QTextLayout: keep strong reference on font engine in a layout loop
This is speculative fix for the crashes in QTextLine::layout_helper()
we're observing on users side.
The possible reason is in that fontEngine and previousGlyphFontEngine,
which are stored in LBH, became invalid during the layout cycle
(destroyed by trimming font cache?).
To prevent this we need to handle font engine's ref-counter
gracefully, so just wrap them into QExplicitlySharedDataPointer.
As a drive-by change, use in-class initialization for LBH members.
