Don't let storages inherit from boost::noncopyable
... IStorage has deleted copy ctor / assignment already

Remove inherited create() method + disallow copying
The original motivation for this commit was that shared_ptr_helper used
std::shared_ptr<>() which does two heap allocations instead of
make_shared<>() which does a single allocation. Turned out that
1. the affected code (--> Storages/) is not on a hot path (rendering the
performance argument moot ...)
2. yet copying Storage objects is potentially dangerous and was
   previously allowed.

Hence, this change

- removes shared_ptr_helper and as a result all inherited create() methods,

- instead, Storage objects are now created using make_shared<>() by the
  caller (for that to work, many constructors had to be made public), and

- all Storage classes were marked as noncopyable using boost::noncopyable.

In sum, we are (likely) not making things faster but the code becomes
cleaner and harder to misuse.
