Range access, try 2

[Ed Smith-Rowland <3dw4rd at verizon dot net>]

Greetings,

Here is another go at the library part of range access.

I added range access to <iterator> as required.

I made everything inline because all the functions are returning member 
begin() or end() or a pointer.

I added compile-only test cases.

In my testing I didn't see anything that I could ascribe to this patch 
but there were gomp errors, abi errors involving moneypunct and similar.

I will try this patch myself on a clean new tree but I thought folks 
should have a look.

Ed
