[svn-r12595] Modified H5C_insert_entry() to accept the H5C__PIN_ENTRY_FLAG entry
flag, and pin an entry as it is inserted.

The objective is to avoid some function call overhead in fheap.

Also added matching test code in test/cache.c & test/cache_common.c
(also testpar/t_cache.c checked in separately by accident)
