acpi: aml: add helper for Opcode Arg2 Arg2 [Dst] AML pattern
Currently AML API doesn't compose terms in form of
following pattern:
Opcode Arg2 Arg2 [Dst]
but ASL used in piix4/q35 DSDT ACPI tables uses that
form, so for clean conversion of it, AML API should
be able to handle an optional 'Dst' argumet used there.
Since above pattern is used by arithmetic/bit ops,
introduce helper that they could reuse.
It reduces code duplication in existing 5 aml_foo()
functions and also will prevent more duplication
when exiting functions are extended to support
optional 'Dst' argument.

nvdimm acpi: build ACPI NFIT table
NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT)
Currently, we only support PMEM mode. Each device has 3 structures:
- SPA structure, defines the PMEM region info
- MEM DEV structure, it has the @handle which is used to associate specified
ACPI NVDIMM device we will introduce in later patch.
Also we can happily ignored the memory device's interleave, the real
nvdimm hardware access is hidden behind host
- DCR structure, it defines vendor ID used to associate specified vendor
nvdimm driver. Since we only implement PMEM mode this time, Command
window and Data window are not needed
The NVDIMM functionality is controlled by the parameter, 'nvdimm', which
is introduced for the machine, there is a example to enable it:
-machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \

sd: sdhci: Delete over-zealous power check
This check was conditionalising SD card operation on the card being
powered by the SDHCI host controller. It is however possible
(particularly in embedded systems) for the power control of the SD card
to be managed outside of SDHCI. This can be as trivial as hard-wiring
the SD slot VCC to a constant power-rail.
This means the guest SDHCI can validly opt-out of the SDHCI power
control feature while still using the card. So delete this check to
allow operation of the card with SDHCI power control.
This is needed for at least Xilinx Zynq and Raspberry Pi, and
also makes Freescale i.MX25 work for me. The digilent Zybo board
has a public schematic which shows SD VCC hardwiring:

crypto: add QCryptoSecret object class for password/key handling
Introduce a new QCryptoSecret object class which will be used
for providing passwords and keys to other objects which need
sensitive credentials.
The new object can provide secret values directly as properties,
or indirectly via a file. The latter includes support for file
descriptor passing syntax on UNIX platforms. Ordinarily passing
secret values directly as properties is insecure, since they
are visible in process listings, or in log files showing the
CLI args / QMP commands. It is possible to use AES-256-CBC to
encrypt the secret values though, in which case all that is
visible is the ciphertext. For ad hoc developer testing though,
it is fine to provide the secrets directly without encryption
so this is not explicitly forbidden.
The anticipated scenario is that libvirtd will create a random
master key per QEMU instance (eg /var/run/libvirt/qemu/$VMNAME.key)
and will use that key to encrypt all passwords it provides to
QEMU via '-object secret,....'. This avoids the need for libvirt
(or other mgmt apps) to worry about file descriptor passing.
It also makes life easier for people who are scripting the
management of QEMU, for whom FD passing is significantly more
complex.
Providing data inline (insecure, only for ad hoc dev testing)
$QEMU -object secret,id=sec0,data=letmein
Providing data indirectly in raw format
printf "letmein" > mypasswd.txt
$QEMU -object secret,id=sec0,file=mypasswd.txt
Providing data indirectly in base64 format
$QEMU -object secret,id=sec0,file=mykey.b64,format=base64
Providing data with encryption
$QEMU -object secret,id=master0,file=mykey.b64,format=base64 \
-object secret,id=sec0,data=[base64 ciphertext],\
keyid=master0,iv=[base64 IV],format=base64
Note that 'format' here refers to the format of the ciphertext
data. The decrypted data must always be in raw byte format.
More examples are shown in the updated docs.

Now, s390-virtio-ccw is default machine and s390-ccw.img is default boot
loader. If the s390-virtio-ccw machine finds no device to load from and
errors out, then emits a panic and exits the vm. This breaks test cases
068 for s390x.
Adding the parameter of "-no-shutdown" for s390-ccw-virtio will pause VM
before shutdown.

qemu-iotests: s390x: fix test 051
The tests for ide device should only be tested for the pc
platform.
Set device_id to "drive0", and replace every "-drive file..."
by "-drive file=...,if=none,id=$device_id", then x86 and s390x
can get the common output in the test of "Snapshot mode".
Warning message expected for s390x when drive without device.
A x86 platform specific output file is also needed.

qemu-iotests: refine common.config
Replacing awk with sed, then it's easier to read.
Replacing "[ ! -z "$default_alias_machine" ]" with
"[[ $default_alias_machine ]]", then it's slightly shorter.

raw-posix: Make aio=native option binding
Traditionally, aio=native was treated as an advice that could simply be
ignored if an error occurs while initialising Linux AIO or the feature
wasn't compiled in. This behaviour was deprecated in commit
96518254
(qemu 2.3; error during init) and commit
1501ecc1 (qemu 2.5; not
compiled in).
This patch changes raw-posix to error out in these cases instead of
printing a deprecation warning.

qcow2: Point to amend function in check
If a reference count is not representable with the current refcount
order, the image check should point to qemu-img amend for increasing the
refcount order. However, qemu-img amend needs write access to the image
which cannot be provided if the image is marked corrupt; and the image
check will not mark the image consistent unless everything actually is
consistent.
Therefore, if an image is marked corrupt and the image check encounters
a reference count overflow, it cannot be fixed by using qemu-img amend
to increase the refcount order. Instead, one has to use qemu-img convert
to create a completely new copy of the image in this case.
Alternatively, we may want to give the user a way of manually removing
the corrupt flag, maybe through qemu-img amend, but this is not part of
this patch.
