Merge remote-tracking branch 'remotes/stsquad/tags/pull-testing-and-plugins-250220-1' into staging

Testing and plugin updates:

 - fix pauth TCG tests
 - tweak away rcutorture failures
 - various Travis updates
 - relax iotest size check a little
 - fix for -trace/-D clash
 - fix cross compile detection for tcg tests
 - document plugin query lifetime
 - fix missing break in plugin core
 - fix some plugin warnings
 - better progressive instruction decode
 - avoid trampling vaddr in plugins

  target/riscv: progressively load the instruction during decode
  qemu/bitops.h: Add extract8 and extract16
  tests/plugin: prevent uninitialized warning
  plugins/core: add missing break in cb_to_tcg_flags
  docs/devel: document query handle lifetimes
