WL# 2986

Browse Source 
Final patch
-----------

This WL is about using this bitmap in all parts of the partition handler.
Thus for:
rnd_init/rnd_next
index_init/index_next and all other variants of index scans
read_range_... the various range scans implemented in the partition handler.

Also use those bitmaps in the various other calls that currently loop over all
partitions.
