Deprecate SPDY/3.1 and draft HTTP/2 enum values.

Deprecate SPDY/3.1 and draft HTTP/2 enum values.

* Remove NextProto::kProtoSPDY31 enum value.
* Remove unused enum NextProto values: kProtoSPDY31, kProtoMinimumVersion,
  kProtoMaximumVersion, kProtoSPDYMinimumVersion, kProtoSPDYMaximumVersion.
* Remove (and inline) now trivial NextProtoIsSPDY(); remove next_proto.cc.
* Deprecate enum HttpResponseInfo values: CONNECTION_INFO_SPDY3,
  CONNECTION_INFO_HTTP2_14, CONNECTION_INFO_HTTP2_15.

SPDY/3.1, HTTP/2 draft-14, and HTTP/2 draft-15 protocols are not supported any
more.  This CL cleans up deprecated enum values: removes them where it is
possible, marks them DEPRECATED where it is not.
