This change includes debugging code to warn for negative scroll/ 
maxscroll values.  At least for the scrollinputtext (updated to use  
the undocumented scrollheight attr so it works) maxscroll never  
matches the value in the sprite...  I think it's fine to doc  
scrollheight and use it, but maxscroll should be correct for backward  
compatibility.  I still think my previous change is correct.

Summary: [UPDATE 5] Implement LFC end of kernel scrolling API

Bugs Fixed: LPP-6580  scrolledittext doesn't work in 4.1 (partial)

Technical Reviewer: ptw (pending)
QA Reviewer: hminsky (pending)

Details:
     LzSprite.*, LaszloView, LaszloCanvas: Add linescrolling
     capability, unify capabilities as a sprite instance var.

     swf/LzTextSprite.as: Turn on warnUndefinedReferences so we can
     debug this.  Stop making all sorts of undefined references.
     Actually compute `lineheight`.  Use that to implement the
     pixel/line kernel API.  Convert __updatefieldsize to use the new
     scrollevent kernel API.

     swf9/LzTextSprite: Add primitive version of setX/YScroll, add  
callbacks
     to mirror swf8 version

     swf9/LzInputTextSprite: Elimanate duplicate scroll attribute

     LzInputText: Set tsprite in __makeSprite

     LzText: Implement new kernel scrolling API.  Cache tsprite for
     efficiency.

     newcontent: Silence warnings.

     scrolledittext: Update to eliminate warnings, use build-in  
lineheight

     newvscrollbar-test/scrolledittext-test: Improve tests

     basescrollbar.lzx - Don't update scroll pos unless it's needed

Tests:
     Compiles in swf9, smokecheck in 3 runtimes, component debugger in
     swf8/9, component sampler in 3 runtimes.  scrolledittext-test.lzx  
runs
     consistently across swf8/9.
