01e449809b *-user: Deprecate and disable -p pagesize
This option controls the host page size.  From the mis-usage in
our own testsuite, this is easily confused with guest page size.

The only thing that occurs when changing the host page size is
that stuff breaks, because one cannot actually change the host
page size.  Therefore reject all but the no-op setting as part
of the deprecation process.

This option has been deprecated before the 8.1 release,

060e0cd751 bsd-user: Add '-one-insn-per-tb' option equivalent to '-singlestep'
The '-singlestep' option is confusing, because it doesn't actually
have anything to do with single-stepping the CPU. What it does do
is force TCG emulation to put one guest instruction in each TB,
which can be useful in some situations.

Create a new command line argument -one-insn-per-tb, so we can
document that -singlestep is just a deprecated synonym for it,
and eventually perhaps drop it.

74154d7e4a linux-user: Remove the deprecated ppc64abi32 target
It's likely broken, and nobody cared for picking it up again
during the deprecation phase, so let's remove this now.

Since this is the last entry in deprecated_targets_list, remove
the related code in the configure script, too.

06905f6402 docs: standardize directory index to --- with overline
Use a standard heading format for the index.rst file in a directory.
Using overlines makes it clear that individual documents can use e.g.
=== for chapter titles and --- for section titles, as suggested in the
Linux kernel guidelines[1].  They could do it anyway, because documents
included in a toctree are parsed separately and therefore are not tied
to the same conventions for headings.  However, keeping some consistency is
useful since sometimes files are included from multiple places.

b4634487c4 docs: Stop calling the top level subsections of our manual 'manuals'
We merged our previous multiple-manual setup into a single Sphinx
manual, but we left some text in the various index.rst lines that
still calls the top level subsections separate 'manuals'.  Update
them to talk about "this section of the manual" instead, and remove
now-obsolete comments about how the index.rst files are the "top
level page for the 'foo' manual".

73e6aec652 sphinx: adopt kernel readthedoc theme
The default "alabaster" sphinx theme has a couple shortcomings:
- the navbar moves along the page
- the search bar is not always at the same place
- it lacks some contrast and colours

The "rtd" theme from readthedocs.org is a popular third party theme used
notably by the kernel, with a custom style sheet. I like it better,
perhaps others do too. It also simplifies the "Edit on Gitlab" links.

Tweak a bit the custom theme to match qemu.org style, use the
QEMU logo, and favicon etc.

5b30c53041 docs/user: Remove outdated 'Quick Start' section
The 'Quick Start' section of the userspace emulator documentation is
very old and outdated. In particular:
 - it suggests running x86-on-x86 emulation, which is the least
   interesting possible use case
 - it recommends that users download tarballs of guest binaries
   from the QEMU web page which we no longer provide there

There's nothing salvageable here; delete it all.

b93f4fbdc4 docs: Build and install all the docs in a single manual
When we first converted our documentation to Sphinx, we split it into
multiple manuals (system, interop, tools, etc), which are all built
separately.  The primary driver for this was wanting to be able to
avoid shipping the 'devel' manual to end-users.  However, this is
working against the grain of the way Sphinx wants to be used and
causes some annoyances:
 * Cross-references between documents become much harder or
   possibly impossible
 * There is no single index to the whole documentation
 * Within one manual there's no links or table-of-contents info
   that lets you easily navigate to the others
 * The devel manual doesn't get published on the QEMU website
   (it would be nice to able to refer to it there)

Merely hiding our developer documentation from end users seems like
it's not enough benefit for these costs.  Combine all the
documentation into a single manual (the same way that the readthedocs
site builds it) and install the whole thing.  The previous manual
divisions remain as the new top level sections in the manual.

 * The per-manual conf.py files are no longer needed
 * The man_pages[] specifications previously in each per-manual
   conf.py move to the top level conf.py
 * docs/meson.build logic is simplified as we now only need to run
   Sphinx once for the HTML and then once for the manpages5B
 * The old index.html.in that produced the top-level page with
   links to each manual is no longer needed

Unfortunately this means that we now have to build the HTML
documentation into docs/manual in the build tree rather than directly
into docs/; otherwise it is too awkward to ensure we install only the
built manual and not also the dependency info, stamp file, etc.  The
manual still ends up in the same place in the final installed
directory, but anybody who was consulting documentation from within
the build tree will have to adjust where they're looking.

6fe6d6c9a9 docs: Be consistent about capitalization of 'Arm'
The company 'Arm' went through a rebranding some years back
involving a recapitalization from 'ARM' to 'Arm'. As a result
our documentation is a bit inconsistent between the two forms.
It's not worth trying to update everywhere in QEMU, but it's
easy enough to make docs/ consistent.

Note that "ARMv8" and similar architecture names, and
older CPU names like "ARM926" still retain all-caps.
