[PATCH v2 8/9] qapi: convert "Example" sections with longer prose

[John Snow]

These examples require longer explanations or have explanations that
require markup to look reasonable when rendered and so use the longer
form of the ".. qmp-example::" directive.

By using the :annotated: option, the content in the example block is
assumed *not* to be a code block literal and is instead parsed as normal
rST - with the exception that any code literal blocks after `::` will
assumed to be a QMP code literal block.

Note: There's one title-less conversion in this patch that comes along
for the ride because it's part of a larger "Examples" block that was
better to convert all at once.

See commit-5: "docs/qapidoc: create qmp-example directive", for a
              detailed explanation of this custom directive syntax.

See commit+1: "qapi: remove "Example" doc section" for a detailed
              explanation of why.
