8215da927a docs: adapt filling of <head> section for rst2html output
The HTML from rst2html doesn't have <h1> immediately under the <body>
tag, instead there is at least one <div> in between.

There are also many things added in the <head> section that we don't
want to have copied over, since our templating system already adds
suitable <head> elements.

We only need to copy the <script> to make index.html work.

c7f75bf04d docs: introduce rst2html as a mandatory tool for building docs
The rst2html tool is provided by python docutils, and as the name
suggests, it converts RST documents into HTML.

Basic rules are added for integrating RST docs into the website
build process.

This enables us to start writing docs on our website in RST format
instead of HTML, without changing the rest of our website templating
system away from XSLT yet.

bfe9f25b49 docs: move docs about remote driver URIs into URI docs
The docs about remote URIs in uri.html are somewhat sparse with the full
docs being in remote.html. Move all the URI content from remote.html
into uri.html so the user only needs to look in one place for URI info.

8d9ca128f1 docs: don't run xmllint when generating API HTML files

to validate the correctness. Since

  Author: Daniel P. Berrangé <berrange@redhat.com>
  Date:   Wed Nov 20 14:49:26 2019 +0000

    docs: generate API reference pages for admin, qemu & lxc libraries

we have many rules generating files into docs/html/. The xmllint
calls for each rule are picking up files which are part-generated by
other parallel build rules resulting in transient errors like:

  GEN      html/index.html
  GEN      html/index-admin.html
  GEN      html/index-qemu.html
  GEN      html/index-lxc.html
  GEN      hvsupport.html.in
html/index-lxc.html:1: parser error : Document is empty

^
make[4]: *** [Makefile:2407: html/index-qemu.html] Error 1

The easiest solution is to move the xmllint rules to the 'make check'
phase of the build.

supported and <backingStore> is present on input.

9b80e0c12a util: drop support for stack traces with logging
The log filters have supported the use of a "+" before the source match
string to request that a stack trace be emitted for every log message:

  commit 548563956e
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Wed May 9 15:18:56 2012 +0100

    Allow stack traces to be included with log messages

    Sometimes it is useful to see the callpath for log messages.
    This change enhances the log filter syntax so that stack traces
    can be show by setting '1:+NAME' instead of '1:NAME'.

With the huge & ever increasing number of logging statements per file,
this will be incredibly verbose and have a major performance penalty.
This makes the feature impractical to use widely and as such it is not
worth the code maint cost.

Removing this seldom used feature allows us to drop the 'execinfo'
module in gnulib which provides the backtrace() function which doesn't
exist on non-Linux.

Users who want to get stack traces of parts of libvirt can use GDB,
or systemtap for live tracing with minimal perf impact.

Libvirt currently uses the VIR_AUTOUNREF macro for auto cleanup of
virObject instances. GLib approaches things differently with GObject,
reusing their g_autoptr() concept.

This introduces support for g_autoptr() with virObject, to facilitate
the conversion to GObject.

Only virObject classes which are currently used with VIR_AUTOREF are
updated. Any others should be converted to GObject before introducing
use of autocleanup.

As a result it is now possible to use g_autoptr/VIR_AUTOPTR, and
g_auto/VIR_AUTOCLEAN, g_autofree/VIR_AUTOFREE interchangably, regardless
of which macros were used to declare the cleanup types.

Within the scope of any single method, code must remain consistent
using either GLib or Libvirt macros, never mixing both. New code
must preferentially use the GLib macros, and old code will be
converted incrementally.

cfbe9f1201 build: link to glib library
Add the main glib.h to internal.h so that all common code can use it.

Historically glib allowed applications to register an alternative
memory allocator, so mixing g_malloc/g_free with malloc/free was not
safe.

This was feature was dropped in 2.46.0 with:

      commit 3be6ed60aa58095691bd697344765e715a327fc1
      Author: Alexander Larsson <alexl@redhat.com>
      Date:   Sat Jun 27 18:38:42 2015 +0200

        Deprecate and drop support for memory vtables

Applications are still encourged to match g_malloc/g_free, but it is no
longer a mandatory requirement for correctness, just stylistic. This is
explicitly clarified in

    commit 1f24b36607bf708f037396014b2cdbc08d67b275
    Author: Daniel P. Berrangé <berrange@redhat.com>
    Date:   Thu Sep 5 14:37:54 2019 +0100

        gmem: clarify that g_malloc always uses the system allocator

Applications can still use custom allocators in general, but they must
do this by linking to a library that replaces the core malloc/free
implemenentation entirely, instead of via a glib specific call.

This means that libvirt does not need to be concerned about use of
g_malloc/g_free causing an ABI change in the public libary, and can
avoid memory copying when talking to external libraries.

This patch probes for glib, which provides the foundation layer with
a collection of data structures, helper APIs, and platform portability
logic.

Later patches will introduce linkage to gobject which provides the
object type system, built on glib, and gio which providing objects
for various interesting tasks, most notably including DBus client
and server support and portable sockets APIs, but much more too.

557ac8cbf5 docs: attempt to document the general libvirt dev strategy
There are various ideas / plans floating around for future libvirt work,
some of which is actively in progress. Historically we've never captured
this kind of information anywhere, except in mailing list discussions.
In particular guidelines in hacking.html.in don't appear until a policy
is actively applied.

This patch attempts to fill the documentation gap, by creating a new
"strategy" page which outlines the general vision for some notable
future changes. The key thing to note is that none of the stuff on this
page is guaranteed, plans may change as new information arises. IOW this
is a "best guess" as to the desired future.

This doc has focused on three areas, related to the topic of language
usage / consolidation

 - Use of non-C languages for the library, daemons or helper tools
 - Replacement of autotools with meson
 - Use of RST and Sphinx for documentation (website + man pages)
