Command block_passwd always fails since
Commit c01c214b69 "block: remove all encryption handling APIs"
(v2.10.0) turned block_passwd into a stub that always fails, and
hardcoded encryption_key_missing to false in query-named-block-nodes
and query-block.
Commit ad1324e044 "block: remove 'encryption_key_missing' flag from
QAPI" just landed. Complete the cleanup job: remove block_passwd.

QMP commands return their response as a generated QAPI type, which the
monitor core converts to JSON via QObject.
query-qmp-schema's response is the generated introspection data. This
is a QLitObject since commit 7d0f982bfb "qapi: generate a literal
qobject for introspection", v2.12). Before, it was a string. Instead
of converting QLitObject / string -> QObject -> QAPI type
SchemaInfoList -> QObject -> JSON, we take a shortcut: the command is
'gen': false, so it can return the QObject instead of the QAPI type.
Slightly simpler and more efficient.
The next commit will filter the response for output policy, and this
is easier in the SchemaInfoList representation. Drop the shortcut.
This replaces the manual command registration by a generated one. The
manual registration makes the command available before the machine is
built by passing flag QCO_ALLOW_PRECONFIG. To keep it available
there, we need need to add 'allow-preconfig': true to its definition
in the schema.

New option -compat lets you configure what to do when deprecated
interfaces get used. This is intended for testing users of the
management interfaces. It is experimental.
-compat deprecated-input=<input-policy> configures what to do when
deprecated input is received. Input policy can be "accept" (accept
silently), or "reject" (reject the request with an error).
-compat deprecated-output=<out-policy> configures what to do when
deprecated output is sent. Output policy can be "accept" (pass on
unchanged), or "hide" (filter out the deprecated parts).
Default is "accept". Policies other than "accept" are implemented
later in this series.
For now, -compat covers only syntactic aspects of QMP, i.e. stuff
tagged with feature 'deprecated'. We may want to extend it to cover
semantic aspects, CLI, and experimental features.
Note that there is no good way for management application to detect
presence of -compat: it's not visible output of query-qmp-schema or
query-command-line-options. Tolerable, because it's meant for
testing. If running with -compat fails, skip the test.

This converts object-add from 'gen': false to the ObjectOptions QAPI
type. As an immediate benefit, clients can now use QAPI schema
introspection for user creatable QOM objects.
It is also the first step towards making the QAPI schema the only
external interface for the creation of user creatable objects. Once all
other places (HMP and command lines of the system emulator and all
tools) go through QAPI, too, some object implementations can be
simplified because some checks (e.g. that mandatory options are set) are
already performed by QAPI, and in another step, QOM boilerplate code
could be generated from the schema.

Bitmap's source persistence is transported over the migration stream and
the destination mirrors it. In some cases the destination might want to
persist bitmaps which are not persistent on the source (e.g. the result
of merging bitmaps from a number of layers on the source when migrating
into a squashed image) but currently it would need to create another set
of persistent bitmaps and merge them.
This patch adds a 'transform' property to the alias map which allows
overriding the persistence of migrated bitmaps both on the source and
destination sides.
