Title: Fix missing const qualifier in name(pair) and value(pair)

Fix missing `const` qualifier in return value of functions `name(const pair&)` and `value(const pair&)`

Otherwise construction like

```cpp
static std::pair headers[] = {
{"connection", "keep-alive"},
{"content-type", "text/xml; charset=\"UTF-8\""},
};
connection->set_headers(boost::make_iterator_range(headers, headers+2));
```
don't compile.
