Hey y'all. 

I noticed the repeated, repeated, repeated use of
std::allocator forward decls as I was trying to debug some doxygen

Clearly, it's past time for a memory forward header, like
bits/stringfwd.h. The following patch implements this. Perhaps some of
the other headers can now be optimized because of this, but that was
not my primary focus. Instead, I was just trying to come up with the
smallest patch that was semantically equivalent to existing trunk.

tested x86/linux
