Add a "iothread" qdev property type so devices can be hooked up to an
IOThread from the comand-line:
qemu -object iothread,id=iothread0 \
-device some-device,x-iothread=iothread0
Note that Paolo Bonzini <pbonzini@redhat.com> has suggested using QOM
links instead. This way the relationship between the objects is
reflected in QOM. There are currently shortcomings of
object_property_add_link() which prevent this use case. I will attempt
to fix them and move to QOM links in a separate series.

get_pointer()'s print() callback might return a heap allocated
string, to avoid adding dedicated get_pointer_foo for this case
convert current print() callbacks to return temporary heap
allocated string and make get_pointer() free it.

Use "drive", "chr", etc. only for legacy_name (which shows up
in -device foo,? output).

Replace assert_no_error() usages with the error_abort system.
&error_abort is passed into API calls to signal to the Error sub-system
that any errors are fatal. Removes need for caller assertions.

It is currently possible to specify things like:
-device e1000,netdev=foo,vlan=1
With this usage, whichever argument was specified last (vlan or netdev)
overwrites what was previousely set and results in a non-working
configuration. Even worse, when used with multiqueue devices,
it causes a segmentation fault on exit in qemu_free_net_client.
That patch treates the above command line options as invalid and
generates an error at start-up.
