[PATCH 00/10] qapi: convert simple data struct/alternate intro sections

[PATCH 00/10] qapi: convert simple data struct/alternate intro sections

[John Snow]

Hello, this work converts "simple" intro sections for data struct
definitions (and one alternate) in the QAPI schema to use the new
syntax. This is part of our ongoing effort to add the mythical
"inliner" to our generated QMP documentation.

"simple" here is a non-technical distinction that means a single
paragraph of text followed by an existing section boundary that
naturally already delineates what comprises the intro.
(This is about 25% of the remaining conversions.)

"data struct" is another non-technical distinction that means a QAPI
struct that is not used as a branch, argument definition, or the basis
of another struct. In effect, it is only "data" and as a result, is
not *currently* a candidate to be inlined into any other definition.

Documentation that is to be "inlined"-- to be written into another
definition's documentation-- needs to ensure that the documentation
written in the "intro" segment is not crucial to understanding the
behavior of the individual members. The "intro" does not get inlined,
but the rest of the documentation does. These "data structs" as
isolated in this series currently are not eligible to be inlined. As
such, the precise distinction between intro and details for these
definitions is not presently as crucial - however, these structs may
become inlined in the future, so a closer eye is still warranted.

If you are a non-QAPI maintainer who has been CC'd on this series, you
may wish to review what information is being counted as the "intro"
(The indented paragraph) and keep in mind that in the future, this
text may not be visible to the end-user reading our QMP documentation
if this structure is utilized as the 'base' for another struct, used
as the arguments for a command or event, or used as branch of a
union. This series keeps it pretty simple, and every conversion herein
is being codified as "the intro", i.e. "not crucial to understanding
the behavior of the members of this struct".
