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.
