We have about 30 instances of the typo/variant spelling 'writeable',
and over 500 of the more common 'writable'. Standardize on the
latter.
Change produced with:
sed -i -e 's/\([Ww][Rr][Ii][Tt]\)[Ee]\([Aa][Bb][Ll][Ee]\)/\1\2/g' $(git grep -il writeable)
and then hand-undoing the instance in linux-headers/linux/kvm.h.
Most of these changes are in comments or documentation; the
exceptions are:
* a local variable in accel/hvf/hvf-accel-ops.c
* a local variable in accel/kvm/kvm-all.c
* the PMCR_WRITABLE_MASK macro in target/arm/internals.h
* the EPT_VIOLATION_GPA_WRITABLE macro in target/i386/hvf/vmcs.h
(which is never used anywhere)

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.

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.

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.

When starting an L2 KVM guest with `ic-mode=dual,kernel-irqchip=on`,
QEMU fails with:
KVM is too old to support ic-mode=dual,kernel-irqchip=on
This error message was introduced to detect older KVM versions that
didn't allow destruction and re-creation of the XICS KVM device that
we do at reboot. But it is actually the same issue that we get with
nested guests : when running under pseries, KVM currently provides
a genuine XICS device (not the XICS-on-XIVE device that we get
under powernv) which doesn't support destruction/re-creation.
This will eventually be fixed in KVM but in the meantime, update
the error message and documentation to mention the nested case.
While here, mention that in "No XIVE support in KVM" section that
this can also happen with "guest OSes supporting XIVE" since
we check this at init time before starting the guest.
