[svn-r13618] Modified metadata cache to support multiple read only protects of
cache entries. Added test code to test the new feature. Also some
minor cleanum
h5committested -- passed on copper and sol. Failed on osage with
a configuration error that appears unrelated to my changes. Serial
test (debug mode) passes on Phoenix (Linux x86 2.6 kernel), so I
went ahead with the checkin.
