Extend scoped_ptr to be closer to unique_ptr. Support custom deleters, and deleting arrays.

This is based on the modifications by "Geoffrey Romer"
 <gromer@google.com> to Google's internal version of scoped_ptr<>.  All cleaver tricks are his, not mine. :)

It brings most of the features of C++11's unique_ptr<> into this class and should eliminate the need for scoped_array<>, scoped_malloc_free<>, and possibly a few other scopers.  Please refer to the unique_ptr<> API for documentation.

Divergence from unique_ptr<>:
1) DefaultDeleter<T[n]> (sized-arrays) is explicitly disabled because this construct would cause the single-object delete to be called on a pointer to a T[n]. It is impossible to construct a single-object new expression that returns a T[n]*. You can only get this with new[] which should correspond to DefaultDeleter<T[n][]>. This issue has been raised with the C++ LWG as it is possible a unique_ptr<> spec defect.

2) Reference types for Deleters are not supported. This simplifies implementation significantly because there is no need to distinguish between the converting constructor + converting assignment operator and their move constructor + move assignment operator.

4) Move-only Deleters are not supported. Avoids the need to emulate std::forward().
