[Qemu-devel] [PULL 00/10] Fix device introspection regressions

[Markus Armbruster <armbru@redhat.com>]

QMP command device-list-properties regressed in 2.1: it can crash or
leave dangling pointers behind.

-device FOO,help regressed in 2.2: it no longer works for
non-pluggable devices.  I tried to fix that some time ago[*], but my
fix failed review.  This is my second, more comprehensive try.

PATCH 1-3 fix one class of bugs involved in the regressions, PATCH 4-5
are libqtest preliminaries, PATCH 6 adds tests to demonstrate the
remaining bugs, PATCH 7-9 fix them to a degree (see PATCH 8 for
limitations), and PATCH 10 cleans up.

The following changes since commit ff770b07f34d28b79013a83989bd6c85f8f16b2f:
