[phobos] Sealed Hash Tables

[Steve Schveighoffer]

I am not an expert in allocators.  However, feel free to use my dcollections 
chunk allocator and related API.

I just implemented what I thought would be good.  I handle the free individual 
elements question by a freeNeeded enum.  The freeAll I figure can be a noop for 
allocators that don't care, since it's not called frequently.

freeNeeded could potentially be an external template instead of an internal 
enum.  I wrote that code long before I was using d2 and had experience with 
Andrei's excellent type checking code.

Anyways, use what you want.  It's boost 1.0 license.
