[svn-r18230] Description:
Bring r18229 from metadata journaling "merging" branch into trunk: Bring r18227 from metadata_journaling branch to the merging branch: Small cleanups and move v1 cache maintenance macros into package header file, to better align with changes to v2 cache.

+ *
+ * We maintain doubly linked lists of instances of H5C_cache_entry_t for a
+ * variety of reasons -- protected list, LRU list, and the clean and dirty
+ * LRU lists at present. The following macros support linking and unlinking
+ * of instances of H5C_cache_entry_t by both their regular and auxilary next
+ * and previous pointers.
+ *
+ * The size and length fields are also maintained.
+ *
+ * Note that the relevant pair of prev and next pointers are presumed to be
+ * NULL on entry in the insertion macros.
+ *
+ * Finally, observe that the sanity checking macros evaluate to the empty
+ * string when H5C_DO_SANITY_CHECKS is FALSE. They also contain calls
+ * to the HGOTO_ERROR macro, which may not be appropriate in all cases.
+ * If so, we will need versions of the insertion and deletion macros which
+ * do not reference the sanity checking macros.
+ * JRM - 5/5/04
+ *
+ * Changes:
+ *
+ * - Removed the line:
+ *
+ * ( ( (Size) == (entry_ptr)->size ) && ( (len) != 1 ) ) ||
+ *
+ * from the H5C__DLL_PRE_REMOVE_SC macro. With the addition of the
+ * epoch markers used in the age out based cache size reduction algorithm,
+ * this invarient need not hold, as the epoch markers are of size 0.
+ *
+ * One could argue that I should have given the epoch markers a positive
+ * size, but this would break the index_size = LRU_list_size + pl_size
+ * + pel_size invarient.
+ *
+ * Alternatively, I could pass the current decr_mode in to the macro,
+ * and just skip the check whenever epoch markers may be in use.
+ *
+ * However, any size errors should be caught when the cache is flushed
+ * and destroyed. Until we are tracking such an error, this should be
+ * good enough.
+ * JRM - 12/9/04
+ *
+ *
+ * - In the H5C__DLL_PRE_INSERT_SC macro, replaced the lines:
+ *
+ * ( ( (len) == 1 ) &&
+ * ( ( (head_ptr) != (tail_ptr) ) || ( (Size) <= 0 ) ||
+ * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
+ * )
+ * ) ||
+ *
+ * with:
+ *
+ * ( ( (len) == 1 ) &&
+ * ( ( (head_ptr) != (tail_ptr) ) ||
+ * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
+ * )
+ * ) ||
+ *
+ * Epoch markers have size 0, so we can now have a non-empty list with
+ * zero size. Hence the "( (Size) <= 0 )" clause cause false failures
+ * in the sanity check. Since "Size" is typically a size_t, it can't
+ * take on negative values, and thus the revised clause "( (Size) < 0 )"
+ * caused compiler warnings.
+ * JRM - 12/22/04
+ *
+ * - In the H5C__DLL_SC macro, replaced the lines:
+ *
+ * ( ( (len) == 1 ) &&
+ * ( ( (head_ptr) != (tail_ptr) ) || ( (cache_ptr)->size <= 0 ) ||
+ * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
+ * )
+ * ) ||
+ *
+ * with
+ *
+ * ( ( (len) == 1 ) &&
+ * ( ( (head_ptr) != (tail_ptr) ) ||
+ * ( (head_ptr) == NULL ) || ( (head_ptr)->size != (Size) )
+ * )

+ * take on negative values, and thus the revised clause "( (Size) < 0 )"
+ * caused compiler warnings.
+ * JRM - 1/10/05
+ *
+ * - Added the H5C__DLL_UPDATE_FOR_SIZE_CHANGE macro and the associated
+ * sanity checking macros. These macro are used to update the size of
+ * a DLL when one of its entries changes size.

+ * JRM - 9/8/05
