If grant copy is available then it will always be used in preference to
persistent maps. In this case feature-persistent should not be advertized
to the frontend, otherwise it may needlessly copy data into persistently
granted buffers.

Add the ability for the NVMe model to support both the RDS and WDS
modes in the Controller Memory Buffer.
Although not currently supported in the upstreamed Linux kernel a fork
with support exists [1] and user-space test programs that build on
this also exist [2].
Useful for testing CMB functionality in preperation for real CMB
enabled NVMe devices (coming soon).

Some USB devices have sparse interface numbering which is not able to be
passthroughed.
For example, the Sierra Wireless MC7455/MC7430:
# lsusb -D /dev/bus/usb/003/003 | egrep '1199|9071|bNumInterfaces|bInterfaceNumber'
Device: ID 1199:9071 Sierra Wireless, Inc.
idVendor 0x1199 Sierra Wireless, Inc.
idProduct 0x9071
bNumInterfaces 5
bInterfaceNumber 0
bInterfaceNumber 2
bInterfaceNumber 3
bInterfaceNumber 8
bInterfaceNumber 10
In this case, the interface numbers are 0, 2, 3, 8, 10 and not the
0, 1, 2, 3, 4 that QEMU tries to claim.
This change allows sparse USB interface numbering.
Instead of only claiming the interfaces in the range reported by the USB
device through bNumInterfaces, QEMU attempts to claim all possible
interfaces.

The getter and setter of TYPE_APIC_COMMON property "id" are
apic_common_get_id() and apic_common_set_id().
apic_common_get_id() reads either APICCommonState member uint32_t
initial_apic_id or uint8_t id into an int64_t local variable. It then
passes this variable to visit_type_int().
apic_common_set_id() uses visit_type_int() to read the value into a
local variable, which it then assigns both to initial_apic_id and id.
While the state backing the property is two unsigned members, 8 and 32
bits wide, the actual visitor is 64 bits signed.
Change getter and setter to use visit_type_uint32(). Then everything's
uint32_t, except for @id.

Switch to use QNum/uint where appropriate to remove i64 limitation.
The input visitor will cast i64 input to u64 for compatibility
reasons (existing json QMP client already use negative i64 for large
u64, and expect an implicit cast in qemu).
Note: before the patch, uint64_t values above INT64_MAX are sent over
json QMP as negative values, e.g. UINT64_MAX is sent as -1. After the
patch, they are sent unmodified. Clearly a bug fix, but we have to
consider compatibility issues anyway. libvirt should cope fine,
because its parsing of unsigned integers accepts negative values
modulo 2^64. There's hope that other clients will, too.

Commit e987c37aee ("hw/i386: check if
nvdimm is enabled before plugging") introduced a check to reject nvdimm
hotplug if -machine pc,nvdimm=on was not given.
This check executes after pc_dimm_memory_plug() has already completed
and does not reverse the effect of this function in the case of failure.
Perform the check before calling pc_dimm_memory_plug(). This fixes the
following abort:
$ qemu -M accel=kvm -m 1G,slots=4,maxmem=8G \
-object memory-backend-file,id=mem1,share=on,mem-path=nvdimm.dat,size=1G
(qemu) device_add nvdimm,memdev=mem1
nvdimm is not enabled: missing 'nvdimm' in '-M'

First, let vtd_do_iommu_translate() return a status, so that we
explicitly knows whether error occured. Meanwhile, we make sure that
IOMMUTLBEntry is filled in in that.
Then, cleanup vtd_iommu_translate a bit. So even with PT we'll get a log
now. Also, remove useless assignments.

We have converted many of the DPRINTF() into traces. This patch does the
last 100+ ones.
To debug VT-d when error happens, let's try enable:
-trace enable="vtd_err*"
This should works just like the old GENERAL but of course better, since
we don't need to recompile.
Similar rules apply to the other modules. I was trying to make the
prefix good enough for sub-module debugging.
