The address_space_rw() function allows either reads or writes
depending on the is_write argument passed to it; this is useful
when the direction of the access is determined programmatically
(as for instance when handling the KVM_EXIT_MMIO exit reason).
Under the hood it just calls either address_space_write() or
address_space_read_full().
We also use it a lot with a constant is_write argument, though,
which has two issues:
* when reading "address_space_rw(..., 1)" this is less
immediately clear to the reader as being a write than
"address_space_write(...)"
* calling address_space_rw() bypasses the optimization
in address_space_read() that fast-paths reads of a
fixed length

A handful of QAPI doc comments include lines like
"ppcemb: dropped in 3.1". The doc comment parser will just
put these into whatever the preceding section was; sometimes
that's "Notes", and sometimes it's some random other section,
as with "NetClientDriver" where the "'dump': dropped in 2.12"
line ends up in the "Since:" section.
This tends to render wrongly, more so in the upcoming rST
generator, but sometimes even in the Texinfo, as in the case
of QKeyCode:
ac_bookmarks
since 2.10 altgr, altgr_r: dropped in 2.10
Since commit 3264ffced3 (v4.2.0), we have a better place to tell
users about deprecated and deleted functionality --
qemu-deprecated.texi. These "dropped in" remarks all predate it, and
other feature drops of that vintage are not documented anywhere, so
moving these to qemu-deprecated.texi makes little sense. Drop them
instead.

The MigrationInfo::setup-time documentation is the only place where we
use _this_ inline markup for emphasis, commonly rendered in italics.
We would like to switch the doc comments to rST format, but rST
doesn't recognize that markup and emits literal underscores.
Switch to *this* instead. Changes markup to strong emphasis with
Texinfo, commonly rendered as bold. With rST, it will go right back
to emphasis / italics.
rST also uses **this** for strong (commonly rendered bold) where
Texinfo uses *this*. We have one place in the doc comments
which uses strong/bold markup, in qapi/introspect.json:
Note: the QAPI schema is also used to help define *internal*
When we switch to rST that will be rendered as emphasis / italics.
Markus (who wrote that) thinks that using emphasis / italics
there is an improvement, so we leave that markup alone.

chunk of text ("The @device...take precedence") which is intended
to be the main body text describing the event. However it has
been placed after the arguments and Returns: section, which
means that the parser actually thinks that this text is

This commit is a purely whitespace change, and it does not alter the

The ascii-art graph in the BlockLatencyHistogramInfo documentation
doesn't render correctly, because the whitespace is collapsed.
Use the '|' format that emits a literal 'example' block so the graph
is displayed correctly.
Strictly the Texinfo generated is still wrong because each line
goes into its own @example environment, but it renders better
than what we had before.
Fixing this rendering is a necessary prerequisite for the upcoming rST
generator, which otherwise complains about the inconsistent
indentation in the ascii-art graph.

We would like to switch the doc comments to rST format, and rST
requires a blank line before the start of a bulleted or enumerated
list. Two places in qapi-schema.json were missing this blank line.
Some places were using an indented line as a sort of single-item
bulleted list, which in the Texinfo output comes out all run
onto a single line; use a real bulleted list instead.
Some places unnecessarily indented lists, which confuses rST.
guest-fstrim:minimum's documentation was indented the
right amount to share a line with @minimum, but wasn't
actually doing so.
The indent on the bulleted list in the guest-set-vcpus
Returns section meant rST misindented it.
Changes to the generated Texinfo are very minor (the new
bulleted lists, and a few extra blank lines).
