[svn-r10688] Purpose:
Add API calls allowing user control of the metadata cache.
Description:
Prior to this update, the metadata cache was not configurable
from outside the library.
Solution:
Add API calls allowing the user to configure the metadata cache
either at file open time, or for any open file. Also added calls
permitting the user to monitor cache size and hit rate. These
latter facilities are needed for "manual" cache size control
Platforms tested:
h5committested
