When specifying lbr_fmt=VALUE in cpu options with an invalid VALUE, error_setg() gets triggered twice, causing an assertion failure in error_setv() which requires *errp to be NULL, preventing meaningful error messages from being displayed.
Fix this by checking visit_type_uint64()'s return value and returning early on failure, consistent with other property setters like set_string().

Naming is hard. But in general in QEMU, a host "backend" is the term
used to fullfill the request made by the device or frontend.
AudioBackend will become an abstract base class in a follow-up series.
Currently the frontend is QEMUSoundCard, we are going to drop that next.
Note that "audiodev" is the corresponding QAPI type name (or configuration).

Pass errp to load_image_targphys_as() in generic-loader and
guest-loader to capture detailed error information from the
loader functions.
Use error_prepend() instead of error_setg() to preserve the
underlying error details while adding context about which image
failed to load.

Currently load_image_targphys_as() returns -1 on file open failure or
when max size is exceeded. Add an explicit check for zero-sized files
to catch this error early, since some callers check for size <= 0.
Also, remove the redundant size > 0 check later in the function.

Introduce the REGISTER_ARRAY QOM type. This type reuses the existing
RegisterInfoArray struct. When `register_init_block' is called, it creates
a REGISTER_ARRAY object and parents it to the calling device. This way
it gets finalized when the device is. The memory region is parented to
the REGISTER_ARRAY object to ensure correct finalizing order.
The finalize function of the REGISTER_ARRAY type performs the necessary
cleaning that used to be done by `register_finalize_block'. The latter
is left empty and will be removed when all the register API users have
been refactored.

The REGISTER class (RegisterInfo struct) is currently a QOM type
inheriting from DEVICE. This class has no real purpose:
- the qdev API is not used,
- according to the comment preceding it, the object_initialize call
is here to zero-initialize the struct. However all the effective
struct attributes are then initialized explicitly.
- the object is never parented.
This commits drops the REGISTER QOM type completely, leaving the
RegisterInfo struct as a bare C struct.
The register_register_types function is left empty here because it is
reused in the next commit.

Binaries can register a QOM type to filter their machines
by filling their TargetInfo::machine_typename field.
Commit 28502121be ("system/vl: Filter machine list available
for a particular target binary") added the filter to
machine_help_func() but missed the other places where the machine
list must be filtered, such QMP 'query-machines' command used by
QTests, and select_machine(). Fix that.
