To avoid repetition of switch upstream port specific data in the
CXLDeviceState structure it will be necessary to access the switch USP
specific data from mailbox callbacks. Hence move it to cxl_device.h so it
is no longer an opaque structure.

By moving the parts of the mailbox command handling that are CCI type
specific out to the caller, make the main handling code generic. Rename it
to cxl_process_cci_message() to reflect this new generality.
Change the type3 mailbox handling (reused shortly for the switch
mailbox CCI) to take a snapshot of the mailbox input data rather
than operating on it in place. This reduces the chance of bugs
due to aliasing going forwars.

Handle output IO messages in the transmit (TX) virtqueue.
It allocates a VirtIOSoundPCMBuffer for each IO message and copies the
data buffer to it. When the IO buffer is written to the host's sound
card, the guest will be notified that it has been consumed.
The lifetime of an IO message is:
1. Guest sends IO message to TX virtqueue.
2. QEMU adds it to the appropriate stream's IO buffer queue.
3. Sometime later, the host audio backend calls the output callback,
virtio_snd_pcm_out_cb(), which is defined with an AUD_open_out()
call. The callback gets an available number of bytes the backend can
receive. Then it writes data from the IO buffer queue to the backend.
If at any time a buffer is exhausted, it is returned to the guest as
completed.
4. If the guest releases the stream, its buffer queue is flushed by
attempting to write any leftover data to the audio backend and
releasing all IO messages back to the guest. This is how according to
the spec the guest knows the release was successful.

This adds a non-cryptographic grade implementation of the
model for the True Random Number Generator (TRNG) component
in AMD/Xilinx Versal device family.
This implements all 3 modes defined by the actual hardware
specs, all of which selectable by guest software at will
at anytime:
1) PRNG mode, in which the generated sequence is required to
be reproducible after reseeded by the same 384-bit value
as supplied by guest software.
2) Test mode, in which the generated sequence is required to
be reproducible ater reseeded by the same 128-bit test
seed supplied by guest software.
3) TRNG mode, in which non-reproducible sequence is generated
based on periodic reseed by a suitable entropy source.
This model is only intended for non-real world testing of
guest software, where cryptographically strong PRNG or TRNG
is not needed.
This model supports versions 1 & 2 of the device, with
default to be version 2; the 'hw-version' uint32 property
can be set to 0x0100 to override the default.
Other implemented properties:
- 'forced-prng', uint64
When set to non-zero, mode 3's entropy source is implemented
as a deterministic sequence based on the given value and other
deterministic parameters.
This option allows the emulation to test guest software using
mode 3 and to reproduce data-dependent defects.
- 'fips-fault-events', uint32, bit-mask
bit 3: Triggers the SP800-90B entropy health test fault irq
bit 1: Triggers the FIPS 140-2 continuous test fault irq

The flattened format (currently output by QEMU) is used by makedumpfile
only when it is outputting a vmcore to a file which is not seekable. The
flattened format functions essentially as a set of instructions of the
form "seek to the given offset, then write the given bytes out".
The flattened format can be reconstructed using makedumpfile -R, or
makedumpfile-R.pl, but it is a slow process because it requires copying
the entire vmcore. The flattened format can also be directly read by
crash, but still, it requires a lengthy reassembly phase.
To sum up, the flattened format is not an ideal one: it should only be
used on files which are actually not seekable. This is the exact
strategy which makedumpfile uses, as seen in the implementation of
"write_buffer()" in makedumpfile [1]. However, QEMU has always used the
flattened format. For compatibility it is best not to change the default
output format without warning. So, add a flag to DumpState which changes
the output to use the normal (i.e. raw) format. This flag will be added
to the QMP and HMP commands in the next change.

Now that we have converted to qdev, we can use the newer
qemu_input_handler_register() API rather than the legacy
qemu_add_kbd_event_handler().
Since we only have one user, take the opportunity to convert
from scancodes to QCodes, rather than using
qemu_input_key_value_to_scancode() (which adds an 0xe0
prefix and encodes up/down indication in the scancode,
which our old handler function then had to reverse). That
lets us drop the old state field which was tracking whether
we were halfway through a two-byte scancode.

Instead of exposing the ugly hack of how we represent arrays in qdev (a
static "foo-len" property and after it is set, dynamically created
"foo[i]" properties) to boards, add an interface that allows setting the
whole array at once.
Once all internal users of devices with array properties have been
converted to use this function, we can change the implementation to move
away from this hack.

Extend the blocker interface so that a blocker can be registered for
one or more migration modes. The existing interfaces register a
blocker for all modes, and the new interfaces take a varargs list
of modes.
Internally, maintain a separate blocker list per mode. The same Error
object may be added to multiple lists. When a block is deleted, it is
removed from every list, and the Error is freed.
No functional change until a new mode is added.

Create a mode migration parameter that can be used to select alternate
migration algorithms. The default mode is normal, representing the
current migration algorithm, and does not need to be explicitly set.
No functional change until a new mode is added, except that the mode is
shown by the 'info migrate' command.

Current code does:
- register pre_2_10_vmstate_dummy_icp with "icp/server" and instance
dependinfg on cpu number
- for newer machines, it register vmstate_icp with "icp/server" name
and instance 0
- now it unregisters "icp/server" for the 1st instance.
This is wrong at many levels:
- we shouldn't have two VMSTATEDescriptions with the same name
- In case this is the only solution that we can came with, it needs to
be:
* register pre_2_10_vmstate_dummy_icp
* unregister pre_2_10_vmstate_dummy_icp
* register real vmstate_icp
Created vmstate_replace_hack_for_ppc() with warnings left and right
that it is a hack.

We have lots of cases where we are using an instance_id==0 when we
should be using VMSTATE_INSTANCE_ID_ANY (-1). Basically everything
that can have more than one needs to have a proper instance_id or -1

The networking subsystem may wish to use defer_call(), so move the code
to util/ where it can be reused.
As a reminder of what defer_call() does:
This API defers a function call within a defer_call_begin()/defer_call_end()
section, allowing multiple calls to batch up. This is a performance
optimization that is used in the block layer to submit several I/O requests
at once instead of individually:
defer_call_begin(); <-- start of section
...
defer_call(my_func, my_obj); <-- deferred my_func(my_obj) call
defer_call(my_func, my_obj); <-- another
defer_call(my_func, my_obj); <-- another
...
defer_call_end(); <-- end of section, my_func(my_obj) is called once

This patch removes the code that ufs-lu was duplicating from
scsi-hd and allows them to share code.
It makes ufs-lu have a virtual scsi-bus and scsi-hd internally.
This allows scsi related commands to be passed thorugh to the scsi-hd.
The query request and nop command work the same as the existing logic.
Well-known lus do not have a virtual scsi-bus and scsi-hd, and
handle the necessary scsi commands by emulating them directly.
