b09d51c909 Report stringified errno in VFIO related errors
In a few places we report errno formatted as a negative integer.
This is not as user friendly as it can be. Use strerror() and/or
error_setg_errno() instead.

7d3f505359 monitor: Move qmp_query_qmp_schema to qmp-cmds-control.c
monitor/misc.c contains code that works only in the system emulator, so
it can't be linked to tools like a storage daemon. In order to make
schema introspection available for tools, move the function to
monitor/qmp-cmds-control.c, which can be linked into the storage daemon.

misc.json contains definitions that are related to the system emulator,
so it can't be used for other tools like the storage daemon. This patch
moves basic functionality that is shared between all tools (and mostly
related to the monitor itself) into a new control.json, which could be

bb5ccf225e qapi: Delete all the "foo: dropped in n.n" notes
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.

a660eed482 qapi/migration.json: Replace _this_ with *this*
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.

100cc4fe0f qapi: Add blank lines before bulleted lists
We would like to switch the doc comments to rST format. rST
insists on a blank line before and after a bulleted list, but our
Texinfo doc generator did not. Add some extra blank lines in the doc
comments so they're acceptable rST input.

              If @node is not a valid block device, DeviceNotFound
              If @name is not found, GenericError with an explanation

renders like this:

     Returns: nothing on success If node is not a valid block device,
     DeviceNotFound If name is not found, GenericError with an explanation

because whitespace is not significant.

Use an actual bulleted list, so that the formatting is correct.

449be9df52 qapi/ui.json: Avoid `...' Texinfo style quoting
Avoid Texinfo style quoting with `...', because we would like to
switch the doc comments to rST format, and rST treats it as a syntax
error. Use '...' instead, as we do in other doc comments. This looks
OK in Texinfo, and rST formats it as paired-quotation-marks.

43d7c2d06e qapi/ui.json: Put input-send-event body text in the right place
In the doc comment for input-send-event, there is a multi-line
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
part of the "Returns" section text.

Move the body text up to the top so that the parser correctly
classifies it as body.

26ec4e53f2 qapi: Fix indent level on doc comments in json files
The current doc generation doesn't care much about indentation levels,
but we would like to switch to an rST format, and rST does care about
indentation.

Make the doc comments more strongly consistent about indentation
for multiline constructs like:

@arg: description line 1
      description line 2

Returns: line one
         line 2

so that there is always exactly one space after the colon, and
subsequent lines align with the first.

This commit is a purely whitespace change, and it does not alter the
generated .texi files (because the texi generation code strips away
all the extra whitespace).  This does mean that we end up with some
over-length lines.

Note that when the documentation for an argument fits on a single
line like this:

@arg: one line only

then stray extra spaces after the ':' don't affect the rST output, so
I have not attempted to methodically fix them, though the preference
is a single space here too.

f56275064e qapi: Fix incorrect "Not documented" claims in QMP documentation
Some qapi doc comments have forgotten the ':' after the
@argument, like this:

# @filename         Filename for the new image file
# @size             Size of the virtual disk in bytes

The result is that these are parsed as part of the body
text and appear as a run-on line:
  filename Filename for the new image file size Size of the virtual disk in bytes"
followed by
  filename: string
    Not documented
  size: int
    Not documented

in the 'Members' section.

Correct the formatting.

0a940d66de qapi/block-core.json: Use literal block for ascii art
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.

a7b6e89641 qga/qapi-schema.json: minor format fixups for rST
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).

758b617af8 configure: Check that sphinx-build is using Python 3
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.)

971b2a1e5b RISC-V Patches for the 5.0 Soft Freeze, Part 2
This is a fairly light-weight pull request, but I wanted to send it out to
 avoid the Goldfish stuff getting buried as the next PR should contain the H
 extension implementation.
 
 As far as this PR goes, it contains:
 
 * The addition of syscon device tree nodes for reboot and poweroff, which
   allows Linux to control QEMU without an additional driver.  The existing
   device was already compatible with the syscon interface.
 * A fix to our GDB stub to avoid confusing XLEN and FLEN, specifically useful
   for rv32id-based systems.
 * A device emulation for the Goldfish RTC device, a simple memory-mapped RTC.
 * The addition of the Goldfish RTC device to the RISC-V virt board.
 
 This passes "make check" and boots buildroot for me.

dc7a88d081 target/arm: Implement ARMv8.1-VMID16 extension
The ARMv8.1-VMID16 extension extends the VMID from 8 bits to 16 bits:

 * the ID_AA64MMFR1_EL1.VMIDBits field specifies whether the VMID is
   8 or 16 bits
 * the VMID field in VTTBR_EL2 is extended to 16 bits
 * VTCR_EL2.VS lets the guest specify whether to use the full 16 bits,
   or use the backwards-compatible 8 bits

For QEMU implementing this is trivial:
 * we do not track VMIDs in TLB entries, so we never use the VMID field
 * we treat any write to VTTBR_EL2, not just a change to the VMID field
   bits, as a "possible VMID change" that causes us to throw away TLB
   entries, so that code doesn't need changing
 * we allow the guest to read/write the VTCR_EL2.VS bit already

So all that's missing is the ID register part: report that we support
VMID16 in our 'max' CPU.
