The QTextLayout::FormatRange is larger than void* and thus should not be held in
QList. Use a QVector instead.
Other parts of Qt already hold FormatRanges in QVectors, so this also makes
handling FormatRanges more consistent.
To avoid ugly names for the getter which doesn't overload on return type alone),
rename the set of function to format (from additionalFormats).
[ChangeLog][QtGui][QTextLayout] Added QVector-based alternatives setFormat(),
format(), and clearFormat() to setAdditionalFormats(), additionalFormats(),
and clearAdditionalFormats(), resp.
