docs: Split out sections for the manpage into .rst.inc files

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.

qemu-options.hx: Fix up the autogenerated rST

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.

docs: Roll -prom-env and -g target-specific info into qemu-options.hx

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SPARC also has a bit of text about the -M option which is out of
date and provides no useful information over the generic documentation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.

docs: Roll semihosting option information into qemu-options.hx

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.

doc/scripts/hxtool.py: Strip trailing ':' from DEFHEADING/ARCHHEADING

In hxtool files, section headings defined with the DEFHEADING
and ARCHHEADING macros have a trailing ':'
DEFHEADING(Standard options:)

This is for the benefit of the --help output. For consistency
with the rest of the rST documentation, strip any trailing ':'
when we construct headings with the Sphinx hxtool extension.
This makes the table of contents look neater.

This only affects generation of documentation from qemu-options.hx,
which we will start doing in a later commit.

Note that most of the SRST fragments are 2-space indented so that the

In addition, the following changes were made manually:

- target-i386.rst and target-mips.rst: replace CPU model documentation with
an include directive

- monitor.rst: replace the command section with a comment

- images.rst: add toctree

- target-arm.rst: Replace use of :math: (which Sphinx complains
about) with :sup:, and hide it behind |I2C| and |I2C| substitutions.

docs/system: Convert qemu-cpu-models.texi to rST

This doc was originally written by Daniel P. Berrangé
<berrange@redhat.com>, introduced via commit[1]: 2544e9e4aa (docs: add
guidance on configuring CPU models for x86, 2018-06-27).

In this patch:

- 1-1 conversion of Texinfo to rST, besides a couple of minor
tweaks that are too trivial to mention. (Thanks to Stephen
Finucane on IRC for the suggestion to use rST "definition lists"
instead of bullets in some places.)

Further modifications will be done via a separate patch.

- rST and related infra changes: manual page generation, Makefile
fixes, clean up references to qemu-cpu-models.texi, update year in
the copyright notice, etc.

[1] https://git.qemu.org/?p=qemu.git;a=commit;h=2544e9e4aa

As part of the conversion, we use a more generic 'author' attribution
for the manpage than we previously had, as agreed with the original
author Dan Berrange.

docs: Create defs.rst.inc as a place to define substitutions

Rather than accumulating generally useful rST substitution
definitions in individual rST files, create a defs.rst.inc where we

from qemu-block-drivers.rst.

Add a comment noting a pitfall where putting literal markup in the
definition of |qemu_system| makes it misrender manpage output; this
means the point-of-use must handle the literal markup (which is
almost always done by having it inside a parsed-literal block).

qemu-doc: Remove the "CPU emulation" part of the "Implementation notes"

The "CPU emulation" part of the "Implementation notes" in
qemu-tech.texi looks like it is documenting what features of various
CPUs we do or don't emulate. However:
* it covers only six of our 21 guest architectures
* the last time anybody updated it for actual content was in
2011/2012 for Xtensa; the content for the other five
architectures is even older, being from 2008 or before!

What we have is out of date, misleading and incomplete.
Just delete this part of the document rather than trying to
convert it to rST.

(It would be nice eventually to have documentation of the
scope and limitations of our emulation; but we will want to
separate out the generic "system emulation" information from
the parts that are specific to linux-user anyway, as they will
be in different manuals.)
