String::NewExternal should not crash the renderer.

The blink may pass a very long string to v8
for making a handle to it. v8 has max string length
limit and creates exception. But NewExternal code does not
check that the handle is null and crashes the renderer.

With the fix the js code receives the exception.

Script streaming: fix split UTF-8 character handling.

Invalid UTF-8 data can contain too many characters which look like they're part
of a multi-byte character, and that was overflowing a buffer.
