[Qemu-devel] [RFC 0/5] -object/object-add support custom location and 2nd stage initialization

[Igor Mammedov <imammedo@redhat.com>]

Adds optional interfaces that objects could implement if
they need to:
  1. perform an additional initialization after object properties are set
  2. be placed not in '/objects' container

Series depends on 2 PULL requests in flight from Andreas & Luiz
with fixes for QOM interfaces and object-add monitor/QMP command.
Git tree for testing:
