target/i386: emulate 64-bit ring 0 for linux-user if LM feature is set
32-bit binaries can run on a long mode processor even if the kernel
is 64-bit, of course, and this can have slightly different behavior;
for example, SYSCALL is allowed on Intel processors.
Allow reporting LM to programs running under user mode emulation,
so that "-cpu" can be used with named CPU models even for qemu-i386
and even without disabling LM by hand.
Fortunately, most of the runtime code in QEMU has to depend on HF_LMA_MASK
or on HF_CS64_MASK (which is anyway false for qemu-i386's 32-bit code
segment) rather than TARGET_X86_64, therefore all that is needed is an
update of linux-user's ring 0 setup.

target/i386: ignore CPL0-specific features in user mode emulation
Features such as PCID are only accessible through privileged operations,
and therefore have no impact on any user-mode operation. Allow reporting
them to programs running under user mode emulation, so that "-cpu" can be
used with more named CPU models.
XSAVES would be similar, but it doesn't make sense to provide it until
XSAVEC is implemented.
With this change, all CPUs up to Broadwell-v4 can be emulate. Skylake-Client
requires XSAVEC, while EPYC also requires SHA-NI, MISALIGNSSE and TOPOEXT.
MISALIGNSSE is not hard to implement, but I am not sure it is worth using
a precious hflags bit for it.

Export the bits to guests that indicate immunity to hardware

003f230e37d7 ("machine: Tweak the order of topology members in struct
CpuTopology") changes the meaning of MachineState.smp.cores from "the
number of cores in one package" to "the number of cores in one die"
and doesn't fix other uses of MachineState.smp.cores. And because of
the introduction of cluster, now smp.cores just means "the number of
cores in one cluster". This clearly does not fit the semantics here.
And before this error message, WHvSetPartitionProperty() is called to
set prop.ProcessorCount.
So the error message should show the prop.ProcessorCount other than
"cores per cluster" or "cores per package".

net/vhost-net: do not assert on null pointer return from tap_get_vhost_net()
When 'vhost=off' or no vhost specific options at all are passed for the tap
net-device backend, tap_get_vhost_net() can return NULL. The function
net_init_tap_one() does not call vhost_net_init() on such cases and therefore

escc: emulate dip switch language layout settings on SUN keyboard
SUN Type 4, 5 and 5c keyboards have dip switches to choose the language layout
of the keyboard. Solaris makes an ioctl to query the value of the dipswitches
and uses that value to select keyboard layout. Also the SUN bios like the one
in the file ss5.bin uses this value to support at least some keyboard layouts.
However, the OpenBIOS provided with qemu is hardcoded to always use an US
keyboard layout.
Before this patch, qemu allways gave dip switch value 0x21 (US keyboard),
this patch uses a command line switch like
"-global escc.chnA-sunkbd-layout=de" to select dip switch value. A table is
used to lookup values from arguments like:
-global escc.chnA-sunkbd-layout=fr
-global escc.chnA-sunkbd-layout=es
But the patch also accepts numeric dip switch values directly:
-global escc.chnA-sunkbd-layout=0x2b
-global escc.chnA-sunkbd-layout=43
Both values above are the same and select swedish keyboard as explained in
table 3-15 at
https://docs.oracle.com/cd/E19683-01/806-6642/new-43/index.html
Unless you want to do a full Solaris installation but happen to have
access to a Sun bios file, the easiest way to test that the patch works
is to:
qemu-system-sparc -global escc.chnA-sunkbd-layout=sv -bios /path/to/ss5.bin
If you already happen to have a Solaris installation in a qemu disk image
file you can easily try different keyboard layouts after this patch is
applied.

raw_co_getlength is called by handle_aiocb_write_zeroes, which is not a coroutine

ui/dbus: win32 support
D-Bus doesn't support fd-passing on Windows (AF_UNIX doesn't have
SCM_RIGHTS yet, but there are other means to share objects. I have
proposed various solutions upstream, but none seem fitting enough atm).
To make the "-display dbus" work on Windows, implement an alternative
D-Bus interface where all the 'h' (FDs) arguments are replaced with
'ay' (WSASocketW data), and sockets are passed to the other end via
WSADuplicateSocket().

scripts: add a XML preprocessor script
gdbus-codegen doesn't support conditions or pre-processing.
Rather than duplicating D-Bus interfaces for win32 adaptation, let's
have a preprocess step, so we can have platform-specific interfaces.
The python script is based on
https://github.com/peitaosu/XML-Preprocessor, with bug fixes, some
testing and replacing lxml dependency with the built-in xml module.
This preprocessing syntax style is not very common, but is similar to
the one provided by WiX (https://wixtoolset.org/docs/v3/overview/preprocessor/)
or wixl, that we adopted in QEMU for packaging the guest agent.
