Mapping object-add to the command line as is doesn't result in nice
syntax because of the nesting introduced with 'props'. This becomes
nicer and more consistent with device_add and netdev_add when we accept
properties for the object on the top level instead.
'props' is still accepted after this patch, but marked as deprecated.

Sphinx doesn't have very good facilities for marking chunks
of documentation as "put this in the manpage only". So instead
we move the parts we want to put into both the HTML manuals
and the manpage into their own .rst.inc files, which we can
include from both the main manual rst files and a new toplevel
rst file that will be the skeleton of the qemu.1 manpage.
In this commit, just split out the parts of the documentation
that go in the manpage.

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 SPARC and PPC targets currently have a fragment of target-specific
information about the -g and -prom options which would be better placed
as part of the general documentation of those options in qemu-options.hx.
Move the relevant information to those locations.
SPARC also has a bit of text about the -M option which is out of
date and provides no useful information over the generic documentation
of that option, so just delete it.
The motivation here is again to avoid having to awkwardly include
this text into the rST version of the qemu.1 manpage.

Currently the per-target documentation for those targets that
implement semihosting includes a bit of text that goes into both the
manual and the manpage about options specific to the target. This
text is redundant with the earlier generic option description of the
semihosting option produced from qemu-options.hx. To avoid having
to create a lot of stub include files to include into the rST
generated qemu.1 manpage, roll target-specific bits of information
into the qemu-options.hx text, so the user doesn't have to look
in two places for this information.

Add a comment noting a pitfall where putting literal markup in the

means the point-of-use must handle the literal markup (which is

For good reason, vhost-user is currently built asynchronously, that
way better performance can be obtained. However, for certain use
cases such as simulation, this is problematic.
Consider an event-based simulation in which both the device and CPU
have scheduled according to a simulation "calendar". Now, consider
the CPU sending I/O to the device, over a vring in the vhost-user
protocol. In this case, the CPU must wait for the vring interrupt
to have been processed by the device, so that the device is able to
put an entry onto the simulation calendar to obtain time to handle
the interrupt. Note that this doesn't mean the I/O is actually done
at this time, it just means that the handling of it is scheduled
before the CPU can continue running.
This cannot be done with the asynchronous eventfd based vring kick
and call design.
Extend the protocol slightly, so that a message can be used for kick
and call instead, if VHOST_USER_PROTOCOL_F_INBAND_NOTIFICATIONS is
negotiated. This in itself doesn't guarantee synchronisation, but both
sides can also negotiate VHOST_USER_PROTOCOL_F_REPLY_ACK and thus get
a reply to this message by setting the need_reply flag, and ensure
synchronisation this way.
To really use it in both directions, VHOST_USER_PROTOCOL_F_SLAVE_REQ
is also needed.
Since it is used for simulation purposes and too many messages on
the socket can lock up the virtual machine, document that this should
only be used together with the mentioned features.

The qemu-option-trace.rst.inc file contains a rST documentation
fragment which describes trace options common to qemu-nbd and
qemu-img. We put this file into interop/, but we'd like to move the
qemu-nbd and qemu-img files into the tools/ manual. We could move
the .rst.inc file along with them, but we're eventually going to want
to use it for the main QEMU binary options documentation too, and
that will be in system/. So move qemu-option-trace.rst.inc to the
top-level docs/ directory, where all these files can include it via
.. include:: ../qemu-option-trace.rst.inc
This does have the slight downside that we now need to explicitly
tell Make which manuals use this file rather than relying on
a wildcard for all .rst.inc in the manual.

Some of the documentation for QEMU "tools" which are standalone
binaries like qemu-img is an awkward fit in our current 5-manual
split. We've put it into "interop", but they're not really
about interoperability.
Create a new top level manual "tools" which will be a better
home for this documentation. This commit creates an empty
initial manual; we will move the relevant documentation
files in a subsequent commit.

In many cases the target of a convert operation is a newly provisioned
target that the user knows is blank (reads as zero). In this situation
there is no requirement for qemu-img to wastefully zero out the entire
device.
Add a new option, --target-is-zero, allowing the user to indicate that
an existing target device will return zeros for all reads.

The patch adds a new additional field to the qcow2 header: compression_type,
which specifies compression type. If field is absent or zero, default
compression type is set: ZLIB, which corresponds to current behavior.
New compression type (ZSTD) is to be added in further commit.

Make it more obvious how to add new fields to the version 3 header and
how to interpret them.
The specification is adjusted so that for new defined optional fields:
1. Software may support some of these optional fields and ignore the
others, which means that features may be backported to downstream
Qemu independently.
2. If we want to add incompatible field (or a field, for which some of
its values would be incompatible), it must be accompanied by
incompatible feature bit.
Also the concept of "default is zero" is clarified, as it's strange to
say that the value of the field is assumed to be zero for the software
version which don't know about the field at all and don't know how to
treat it be it zero or not.

Currently configure's has_sphinx_build() check simply runs a dummy
sphinx-build and either passes or fails. This means that "no
sphinx-build at all" and "sphinx-build exists but is too old" are
both reported the same way.
Further, we want to assume that all the Python we write is running
with at least Python 3.5; configure checks that for our scripts, but
Sphinx extensions run with whatever Python version sphinx-build
itself is using.
Add a check to our conf.py which makes sphinx-build fail if it would
be running our extensions with an old Python, and handle this
in configure so we can report failure helpfully to the user.
This will mean that configure --enable-docs will fail like this
if the sphinx-build provided is not suitable:
Warning: sphinx-build exists but it is either too old or uses too old a Python version
ERROR: User requested feature docs
configure was not able to find it.
Install texinfo, Perl/perl-podlators and a Python 3 version of python-sphinx
(As usual, the default is to simply not build the docs, as we would
if sphinx-build wasn't present at all.)

The qtests have recently been moved to a separate subdirectory, so
the paths that are mentioned in the documentation have to be adjusted
accordingly. And some of the iotests are now always run as part of
"make check", so this information has to be adjusted here, too.

The virtfs-proxy-helper documentation is currently in
fsdev/qemu-trace-stap.texi in Texinfo format, which we
present to the user as:
* a virtfs-proxy-helper manpage
* but not (unusually for QEMU) part of the HTML docs
Convert the documentation to rST format that lives in
the docs/ subdirectory, and present it to the user as:
* a virtfs-proxy-helper manpage
* part of the interop/ Sphinx manual
There are minor formatting changes to suit Sphinx, but no
content changes. In particular I've split the -u and -g
options into each having their own description text.
