Merge connection header change from HTTP/2.0 draft
Update the frame header to make the second word always be the stream-ID.

As per HTTP/2.0 changes, # of entries is redundant information with the
length field. For non-stream specific frames, stream-ID is set to 0x0.

Note that 2 frames here had non-trivial changes:
* PING - previously the stream-ID field was a generic ID that would be
  echoed back. Now it's always 0, and the frame payload is an arbitrary
  byte sequence that gets echoed. Also introduces a new flag.
* GOAWAY - previously the stream-ID field was used for the "last good
  stream ID" field. Now it's kept as stream-ID and set to 0. This moves
  the last good stream ID field to the payload ahead of the status code.

Update the frame header to make the second word always be the stream-ID.
SYN_STREAM,SYN_REPLY,HEADERS => HEADERS+PRIORITY,HEADERS

This reduces the number of frames as per HTTP/2.0 draft changes. It also
has the following effects:
* Eliminates some RST_STREAM error codes
* Eliminates the unidirectional stream stuff like HTTP/2.0
* Fixes up some of the push text to say PUSH_PROMISE instead of
  SYN_STREAM
* Removes the unused FLAG_HEADER_END

Update SPDY error handling with HTTP/2.0 changes.

* Copies the stream error handling and error codes from HTTP/2.0 draft
spec.
* In doing so, provides a single list of error codes.

TODO: Remove references to old error codes.
TODO: Update session error handling section too when confusion in that
section is fixed: http://lists.w3.org/Archives/Public/ietf-http-wg/2013AprJun/0719.html
Update RST_STREAM with HTTP/2.0 draft text.

This eliminates the error codes there and references the error code
section.
Update the GOAWAY frame and SessionErrorHandler sections.

Purely editorial changes. Note that the GOAWAY framing change was in an
earlier commit.
