Minor refactoring and style fixups:

Minor refactoring and style fixups:
- private lineLayoutsList can be a primitive array
- eliminate some stray hungarians (inconsistent btw: iFirstIndex, but nEliminableLines...)
- inverted principal loop in createLineBreaks(), to make debugging less confusing (and preparation for partial fix of Bug 38264)
- compacted some boolean expressions ( (x ? true : false) -> plain x )
- removed some commented code
- extracted some code into processUpdates; findHyphenationPoints was getting too long
- minor javadoc fixups
