boost::asio::buffer() overload for string_ref and const char pointer (c-string)

[oliora@…]

There are many overloads of boost::asio::buffer() including ones for std::string and POD array, but there are no overloads for const char * and for boost::basic_string_ref<char, ...>. I propose to add such overloads.

Why can't we use the constructor for void* ? There is no need for separate constructor for const char*

Patch for handling const char *

[oliora@…]

I meant ctor which accepts const char * without the length and calls strlen() internally:

const_buffers_1 buffer(const char* s) {
    return buffer(s, std::strlen(s));
}

Ctor for string_ref:

template<class Traits>
inline const_buffers_1 buffer(const boost::basic_string_ref<char, Traits>& s) {
    return buffer(s.data(), s.size());
}

P.S. In previous example I forgot inline.
