[PATCH v5 00/10] qtests: Check accelerator available at runtime via QMP 'query-accels'

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Series fully reviewed.

Hi,

This series aims at having accelerator-independent qtests
by querying a QEMU instance at runtime to check the list
of built-in accelerators.

First we add the 'query-accels' QMP command,
then we add the qtest_has_accel() method to libqtest,
finally we use this new method to allow running
bios-tables-test on KVM-only builds.

Since v5:
- Removed patch 10 (Markus, patch justification not clear)
  'qtest/qmp-cmd-test: Make test build-independent from accelerator'
- Removed patch 12 (Alex, icount / record/replay issue)
  'tests/meson: Only build softfloat objects if TCG is selected (again)'
- Sorted @Accelerator QAPI enum (Eric)
- Added R-b/T-b

Since v4:
- Added Markus review comments
- Added R-b/A-b tags

Since v3:
- Addressed Markus & Drew review comments
- Added qtest/migration-test patch

Since v2:
- Addressed Eric & Paolo review comments

Since v1:
- kept over-engineered union (I don't how to do simple enum)
- dropped arm-cpu-features patches for now
- fixed typos (Eric)
- rename qtest_has_accel (Thomas)
- probe accel with machine none previous qtest (Paolo)
- iterate over QAPI enum (Markus)

Eric's suggestion of conditional QAPI didn't worked out,
as accelerator definitions are poisoned.

Phil.
