  1. Use faster method to determine open file count 

    QDir is VERY slow for this calculation, because all related
QDir methods require construction of the entry list upfront,
which involves a bunch of extra work in calculating file attributes

In a simple benchtest of trying to open 1000s of files using
the ogr provider ~25% of the time was spent in calculating
open file count. Afterwards this drops to <0.5%.
