Reviewed by Alexander Pavlov.

Introduce conversion mode to String::utf8().
There are three conversion modes; lenient mode, strict mode, and
"replacing unpaired surrogates with the replacement character" (replacement) mode.
Lenient mode converts unpaired surrogates. Strict mode fails when there is an unpaired
surrogates and returns CString(). Replacement mode replaces unpaired surrogates with
the replacement character(U+FFFD). Replacement mode implements the algorithm defined at
http://dev.w3.org/2006/webapi/WebIDL/#dfn-obtain-unicode. WebSocket::send() requires
this algorithm to encode a string to utf-8.

* wtf/text/WTFString.cpp:
(WTF::String::utf8): Changed to take ConversionMode as the argument.
