Arjen Poutsma 510436bae9 Copy header values instead of header lists in DefaultClientRequestBuilder ...

This commit changes the `headers(HttpHeaders)` method in
DefaultClientRequestBuilder so that it copies the individual header
values instead of using the `List<String>` value directly. The reason
for this change is that the list of values can be immutable, and adding
additional values after that could result in
UnsupportedOperationExceptions.
