I would appreciate a close review of the small changes to .lzs files.

Summary: Enable -debug options for LFC and applications

New Features:

Bugs Fixed: LPP-6686 (create debug lfc for swf9), LPP-6687 (makes sure lzc works properly for swf 9 w/ and w/out debug)

Release Notes:

Details:
    Creates a LFC9-debug.swc during LFC build.  Uses this when
    lzc is invoked with -g or --options debug=true or
when debug attribute used (<canvas debug="true">) or URL ...&debug=true

    Note: The -g/debug option for swf9 means that:
         a special 'debugSWF9' option is turned on internally - this
         causes -debug=true to be given to the external compiler.
         It also turns *off* the sc compiler's typical actions for
         DEBUG and DEBUG_BACKTRACE (that is, generating inline code to
         support a debugging window in the browser).  So debugging on
         SWF9 means using fdb.

    lfc/build.xml:
         For swf9, build debug LFC in addition to regular LFC.
         Assume no backtrace library needed for swf9.

    lfc/events/LaszloEvents.lzs:
         Declared _dbg_* variables, they are used conditionally
           in this class (when $debug or $profile are on).

    lfc/debugger/LzMemory.lzs:
          marked _dbg_name as override.

    lfc/data/LzDataElement.lzs:
'_dbg_name' in a mixin exposes a problem. If the usage of the mixin inherits from LzNode, then the method *must* be declared override in the mixin (without some extra compiler smarts). If the usage does not inherit from LzNode, then the method *cannot*
          be declared as override in the mixin.  LzDataElementMixin is
          used in both ways so there is no right way to declare the
          method.  But in this situation (LzDataSet extends LzNode with
LzDataElementMixin), _dbg_name is overridden again. Therefore this method is not currently even being used. In case it would be used in the future, I renamed it, any user class can override
          _dbg_name and call the renamed method.

    lfc/compiler/LzFormatter.lzs
          Changed call from (nonexistent method) this.functionName
          to Debug.functionName().

    sc/SWF9External.java
          Use LFC9-debug.swc when appropriate

Tests:
   0) Regression:
       smokecheck (swf8,dhtml)
       weather (swf8,dhtml,swf9,swf9)  also swf9 with debug=true
       SWF9 hello (with and without &debug=true)

1) Small test xx.lzx illustrates lzc and debug option (-g), with fdb. Note the use of -debug=true flag in the external compiler output and the use of LFC9-debug.swc.

   2) Verified that <canvas debug="true"> also compiles the same way.

3) In the browser, verified that hello.lzx with &debug=true uses the debug LFC by doing 'ls -lu' on lps/includes/lfc, showing the time of access.
