9fd2e78b96 docs: xsl: Unify stylability of main container element
page.xsl was adding '<div id="content">' wrapper for the content picked
up from the <body> element from the original input file. Optionally
class="$DOCNAME" was added for some documents taken from <body>.

Since docs generated from RST by docutils have a '<div class='document'
id='$DOCNAME>' we actually don't need an extra wrapper for them.

Additionally if we standardize on one of them we can use the same styles
for both. I've picked the latter because it makes more sense to use the
document name as 'id'.

This patch:
1) Modifies the XSL trasformation to add the wrapper only if it's not
   present.

2) Modifies the XSL transformation to use 'id' for document name and
   class='document' for the wrapper element.

3) Changes docs.html/index.html/hvsupport.html to use 'id' instead of
   'class' for document name.

4) Modifies the main stylesheet to keep styling the elements properly

With the move to GitLab CI one of the things we miss from Jenkins is a

very simple replacement that uses badges for CI pipeline status.

A CSS tweak is needed because RST->HTML adds redundant <p> tags inside

40780d1a4c docs: introduce rst2man as a mandatory tool for building docs
The rst2man tool is provided by python docutils, and as the name
suggests, it converts RST documents into man pages.

The intention is that our current POD docs will be converted to
RST format, allowing one more use of Perl to be eliminated from
libvirt.

The manual pages will now all be kept in the docs/manpages/ directory,
which enables us to include the man pages in the published website.
This is good for people searching for libvirt man pages online as it
makes it more likely google will send them to the libvirt.org instead
of some random third party man page site with outdated content.

252958ee16 backup: Document new XML for backups
Prepare for new backup APIs by describing the XML that will represent
a backup.  The XML resembles snapshots and checkpoints in being able
to select actions for a set of disks, but has other differences.  It
can support both push model (the hypervisor does the backup directly
into the destination file) and pull model (the hypervisor exposes an
access port for a third party to grab what is necessary).  Add
testsuite coverage for some minimal uses of the XML.

The <disk> element within <domainbackup> tries to model the same
elements as a <disk> under <domain>, but sharing the RNG grammar
proved to be hairy. That is in part because while <domain> use
<source> to describe a host resource in use by the guest, a backup job
is using a host resource that is not visible to the guest: a push
backup action is instead describing a <target> (which ultimately could
be a remote network resource, but for simplicity the RNG just
validates a local file for now), and a pull backup action is instead
describing a temporary local file <scratch> (which probably should not
be a remote resource).  A future refactoring may thus introduce some
way to parameterize RNG to accept <disk type='FOO'>...</disk> so that
the name of the subelement can be <source> for domain, or <target> or
<scratch> as needed for backups. Future patches may improve this area
of code.

Most importantly we document the required heading markup so that we get
consistency across the docs. Also mention that docs should have a table
of contents if they have headings & are likely longer than one page of
text.

The 3-space indent rule may sound wierd, but that's what python has
recommended and thus what tools like pandoc emit. Rather than try to
reindent things to 4-space, just accept this RST norm.

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)

The OOM handling requires special build time options which we never

typically require manual inspection of the results to weed out false
positives.

Since there was previous agreement to switch to abort on OOM in libvirt
code, there's no point continuing to keep the unused OOM testing code.

0d44788fc3 backup: Introduce virDomainCheckpoint APIs
Introduce a bunch of new public APIs related to backup checkpoints.
Checkpoints are modeled heavily after virDomainSnapshotPtr (both
represent a point in time of the guest), although a snapshot exists
with the intent of rolling back to that state, while a checkpoint
exists to make it possible to create an incremental backup at a later
time.  We may have a future hypervisor that can completely manage
checkpoints without libvirt metadata, but the first two planned
hypervisors (qemu and test) both always use libvirt for tracking
metadata relations between checkpoints, so for now, I've deferred
the counterpart of virDomainSnapshotHasMetadata for a separate
API addition at a later date if there is ever a need for it.

Note that until we allow snapshots and checkpoints to exist
simultaneously on the same domain (although the actual prevention of
this will be in a separate patch for the sake of an easier revert down
the road), that it is not possible to branch out to create more than
one checkpoint child to a given parent, although it may become
possible later when we revert to a snapshot that coincides with a
checkpoint.  This also means that for now, the decision of which
checkpoint becomes the parent of a newly created one is the only
checkpoint with no child (so while there are APIs for dealing with a
current snapshot, we do not need those for checkpoints).  We may end
up exposing a notion of a current checkpoint later, but it's easier to
add stuff when proven needed than to blindly support it now and wish
we hadn't exposed it.

The following map shows the API relations to snapshots, with new APIs
on the right:

Operate on a domain object to create/redefine a child:
virDomainSnapshotCreateXML          virDomainCheckpointCreateXML

Operate on a child object for lifetime management:
virDomainSnapshotDelete             virDomainCheckpointDelete
virDomainSnapshotFree               virDomainCheckpointFree
virDomainSnapshotRef                virDomainCheckpointRef

Operate on a child object to learn more about it:
virDomainSnapshotGetXMLDesc         virDomainCheckpointGetXMLDesc
virDomainSnapshotGetConnect         virDomainCheckpointGetConnect
virDomainSnapshotGetDomain          virDomainCheckpointGetDomain
virDomainSnapshotGetName            virDomainCheckpiontGetName
virDomainSnapshotGetParent          virDomainCheckpiontGetParent
virDomainSnapshotHasMetadata        (deferred for later)
virDomainSnapshotIsCurrent          (no counterpart, see note above)

Operate on a domain object to list all children:
virDomainSnapshotNum                (no counterparts, these are the old
virDomainSnapshotListNames           racy interfaces)
virDomainSnapshotListAllSnapshots   virDomainListAllCheckpoints

Operate on a child object to list descendents:
virDomainSnapshotNumChildren        (no counterparts, these are the old
virDomainSnapshotListChildrenNames   racy interfaces)
virDomainSnapshotListAllChildren    virDomainCheckpointListAllChildren

Operate on a domain to locate a particular child:
virDomainSnapshotLookupByName       virDomainCheckpointLookupByName
virDomainSnapshotCurrent            (no counterpart, see note above)
virDomainHasCurrentSnapshot         (no counterpart, old racy interface)

Operate on a snapshot to roll back to earlier state:
virDomainSnapshotRevert             (no counterpart, instead checkpoints
                                     are used in incremental backups via
				     XML to virDomainBackupBegin)

Add testsuite coverage for some minimal uses of the XML (bare minimum,
the sample from html, and a full dumpxml, and some counter-examples
that should fail schema validation). Although use of the REDEFINE flag
will require the <domain> subelement to be present, it is easier for
most of the tests to provide counterpart output produced with the
NO_DOMAIN flag (particularly since synthesizing a valid <domain>
during testing is not trivial).

with old libvirt.so, b) there are both rust + go impls that are written
against the RPC protocol already.

5a26d1ce12 Point to the new libvirt-go bindings
The github.com/rgbkrk/libvirt-go bindings were the most complete
bindings historically, but their API coverage stops at 1.2.4,
with exception of a couple of newer APIs.

The new bindings at http://libvirt.org/git/?p=libvirt-go.git;a=log
how have (almost[1]) 100% API coverage all the way to 2.5.0. They also
expose the APIs in a way that allows for much stronger go type
checking by the compiler, and expose typed parameters as explicit
structs. Finally the bindings are able to conditionally compile against
any libvirt version 1.2.0 -> 2.5.0 without use of go build tags.

Change the docs to point to these new bindings, since they'll be
a better bet for users long term.

[1] virEvent & virStream callbacks are still TODO to be fixed
    real soon.
