SecureString

[Jeffrey Walton]

Hi Wei,

I finally got around to doing something with SecureString. It offers
operator (byte*), and all the functionality of basic_string< char >
including the various find*.

* Add the following to secblock.h:
template <class T, class A = AllocatorWithCleanup<T> >
class SecBlock
{
   ...
   template <class U> struct rebind { typedef AllocatorWithCleanup<U> other; };
}

* class 'SecureString' will not compile. Mysteriously, problems appear
with the ctor and conversion from char* to SecureString. Use class
name SecString.
