Thanks a lot for this patch.  This helps identify those code blocks that
can potentially be removed later.

One correction is needed however.  You've used #ifndef .... #endif block
throughout the code base to conditionally disable code blocks, but the
better way is to define in global.hxx

#define SC_WITH_LEGACY_ADDIN 1

and use

#if SC_WITH_LEGACY_ADDIN

  code block

#endif

This way, all you have to do to enable/disable the code is to toggle the
value of SC_WITH_LEGACY_ADDIN in the global.hxx and re-compile.

Another thing is to associate the value of 1 to enabling, and the value
of 0 to disabling, to make it easier for the brain to process this, as
it requires a bit of extra work mentally to process 0 for enabling and 1
for disabling.

Thanks!
