Coverity complains about qemu_memfd_create() (CID 1385858) because
we calculate a bit position htsize which could be up to 63, but
then use it in "1 << htsize" which is a 32-bit integer calculation
and could push the 1 off the top of the value.
Silence the complaint bu using "1ULL"; this isn't a bug in
practice since a hugetlbsize of 4GB is not very plausible.

The recently introduced qom-list-properties QMP command raised
a question what properties it (and its cousin - device-list-properties)
can possibly print - only those defined by DeviceClass::props
or dynamically created in TypeInfo::instance_init() so properties created
elsewhere won't show up and this behaviour might confuse the user.
For example, PIIX4 does that from piix4_pm_realize() via
piix4_pm_add_propeties():
object_property_add_uint8_ptr(OBJECT(s), ACPI_PM_PROP_ACPI_ENABLE_CMD,
&acpi_enable_cmd, NULL);
This adds a note to the command descriptions about the limitation.

If CONFIG_SECCOMP is undefined, the option 'elevatedprivileges' remains
compiled. This would make libvirt set the corresponding capability and
then trigger failure during guest startup. This patch moves the code
regarding seccomp command line options to qemu-seccomp.c file and
wraps qemu_opts_foreach finding sandbox option with CONFIG_SECCOMP.
Because parse_sandbox() is moved into qemu-seccomp.c file, change
seccomp_start() to static function.

The checksum field of a NC-SI packet contains a value that may be
included in each command and response. The verification is optional
but the Linux driver does so when a non-zero value is provided. Let's
extend the model to compute the checksum value and exercise a little
more the Linux driver.
See section "8.2.2.3 - 2's Complement Checksum Compensation" in the
Network Controller Sideband Interface (NC-SI) Specification for more
details.

When setting up an outgoing user mode networking TCP connection,
disable the Nagle algorithm in the host-side connection. Either the
guest is already doing Nagle, in which case there is no point in doing
it twice, or it has chosen to disable it, in which case we should
respect that choice.
This change speeds up GDB remote debugging over TCP over user mode
networking (with GDB runing on the guest) by multiple orders of
magnitude, and has been part of the local patches applied by pkgsrc
since 2012 with no reported ill effects.

This patch removes the current hackery where IOREQ_TYPE_PCI_CONFIG
requests are handled by faking PIO to 0xcf8 and 0xcfc and replaces it
with direct calls to pci_host_config_read/write_common().
Doing so necessitates mapping BDFs to PCIDevices but maintaining a simple
QLIST in xen_device_realize/unrealize() will suffice.
NOTE: whilst config space accesses are currently limited to
PCI_CONFIG_SPACE_SIZE, this patch paves the way to increasing the
limit to PCIE_CONFIG_SPACE_SIZE when Xen gains the ability to
emulate MCFG table accesses.

When global_log_dirty is enabled VRAM modification tracking never
worked correctly. The address that is passed to xen_hvm_modified_memory()
is not the effective PFN but RAM block address which is not the same
for VRAM.
We need to make a translation for this address into PFN using
physmap. Since there is no way to access physmap properly inside
xen_hvm_modified_memory() let's make it a global structure.
