If SIGP is set, the 'Wait for Reselection' command should jump
immediately to the address stored in the second DWORD of the
instruction. This fixes spurious hangs in the HP-UX 11.11
installer when the SIGP bit gets set by the kernel before the
'Wait for Reselection' command is executed by SCRIPTS.

HP-UX checks this register after sending data to the target. If there's no valid
information present, it assumes the client disconnected because the kernel sent
to much data. Implement at least some of the SBCL functionality that is possible
without having a real SCSI bus.

Build fails with gcc 9:
CC ppc64-softmmu/hw/scsi/virtio-scsi.o
hw/scsi/virtio-scsi.c: In function ‘virtio_scsi_do_tmf’:
hw/scsi/virtio-scsi.c:265:39: error: taking address of packed member of ‘struct virtio_scsi_ctrl_tmf_req’ may result in an unaligned pointer value [-Werror=address-of-packed-member]

| ^~~~~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
All the fields in struct virtio_scsi_ctrl_tmf_req are naturally aligned,
so we could in theory drop QEMU_PACKED. Unfortunately, the header file
is imported from linux which already has the packed attribute. Trying to
fix that in the update-linux-headers.sh script is likely to produce
ugliness. Turn the call to virtio_tswap32s() into an assignment instead.

The CPUID code will call kvm_arch_get_supported_cpuid() and, even though
it is undef kvm_enabled() so it never runs for user-mode emulators,
sometimes clang will not optimize it out at -O0.
That could be considered a compiler bug, however at -O0 we give it
a pass and just add the stubs.

The configure script checks multiple times whether it works in a git
repository and it does this by "test -e "${source_path}/.git" in 4 cases
but in one case where it tries to enable werror "-d" is used there which
fails on git worktrees as .git is a file then and not a directory.
This changes the test to "-e" as other occurrences.

Some multiboot images could be in the ELF format. In the current
implementation QEMU fails because we try to load these images
as a PVH image.
In order to fix this issue, we should try multiboot first (we
already check the multiboot magic header before to load it).
If it is not a multiboot image, we can try the PVH loader.

As NVDIMM support is looming for ARM and SPAPR, let's
move the acpi_nvdimm_state to the generic machine struct
instead of duplicating the same code in several machines.
It is also renamed into nvdimms_state and becomes a pointer.
nvdimm and nvdimm-persistence become generic machine options.
They become guarded by a nvdimm_supported machine class member.
We also add a description for those options.

Commit fcfab7541 ("qmp-shell: learn to send commands with quoted
arguments") introduces the usage of Python 'shlex' to handle quoted
arguments, but it accidentally broke generation of nested JSON
structs.
shlex drops quotes, which breaks parsing of the nested struct.
cmd='blockdev-create job-id="job0 foo" options={"driver":"qcow2","size":16384,"file":{"driver":"file","filename":"foo.qcow2"}}'
shlex.split(cmd)
['blockdev-create',
'job-id=job0 foo',
'options={driver:qcow2,size:16384,file:{driver:file,filename:foo.qcow2}}']
Replace with a regexp to split while respecting quoted strings and preserving quotes:
re.findall(r'''(?:[^\s"']|"(?:\\.|[^"])*"|'(?:\\.|[^'])*')+''', cmd)
['blockdev-create',
'job-id="job0 foo"',

If we're doing an out-of-tree build of Sphinx, then we
copy some extra spurious files to the install directory
as part of 'make install':
qemu-ga-qapi.texi
qemu-ga-ref.7
qemu-ga-ref.7.pod
qemu-ga-ref.html
qemu-ga-ref.txt
qemu-qmp-qapi.texi
qemu-qmp-ref.7
qemu-qmp-ref.7.pod
qemu-qmp-ref.html
qemu-qmp-ref.txt
because these have been built into build/docs/interop along
with the Sphinx interop documents. Filter them out of the
set of files we install when we're installing the Sphinx-built
manual files. (They are installed into their correct locations
as part of the main install-doc target already.)

Audio drivers now get an Audiodev * as config paramters, instead of the
global audio_option structs. There is some code in audio/audio_legacy.c
that converts the old environment variables to audiodev options (this
way backends do not have to worry about legacy options). It also
contains a replacement of -audio-help, which prints out the equivalent
-audiodev based config of the currently specified environment variables.
Note that backends are not updated and still rely on environment
variables.
Also note that (due to moving try-poll from global to backend specific
option) currently ALSA and OSS will always try poll mode, regardless of
environment variables or -audiodev options.

This patch adds documentation of an -audiodev command line option, that
deprecates the old QEMU_* environment variables for audio backend
configuration. It's syntax is similar to existing options (-netdev,
-device, etc):
-audiodev driver_name,property=value,...
Although now it's possible to specify multiple -audiodev options on
command line, multiple audio backends are not supported yet.

I had to include an enum for audio sampling formats into qapi, but that
meant duplicating the audfmt_e enum. This patch replaces audfmt_e and

This patch is mostly a search-and-replace, except for switches where the

This patch adds structures into qapi to replace the existing
configuration structures used by audio backends currently. This qapi
will be the base of the -audiodev command line parameter (that replaces
the old environment variables based config).
This is not a 1:1 translation of the old options, I've tried to make
them much more consistent (e.g. almost every backend had an option to
specify buffer size, but the name was different for every backend, and
some backends required usecs, while some other required frames, samples
or bytes). Also tried to reduce the number of abbreviations used by the
config keys.
Some of the more important changes:
* use `in` and `out` instead of `ADC` and `DAC`, as the former is more
user friendly imho
* moved buffer settings into the global setting area (so it's the same
for all backends that support it. Backends that can't change buffer
size will simply ignore them). Also using usecs, as it's probably more
user friendly than samples or bytes.
* try-poll is now an alsa backend specific option (as all other backends
currently ignore it)

Combine all variant in a single handler. As source and destination
have different element sizes, we can't use gvec expansion. Expand
manually. Also watch out for overlapping source and destination
registers. Use a safe evaluation order depending on the operation.

Very similar to VECTOR LOAD WITH LENGTH, just the opposite direction.
Properly probe write access before modifying memory.

As we only store one element, there is nothing to consider regarding
exceptions.

Instead of checking e.g. the first access on every touched page, we should
check the actual access, otherwise we might get false positives when Low
Address Protection (LAP) is active. As probe_write() can only deal with
accesses to one page, we have to loop.
Use i64 for the length, although not needed - easier to reuse
TCG temps we already have in the translation functions where this will
be used. Also allow it to be used from other helpers.
