D14956: avoid any heap allocation for default constructed Format() as used as "invalid"

[Volker Krause]

vkrause added a comment.


  A shared static null object should work with QExplicitlySharedDataPointer as with any other d pointer type: just copy the null object into d in the default ctor. Trades the conditions per call for an atomic increment/decrement per instance.
