basic_string<> - patch

[Ryszard Kabatek]

The _S_construct function call the _S_copy_chars function.
_S_copy_chars is a template function with a specialization for const _CharT*.
It is to few. 
I added three specializations, for _CharT*, iterator and const_iterator.

I expected the specializations for const _CharT* and const_iterator would
be enough, but it is not the case :-( we need the specializations
for _CharT* and iterator too.
