spdy 3 support length 0 header value
Push stream flags into Spdy3.

Previously flags were being interpretted in SpdyConnection
and SpdyStream. This won't work for HTTP/2.0, which has its
own flag setup.
Merge pull request #280 from square/jwilson/push_flags

Push stream flags into Spdy3.
Hide more flags from SPDY APIs.

Flags are not portable between SPDY/3 and HTTP/2.0,
so hide them in the reader & writer code.

Also rename SpdyReader to FrameReader and SpdyWriter to
FrameWriter. Other classes will be renamed as they become
independent of the underlying protocol.
