INTEGRATION: CWS configrefactor01 (1.10.24); FILE MERGED

2007/01/16 12:18:28 mmeeks 1.10.24.4: Submitted by: mmeeks
Kill 'memory::Segment' - no longer needed.
Bin some other (empty / redundant) headers.
2007/01/12 14:50:49 mmeeks 1.10.24.3: Another big prune of memory::Accessor ...
2007/01/11 10:35:41 mmeeks 1.10.24.2: Submitted by: mmeeks

Large scale re-factoring, remove fine-grained locking in favor of a simple,
single global lock (still in progress).
Identify and fix various hot-spots.
Remove otherwise empty / non-compiled files.
Kill UpdateAccessor
2007/01/08 20:49:06 mmeeks 1.10.24.1: Issue number:
Submitted by: mmeeks
Substantial configmgr re-factoring #1 ...
+ remove endless typedef chains
+ remove custom allocator & associated complexity
+ remove Pointer, and 'Address' classes
