• if Qt4 depending version stable, remove Qt3 depending versions
  
• if Qt4 depending version in testing, mark stable, then remove older
  versions
  
• if no Qt4 version in tree, get Qt4 version in testing by 2010-01-21
  and stable by 2010-02-21
  
• if no Qt4 version exists, check for equivalent/replacement packages,
  and mask by Feb. 21.

Note: for packages that currently have no version marked stable, the
references to stabling Qt4 versions obviously don’t apply.
