Implement Doorbel Buffer Config command (Section 5.7 in NVMe Spec 1.3)
and Shadow Doorbel buffer & EventIdx buffer handling logic (Section 7.13
in NVMe Spec 1.3). For queues created before the Doorbell Buffer Config
command, the nvme_dbbuf_config function tries to associate each existing
SQ and CQ with its Shadow Doorbel buffer and EventIdx buffer address.
Queues created after the Doorbell Buffer Config command will have the
doorbell buffers associated with them when they are initialized.
In nvme_process_sq and nvme_post_cqe, proactively check for Shadow
Doorbell buffer changes instead of wait for doorbell register changes.
This reduces the number of MMIOs.
In nvme_process_db(), update the shadow doorbell buffer value with
the doorbell register value if it is the admin queue. This is a hack
since hosts like Linux NVMe driver and SPDK do not use shadow
doorbell buffer for the admin queue. Copying the doorbell register
value to the shadow doorbell buffer allows us to support these hosts
as well as spec-compliant hosts that use shadow doorbell buffer for
the admin queue.

This change moves the code that connects the SoC UART's to serial_hd's
to the machine.
It makes each UART a proper child member of the SoC, and then allows the
machine to selectively initialize the chardev for each UART with a
serial_hd.
This should preserve backwards compatibility, but also allow multi-SoC
boards to completely change the wiring of serial devices from the
command line to specific SoC UART's.
This also removes the uart-default property from the SoC, since the SoC
doesn't need to know what UART is the "default" on the machine anymore.
I tested this using the images and commands from the previous
refactoring, and another test image for the ast1030:

This commit adds a passthrough for PMBUS_IC_DEVICE_ID to allow Renesas
voltage regulators to return the integrated circuit device ID if they
would like to.
The behavior is very device specific, so it hasn't been added to the
general PMBUS model. Additionally, if the device ID hasn't been set,
then the voltage regulator will respond with the error byte value. The
guest error message will change slightly for IC_DEVICE_ID with this
commit.

When A/UX configures the CDROM device it sends a truncated MODE SELECT request
for page 1 (MODE_PAGE_R_W_ERROR) which is only 6 bytes in length rather than
10. This seems to be due to bug in Apple's code which calculates the CDB message
length incorrectly.
The work at [1] suggests that this truncated request is accepted on real
hardware whereas in QEMU it generates an INVALID_PARAM_LEN sense code which
causes A/UX to get stuck in a loop retrying the command in an attempt to succeed.
Alter the mode page request length check so that truncated requests are allowed
if the SCSI_DISK_QUIRK_MODE_PAGE_TRUNCATED quirk is enabled, whilst also adding a
trace event to enable the condition to be detected.

Both MacOS and A/UX make use of vendor-specific MODE SELECT commands with PF=0
to identify SCSI devices:
- MacOS sends a MODE SELECT command with PF=0 for the MODE_PAGE_VENDOR_SPECIFIC
(0x0) mode page containing 2 bytes before initialising a disk
- A/UX (installed on disk) sends a MODE SELECT command with PF=0 during SCSI
bus enumeration, and gets stuck in an infinite loop if it fails
Add a new SCSI_DISK_QUIRK_MODE_PAGE_VENDOR_SPECIFIC_APPLE quirk to allow both
PF=0 MODE SELECT commands and implement a MODE_PAGE_VENDOR_SPECIFIC (0x0)
mode page which is compatible with MacOS.

During SCSI bus enumeration A/UX sends a MODE SENSE command to the CDROM with
the DBD bit unset and expects the response to include a block descriptor. As per
the latest SCSI documentation, QEMU currently force-disables the block
descriptor for CDROM devices but the A/UX driver expects the requested block
descriptor to be returned.
If the block descriptor is not returned in the response then A/UX becomes
confused, since the block descriptor returned in the MODE SENSE response is
used to generate a subsequent MODE SELECT command which is then invalid.
Add a new SCSI_DISK_QUIRK_MODE_SENSE_ROM_USE_DBD quirk to allow this behaviour
to be enabled as required. Note that an additional workaround is required for
the previous SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk which must never
return a block descriptor even though the DBD bit is left unset.

One of the mechanisms MacOS uses to identify CDROM drives compatible with MacOS
is to send a custom MODE SELECT command for page 0x30 to the drive. The
response to this is a hard-coded manufacturer string which must match in order
for the CDROM to be usable within MacOS.
Add an implementation of the MODE SELECT page 0x30 response guarded by a newly
defined SCSI_DISK_QUIRK_MODE_PAGE_APPLE_VENDOR quirk bit so that CDROM drives
attached to non-Apple machines function exactly as before.

Developers often run QEMU without installing. The bundle mechanism
allows to look up files which should be present in installation even in
such a situation.
It is a general mechanism and can find any files in the installation
tree. The build tree will have a new directory, qemu-bundle, to
represent what files the installation tree would have for reference by
the executables.
Note that it abandons compatibility with Windows older than 8. The
extended support for the prior version, 7 ended more than 2 years ago,
and it is unlikely that someone would like to run the latest QEMU on
such an old system.

It is not advisable to execute an object_dynamic_cast() to poke into
bus->qbus.parent and follow it up with a C cast into the PnvPHB type we
think we got.
In fact this is not needed. There is nothing sophisticated being done
with the PHB object retrieved during root_port_realize() for both PHB3
and PHB4. We're retrieving a PHB reference just to access phb->chip_id
and phb->phb_id and use them to define the chassis/slot of the root
port.
phb->phb_id is already being passed to pnv_phb_attach_root_port() via
the 'index' parameter. Let's also add a 'chip_id' parameter to this
function and assign chassis and slot right there. This will spare us
from the hassle of accessing the PHB object inside realize().

for GCC < 5.0 and Clang < 3.8. We don't support such old compilers
at all anymore, so we can remove these lines now. We keep the wrapper
function, though, since they are easier to read and help to make sure that
the parameters have the right types.
