New option -compat lets you configure what to do when deprecated
interfaces get used. This is intended for testing users of the
management interfaces. It is experimental.
-compat deprecated-input=<input-policy> configures what to do when
deprecated input is received. Input policy can be "accept" (accept
silently), or "reject" (reject the request with an error).
-compat deprecated-output=<out-policy> configures what to do when
deprecated output is sent. Output policy can be "accept" (pass on
unchanged), or "hide" (filter out the deprecated parts).
Default is "accept". Policies other than "accept" are implemented
later in this series.
For now, -compat covers only syntactic aspects of QMP, i.e. stuff
tagged with feature 'deprecated'. We may want to extend it to cover
semantic aspects, CLI, and experimental features.
Note that there is no good way for management application to detect
presence of -compat: it's not visible output of query-qmp-schema or
query-command-line-options. Tolerable, because it's meant for
testing. If running with -compat fails, skip the test.

The possible choices for panic, reset and watchdog actions are inconsistent.
"-action panic=poweroff" should be renamed to "-action panic=shutdown"
on the command line. This is because "-action panic=poweroff" and
"-action watchdog=poweroff" have slightly different semantics, the first
does an unorderly exit while the second goes through qemu_cleanup(). With
this change, -no-shutdown would not have to change "-action panic=pause"
"pause", just like it does not have to change the reset action.
"-action reboot=none" should be renamed to "-action reboot=reset".
This should be self explanatory, since for example "-action panic=none"
lets the guest proceed without taking any action.

The "XVP" (Xen VNC Proxy) extension defines a mechanism for a VNC client
to issue power control requests to trigger graceful shutdown, reboot, or
hard reset.
This option is not enabled by default, since we cannot assume that users
with VNC access implicitly have administrator access to the guest OS.
Thus is it enabled with a boolean "power-control" option e.g.
-vnc :1,power-control=on
While, QEMU can easily support shutdown and reset, there's no easy way
to wire up reboot support at this time. In theory it could be done by
issuing a shutdown, followed by a reset, but there's no convenient
wiring for such a pairing in QEMU. It also isn't possible to have the
VNC server directly talk to QEMU guest agent, since the agent chardev is
typically owned by an external mgmt app.

The current default action of pausing a guest after a panic event
is received leaves the responsibility to resume guest execution to the
management layer. The reasons for this behavior are discussed here:
https://lore.kernel.org/qemu-devel/52148F88.5000509@redhat.com/
However, in instances like the case of older guests (Linux and
Windows) using a pvpanic device but missing support for the
PVPANIC_CRASHLOADED event, and Windows guests using the hv-crash
enlightenment, it is desirable to allow the guests to continue
running after sending a PVPANIC_PANICKED event. This allows such
guests to proceed to capture a crash dump and automatically reboot
without intervention of a management layer.
Add an option to avoid stopping a VM after a panic event is received,
by passing:
-action panic=none
in the command line arguments, or during runtime by using an upcoming
QMP command.

-action event=action
Which can be used to specify the existing options above in the
following format:
-action reboot=none|shutdown
-action shutdown=poweroff|pause
-action watchdog=reset|shutdown|poweroff|pause|debug|none|inject-nmi
This is done in preparation for adding yet another option of this

* the synopsis line for the documentation has drifted out of sync
with the synopsis line in the DEF() macro (used for "-help" output)
* the synopsis line in the DEF() macro is missing a "][" between
the sleep= part and the rr= part
* the synopsis line doesn't indicate that rrsnapshot is an optional
part of the rr=mode,rrfile=filename subgrouping
* we don't document that sleep=on can't be used with shift=auto
or align=on
* the rr option description had some minor grammar and formatting
errors and was a bit terse
* in commit f1f4b57e88 in 2015 the documentation of the sleep=
suboption got added between the two paragraphs defining general
behaviour of the icount option. This meant that the second
paragraph talking about the behaviour of "this option" reads as
if it's talking about sleep=on, when it's really describing -icount
as a whole. The paragraph is better moved back up to above the
sleep= section.
* the summary text displayed in "-help" output didn't mention

Merge remote-tracking branch 'remotes/philmd-gitlab/tags/fw_cfg-20200704' into staging
firmware (and crypto) patches
- add the tls-cipher-suites object,
- add the ability to QOM objects to produce data consumable
by the fw_cfg device,
- let the tls-cipher-suites object implement the
FW_CFG_DATA_GENERATOR interface.
This is required by EDK2 'HTTPS Boot' feature of OVMF to tell
the guest which TLS ciphers it can use.

On the host OS, various aspects of TLS operation are configurable.
In particular it is possible for the sysadmin to control the TLS
cipher/protocol algorithms that applications are permitted to use.
* Any given crypto library has a built-in default priority list
defined by the distro maintainer of the library package (or by
upstream).
* The "crypto-policies" RPM (or equivalent host OS package)
provides a config file such as "/etc/crypto-policies/config",
where the sysadmin can set a high level (library-independent)
policy.
The "update-crypto-policies --set" command (or equivalent) is
used to translate the global policy to individual library
representations, producing files such as
"/etc/crypto-policies/back-ends/*.config". The generated files,
if present, are loaded by the various crypto libraries to
override their own built-in defaults.
For example, the GNUTLS library may read
"/etc/crypto-policies/back-ends/gnutls.config".
* A management application (or the QEMU user) may overide the
system-wide crypto-policies config via their own config, if
they need to diverge from the former.
Thus the priority order is "QEMU user config" > "crypto-policies
system config" > "library built-in config".
Introduce the "tls-cipher-suites" object for exposing the ordered
list of permitted TLS cipher suites from the host side to the
guest firmware, via fw_cfg. The list is represented as an array
of bytes.
The priority at which the host-side policy is retrieved is given
by the "priority" property of the new object type. For example,
"priority=@SYSTEM" may be used to refer to
"/etc/crypto-policies/back-ends/gnutls.config" (given that QEMU
uses GNUTLS).
The firmware uses the IANA_TLS_CIPHER array for configuring
guest-side TLS, for example in UEFI HTTPS Boot.

And as we're at it, also be a bit more descriptive what 9pfs is

The documentation of our -s and -gdb options is quite old; in
particular it still claims that it will cause QEMU to stop and wait
for the gdb connection, when this has not been true for some time:
you also need to pass -S if you want to make QEMU not launch the
guest on startup.
Improve the documentation to mention this requirement in the
executable's --help output, the documentation of the -gdb option in
the manual, and in the "GDB usage" chapter.
Includes some minor tweaks to these paragraphs of documentation
since I was editing them anyway (such as dropping the description
of our gdb support as "primitive").

This commit contains hand-written fixes for some issues with the
autogenerated rST fragments in qemu-options.hx:
* Sphinx complains about the UTF-8 art table in the documentation of
the -drive option. Replace it with a proper rST format table.
* rST does not like definition list entries with no actual
definition, but it is possible to work around this by putting a
single escaped literal space as the definition line.
* The "-g widthxheight" option documentation suffers particularly
badly from losing the distinction between italics and fixed-width
as a result of the auto conversion, so put it back in again.
* The script missed some places that use the |qemu_system| etc
macros and need to be marked up as parsed-literal blocks.
* The script autogenerated an expanded out version of the
contents of qemu-option-trace.texi; replace it with an
qemu-option-trace.rst.inc include.
This is sufficient that we can enable inclusion of the
option documentation from invocation.rst.

The default NIC model for QEMU varies per machine type, and is liable to
change across machine type versions. Documenting e1000 NIC as the
default for PC/i386 is thus misleading to users at best. In particular
the PC q35 machine type switched to use e1000e, but only in machine
type versions after 2.11.
Rather than try to explain which NIC model is used for each machine
type version, remove mention of e1000 as the default, and steer users
towards always specifying their desired model.

The qemu-block-drivers documentation is currently in
docs/qemu-block-drivers.texi in Texinfo format, which we present
to the user as:
* a qemu-block-drivers manpage
* a section of the main qemu-doc HTML documentation
Convert the documentation to rST format, and present it to
the user as:
* a qemu-block-drivers manpage
* part of the system/ Sphinx manual
This follows the same pattern we've done for qemu-ga and qemu-nbd.
We have to drop a cross-reference from the documentation of the
-cdrom option back to the qemu-block-drivers documentation, since
they're no longer within the same texinfo document.
As noted in a comment, the manpage output is slightly compromised
due to limitations in Sphinx. In an ideal world, the HTML output
would have the various headings like 'Disk image file formats'
as top-level section headings (which then appear in the overall
system manual's table-of-contents), and it would not have the
section headings which make sense only for the manpage like
'synopsis', 'description', and 'see also'. Unfortunately, the
mechanism Sphinx provides for restricting pieces of documentation
is limited to the point of being flawed: the 'only::' directive
is implemented as a filter that is applied at a very late stage
in the document processing pipeline, rather than as an early
equivalent of an #ifdef. This means that Sphinx's process of
identifying which section heading markup styles are which levels
of heading gets confused if the 'only::' directive contains
section headings which would affect the heading-level of a
later heading. I have opted to prioritise making the HTML format
look better, with the compromise being that in the manpage
the 'Disk image file formats' &c headings are top-level headings
rather than being sub-headings under the traditional 'Description'
top-level section title.

It's been deprecated since QEMU v3.1. We've explicitly asked in the
deprecation message that people should speak up on qemu-devel in case
they are still actively using the bluetooth part of QEMU, but nobody
ever replied that they are really still using it.
I've tried it on my own to use this bluetooth subsystem for one of my
guests, but I was also not able to get it running anymore: When I was
trying to pass-through a real bluetooth device, either the guest did
not see the device at all, or the guest crashed.
Even worse for the emulated device: When running
qemu-system-x86_64 -bt device:keyboard
QEMU crashes once you hit a key.
So it seems like the bluetooth stack is not only neglected, it is
completely bitrotten, as far as I can tell. The only attention that
this code got during the past years were some CVEs that have been
spotted there. So this code is a burden for the developers, without
any real benefit anymore. Time to remove it.
Note: hw/bt/Kconfig only gets cleared but not removed here yet.
Otherwise there is a problem with the *-softmmu/config-devices.mak.d
dependency files - they still contain a reference to this file which
gets evaluated first on some build hosts, before the file gets
properly recreated. To avoid breaking these builders, we still need
the file around for some time. It will get removed in a couple of
weeks instead.

It is accessed as a framebuffer but the color palette can be set.
