[PULL 29/33] migration: Replace migration's JSON writer by the general o


From: Markus Armbruster
Subject: [PULL 29/33] migration: Replace migration's JSON writer by the general one
Date: Sat, 19 Dec 2020 11:55:28 +0100

Commit 8118f0950f "migration: Append JSON description of migration
stream" needs a JSON writer.  The existing qobject_to_json() wasn't a
good fit, because it requires building a QObject to convert.  Instead,
migration got its very own JSON writer, in commit 190c882ce2 "QJSON:
Add JSON writer".  It tacitly limits numbers to int64_t, and strings
contents to characters that don't need escaping, unlike
qobject_to_json().

The previous commit factored the JSON writer out of qobject_to_json().
Replace migration's JSON writer by it.
