SPDY: fix support for headers with multiple values.

Split SPDY header with multiple, NULL-separated values:

    cookie: foo\0bar

into two separate HTTP headers with the same name:

    cookie: foo
    cookie: bar

Even though the logic for this behavior already existed
in the source code, it doesn't look that it ever worked
and SPDY streams with such headers were simply rejected.
