[PATCH v2 17/30] qapi/migration.json: Replace _this_ with *this*

[Peter Maydell]

The MigrationInfo::setup-time documentation is the only place where
we use _this_ inline markup for emphasis, commonly rendered in
italics.  rST doesn't recognize that markup and emits literal
underscores.

Switch to *this* instead.  Changes markup to strong emphasis with
Texinfo, commonly rendered as bold.  With rST, it will go right back
to emphasis / italics.

rST also uses **this** for strong (commonly rendered bold) where
Texinfo uses *this*. We have one place in the doc comments
which uses strong/bold markup, in qapi/introspect.json:
    Note: the QAPI schema is also used to help define *internal*

When we switch to rST that will be rendered as emphasis / italics.
Markus (who wrote that) thinks that using emphasis / italics
there is an improvement, so we leave that markup alone.
