This adds a test for having multiple BlockBackends in one BDS tree. In
this case, there is one BB for the protocol BDS and one BB for the
format BDS in a simple two-BDS tree (with the protocol BDS and BB added
first).

When bdrv_close_all() is executed, no cached data from any BDS should be
lost; the protocol BDS may not be closed until the format BDS is closed.
Otherwise, metadata updates may be lost.

In order to be able to move _filter_nbd to common.filter in the next

eight spaces), fix the line length of the comment, and add a line break

In the patch after the next, this function is moved to common.filter.
Therefore, its name should be preceded by an underscore to signify its
global availability.

To keep the code motion patch clean, we cannot rename it in the same
patch, so we need to choose some order of renaming vs. motion. It is
better to keep a supposedly global function used by only a single test
in that test than to keep a supposedly local function in a common* file
and use it from a test, so we should rename the function before moving
it.

This reverts the changes that commit
2e1280e8 applied to hw/block/fdc.c;
also, an additional case of drv->media_inserted use has crept in since,
which is replaced by a call to blk_is_inserted().

That commit changed tests/fdc-test.c, too, because after it, one less
TRAY_MOVED event would be emitted when executing 'change' on an empty
drive. However, now, no TRAY_MOVED events will be emitted at all, and
the tray_open status returned by query-block will always be false,
necessitating (different) changes to tests/fdc-test.c and iotest 118,
which is why this patch is not a pure revert of said commit.

Currently the ObjectProperty iterator API works as follows:

  ObjectPropertyIterator *iter;

  iter = object_property_iter_init(obj);
  while ((prop = object_property_iter_next(iter))) {
     ...
  }
  object_property_iter_free(iter);

This has the benefit that the ObjectPropertyIterator struct
can be opaque, but has the downside that callers need to
explicitly call a free function. It is also not in keeping
with iterator style used elsewhere in QEMU/GLib2.

This patch changes the API to use stack allocation instead:

  ObjectPropertyIterator iter;

  object_property_iter_init(&iter, obj);
  while ((prop = object_property_iter_next(&iter))) {
     ...

[AF: Fused ObjectPropertyIterator struct with typedef]
Signed-off-by: NAndreas Färber <afaerber@suse.de>

When there are many instances of a given class, registering
properties against the instance is wasteful of resources. The
majority of objects have a statically defined list of possible
properties, so most of the properties are easily registerable
against the class. Only those properties which are conditionally
registered at runtime need be recorded against the klass.

Registering properties against classes also makes it possible
to provide static introspection of QOM - currently introspection
is only possible after creating an instance of a class, which
severely limits its usefulness.

This impl only supports simple scalar properties. It does not
attempt to allow child object / link object properties against
the class. There are ways to support those too, but it would
make this patch more complicated, so it is left as an exercise
for the future.

There is no equivalent to object_property_del() provided, since
classes must be immutable once they are defined.

Here, we try to append additional help to the error message by

play nicely with the errno part.  tests/qemu-iotests/070.out shows the
resulting mess:

Switch to error_setg() and error_append_hint().  Result:

    Invalid extent lines:

The code looks like it tries to check for both qemu_init_main_loop()
and qemu_get_aio_context() failure in one conditional.  In fact,
qemu_get_aio_context() can fail only after qemu_init_main_loop()
failed.

Simplify accordingly: check for qemu_init_main_loop() error directly,
without bothering to improve its error message.  Call
qemu_get_aio_context() only when qemu_get_aio_context() succeeded.  It
can't fail then, so no need to check.
