dbaaf597ff savegame ex.: revamp the way print() works
Basically, instead of re-creating QTextStreams all the time, create it
once, in main(), and then pass it to print() alongside the int
indentation.

Also fix a hard-coded indentation value that should have been relative
to the caller's indentation level.

7eafdf4c81 savegame ex.: revamp the way we (de)serialize JSON
JSON, unlike, say, QDataStream, allows building up objects independent
of some central object, and combining them into a QJsonDocument
later. This suggests returning QJsonObjects from a toJson() const
method instead of having the caller supply a QJsonObject. Doing it
this way enables transparent move semantics to kick in, too.

For deserialization, use a fromJson() named constructor for value-like
classes (where identity doesn't matter, only equality). Keep using
read(), too, and add a note to explain when to use which form.

Also, avoid the triple lookup from

   if (json.contains("key") && json["key"].isSoughtType())
      mFoo = json["key"].toSoughtType();

by using C++17 if-with-initializer and showing the trick with
Undefined never being of isSoughtType():

   if (const QJsonValue v = json["key"]; v.isSoughtType())
      mFoo = v.toSoughtType();

Adjust the discussion to match the new code, up the copyright years
and rename some qdoc snippet markers from nondescript [0]/[1] to
[toJson]/[fromJson].

a6b697ca13 Create corelib/serialization and move existing file formats into it
This is in preparation to adding CBOR support. We don't need yet another
dir for CBOR and placing it in src/corelib/json is just wrong.
