> Implicit typecast from 'void *' to 'T *' is okay in C, but not in
> C++. In talloc_steal, an explicit cast is provided for type safety in
> some GCC versions. Otherwise, a cast is required. Provide a template
> function for this to maintain type safety, and redefine talloc_steal
> to use it.
> The template must be outside the extern "C" block (NOTMUCH_BEGIN_DECLS
> and NOTMUCH_END_DECLS), but keep it within the GCC visibility #pragma.
> No functional changes, apart from making the library build with
> compilers other than recent GCC.
