[Qemu-devel] [PATCH 1/2] qom: add object_new_with_class()

["Radim Krčmář" <rkrcmar@redhat.com>]

object_new_with_object_class() was a close contender for the name, but
it is longer, the type system will catch possible errors, and the only
reasonable replacement would be a polymorphic function that would not
break existing users.
