Ticket #48010 - winsync range retrieval gets only 5000 values upon initialization
Description: Search with DirSync control does not support range subtype.
On WS2012, it returns all the multi-valued attribute values regardless
of MaxValRange, but on WS2008, it cuts at the physical limit 5000.
This patch does not rely on the entry returned by the DirySync search.
Also, since DirSync search does not support the range subtype, removing
the range related code from the DirSync search.
