Remove race conditions in the statistics code by switching to
Interlocked functions.

Speed up cm_dnlcEnter() by searching first with a read lock and
then switching to a write lock if not found.

Add HKLM\SOFTWARE\OpenAFS\Client registry values "UseDNLC" and "Debug"DNLC".
I suspect with the B+tree code that the DNLC is unnecessary overhead but
leave it on by default for now.

(cherry picked from commit 107899cefaeebe693f8025e9c0d88784facd2236)
