[svn-r12311] Purpose:
Add pinned entry capability to cache.
Description:
For frequently accessed cache entries, the protect/unprotect overhead
is sometimes a bottleneck.
Solution:
Allow entries to be pinned in the cache. Pinned entries can't be
evicted, but can be flushed or modified.
Platforms tested:
h5committested -- minus one small typo in test/cache.c whose fix was
tested on copper and heping only.
Misc. update:
