59807e2098 docs/devel/writing-monitor-commands: Repair a decade of rot
The tutorial doesn't match reality since at least 2013.  Repairing it
involves fixing the following issues:

* Update for commit 6d32717155 (aio / timers: Remove alarm timers):
  replace the broken examples.  Instead of having one for returning a
  struct and another for returning a list of structs, do just one for
  the latter.  This resolves the FIXME added in commit
  e218052f92 (aio / timers: De-document -clock) back in 2014.

* Update for commit 895a2a80e0 (qapi: Use 'struct' instead of 'type'
  in schema).

* Update for commit 3313b6124b (qapi: add qapi2texi script): add
  required documentation to the schema snippets, and drop section
  "Command Documentation".

* Update for commit a3c45b3e62 (qapi: New special feature flag
  "unstable"): supply the required feature, deemphasize the x- prefix.

* Update for commit dd98234c05 (qapi: introduce x-query-roms QMP
  command): rephrase from "add new command" to "examine existing
  command".

* Update for commit 9492718b7c (qapi misc: Elide redundant has_FOO in
  generated C): hello-world's message argument no longer comes with a
  has_message, add a second argument that does.

* Update for moved and renamed files.

While there, update QMP version output to current output.

4ed49feb44 migration/ram: Introduce 'mapped-ram' migration capability
Add a new migration capability 'mapped-ram'.

The core of the feature is to ensure that RAM pages are mapped
directly to offsets in the resulting migration file instead of being
streamed at arbitrary points.

The reasons why we'd want such behavior are:

 - The resulting file will have a bounded size, since pages which are
   dirtied multiple times will always go to a fixed location in the
   file, rather than constantly being added to a sequential
   stream. This eliminates cases where a VM with, say, 1G of RAM can
   result in a migration file that's 10s of GBs, provided that the
   workload constantly redirties memory.

 - It paves the way to implement O_DIRECT-enabled save/restore of the
   migration stream as the pages are ensured to be written at aligned
   offsets.

 - It allows the usage of multifd so we can write RAM pages to the
   migration file in parallel.

For now, enabling the capability has no effect. The next couple of
patches implement the core functionality.

af6e4e0a22 contrib/plugins: extend execlog to track register changes
With the new plugin register API we can now track changes to register
values. Currently the implementation is fairly dumb which will slow
down if a large number of register values are being tracked. This
could be improved by only instrumenting instructions which mention
registers we are interested in tracking.

Example usage:

  ./qemu-aarch64 -D plugin.log -d plugin \
     -cpu max,sve256=on \
     -plugin contrib/plugins/libexeclog.so,reg=sp,reg=z\* \
     ./tests/tcg/aarch64-linux-user/sha512-sve

will display in the execlog any changes to the stack pointer (sp) and
the SVE Z registers.

As testing registers every instruction will be quite a heavy operation
there is an additional flag which attempts to optimise the register
tracking by only instrumenting instructions which are likely to change
its value. This relies on the QEMU disassembler showing up the register
names in disassembly so is an explicit opt-in.

e54c24339f include/qom/object.h: New OBJECT_DEFINE_SIMPLE_TYPE{, _WITH_INTERFACES} macros
We have an OBJECT_DEFINE_TYPE_EXTENDED macro, plus several variations
on it, which emits the boilerplate for the TypeInfo and ensures it is
registered with the type system.  However, all the existing macros
insist that the type being defined has its own FooClass struct, so
they aren't useful for the common case of a simple leaf class which
doesn't have any new methods or any other need for its own class
struct (that is, for the kind of type that OBJECT_DECLARE_SIMPLE_TYPE
declares).

Pull the actual implementation of OBJECT_DEFINE_TYPE_EXTENDED out
into a new DO_OBJECT_DEFINE_TYPE_EXTENDED which parameterizes the
value we use for the class_size field.  This lets us add a new
OBJECT_DEFINE_SIMPLE_TYPE which does the same job as the various
existing OBJECT_DEFINE_*_TYPE_* family macros for this kind of simple
type, and the variant OBJECT_DEFINE_SIMPLE_TYPE_WITH_INTERFACES for
when the type will implement some interfaces.

e5f1500144 tests/avocado: mark boot_linux.py long runtime instead of flaky
The ppc64 and s390x tests were first marked skipIf GITLAB_CI by commit
c0c8687ef0 ("tests/avocado: disable BootLinuxPPC64 test in CI"), and
commit 0f26d94ec9 ("tests/acceptance: skip s390x_ccw_vrtio_tcg on
GitLab") due to being very heavy-weight for gitlab CI.

Commit 9b45cc9931 ("docs/devel: rationalise unstable gitlab tests under
FLAKY_TESTS") changed this to being flaky but it isn't really, it just
had a long runtime.

So take the SPEED=slow variable from qtests and introduce it to avocado,
and make these tests require it.

f165cdf102 exec/ioport: Add portio_list_set_enabled()
Some SuperI/O devices such as the VIA south bridges or the PC87312 controller
allow to enable or disable their SuperI/O functions. Add a convenience function
for implementing this in the VIA south bridges.

The naming of the functions is inspired by its memory_region_set_enabled()
pendant.

ad2b652341 exec/ioport: Add portio_list_set_address()
Some SuperI/O devices such as the VIA south bridges or the PC87312 controller
are able to relocate their SuperI/O functions. Add a convenience function for
implementing this in the VIA south bridges.

This convenience function relies on previous simplifications in exec/ioport
which avoids some duplicate synchronization of I/O port base addresses. The
naming of the function is inspired by its memory_region_set_address() pendant.

0cec50119f qapi: Require member documentation (with loophole)
The QAPI generator forces you to document your stuff.  Except for
command arguments, event data, and members of enum and object types:
these the generator silently "documents" as "Not documented".

We can't require proper documentation there without first fixing all
the offenders.  We've always had too many offenders to pull that off.
Right now, we have more than 500.  Worse, we seem to fix old ones no
faster than we add new ones: in the past year, we fixed 22 ones, but
added 26 new ones.

To help arrest the backsliding, make missing documentation an error
unless the command, type, or event is in listed in new pragma
documentation-exceptions.

List all the current offenders: 117 commands and types in qapi/, and 9
in qga/.

1eeb432a95 doc/sphinx/hxtool.py: add optional label argument to SRST directive
We can't just embed labels directly into files like qemu-options.hx which
are included from multiple top-level rST files, because Sphinx sees the
labels as duplicate: https://github.com/sphinx-doc/sphinx/issues/9707

So add an optional argument to the SRST directive which causes a label
of the form '.. _DOCNAME-HXFILE-LABEL:' to be emitted, where 'DOCNAME'
is the name of the top level rST file, 'HXFILE' is the filename of the
.hx file, and 'LABEL' is the text provided within the 'SRST()' directive.
Using the DOCNAME of the top-level rST document means that it is unique
even when the .hx file is included from two different documents, as is
the case for qemu-options.hx

Now where the Xen PV documentation refers to the documentation for the
-initrd command line option, it can emit a link directly to it as
'<system/invocation-qemu-options-initrd>'.

We don't even have somewhere in the developer docs where we

Add a new files docs/devel/docs.rst which can be a place to
document how our docs build process works. For the moment,
put in only a brief introductory paragraph and the documentation
of the .hx files. We could later add to this file by for
example describing how the QAPI-schema-to-docs process works,
or anything else that developers might need to know about
how to add documentation.

Make the .hx files refer to this doc file, and clean
up their header comments to be more accurate for the
usage in each file and less cut-n-pasted.

d0cda6f461 configure, meson: rename targetos to host_os
This variable is about the host OS, not the target.  It is used a lot
more since the Meson conversion, but the original sin dates back to 2003.
Time to fix it.

0d66549cf5 meson: remove CONFIG_ALL
CONFIG_ALL is tricky to use and was ported over to Meson from the
recursive processing of Makefile variables.  Meson sourcesets
however have all_sources() and all_dependencies() methods that
remove the need for it.
