[PATCH v2 00/25] Error handling fixes & cleanups

[Markus Armbruster <armbru@redhat.com>]

This series addresses a number of error handling issues I found while
working on error handling improvements.  It's based on my "[PULL
00/16] Qdev patches for 2020-06-23" merged into current master.

Based-on: <20200623142326.2349416-1-armbru@redhat.com>

v2:
* PATCH 04: Two more instances, in tests/check-qom-proplist
* PATCH 12: Dropped; PATCH 04 takes care of it
* PATCH 17: One more instance due to rebase; R-by kept
* PATCH 22-25: New
