* Attribute caching module.

* $Id: attrcache.cpp 3049 2007-12-30 06:35:41Z brazilofmux $

* The functions here manage the upper-level attribute value cache for

* disk-based mode. It's not used in memory-based builds. The lower-level

* cache is managed in svdhash.cpp

* The upper-level cache is organized by a CHashTable and a linked list. The

* former allows random access while the linked list helps find the

* least-recently-used attribute.
