work on the migration tests and avoiding them
taking too much of the overall test execution time. KVM guests still
get the full range and we smoke test TCG guests.

  * gdbstub late attachment

These are Ilya's patches to make it easier to debug heavily
multi-process linux-user invocations. Comes with documentation and
a test case ;-)

  * plugins

Fix a compiler false positive.

I intend to send the PR next week, the following patches still need review:

  tests/qtest: rename qtest_send_prefix and roll-up into qtest_send
  tests/qtest: don't attempt to clock_step while waiting for virtio ISR
  tests/docker: replicate the check-rust-tools-nightly CI job
