John Mainzer a9ba92287d [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

# A map from type name to type letter. We use this map for two reasons:
# 1. We want the debugging stuff in the source code to be as unobtrusive as
# possible, which means as compact as possible.
# 2. It's easier (faster) to parse these one and two-letter types in the C
# functions that display debugging results.
#
# All type strings are one or two characters. One-character strings
# are always lower case and should be used for common types.
# Two-character strings begin with an upper-case letter which is
# usually the same as the package name.
