The docs illustration for the <os> schema contains a mixture of
incompatible configuration options. This is rather confusing and
misleading to users. Splitting the illustration into four separate
examples clarifies the situation.

'virDomainSnapshotRedefinePrep' does everything needed for a redefine
when the snapshot exists but not when we are defining metadata for a new
snapshot. This gives us weird semantics.

into a new helper 'virDomainSnapshotReplaceDef' and refactor all

It is not expected that a function with 'Validate' in the name actually
modifies the validated object, even worse when it even modifies another

Due to historical reasons we allow users to redefine an existing
snapshot without providing the domain definition which would correspond
to it. In such case we'd use the domain definition from the snapshot
that is being redefined.
To prevent callers from doing complex moving of the domain definition
object back and forth between the snapshot definitions we can add an
argument to virDomainSnapshotAlignDisks which will allow us to pass in
the alternate definition if the one from the snapshot is missing.

'require_match' set to true is only needed for internal snapshots taken
by hypervisors (qemu) which don't have a way to control which disks take
part in the snapshot (savevm).
To de-clutter callers we can change the argument to mean 'this code path
requires uniform snapshot for internal snapshots'.
Change the argument and fix the callers. For now all callers pass 'true'
but any new hypervisor or even usage in qemu is not going to share the
limitation.

External snapshot with memory is created without using the

configuring the XML. When redefining the code should be checking the

Commit f4aae9726d factored out the snapshot redefinition code into a
separate function, but didn't account for the fact that the code is
consuming the reference to the snapshot definition and by moving the
code away the caller (qemuSnapshotCreateXML) now frees the definition
which didn't happen before as we cleared the pointer.
Fix it by increasing the reference locally. Later patches will refactor
the code so that it's more obvious what's happening.

Our approach to snapshots without metadata was to insert them to the
snapshot list and then later remove them from the list when the flag is
present.
This quirky logic was broken in a recent refactor of the snapshot code
causing that the snapshot stayed inserted in the snapshot list.
Recent refactor of the snapshot code didn't faithfully relocate this
logic to the new function.
Rather than attempting to restore the quirky logic of adding and then
removing the object, don't add the snapshot into the list at all when
the user doesn't want metadata.
We achieve this by creating a temporary 'virDomainMomentObj' wrapper
which is not inserted into the list and using that instead of calling
virDomainSnapshotAssignDef.
