Tatsuhiro Tsujikawa b7c0576eb5 Make certain type of HEADERS subject to priority 
We make following HEADERS under priority control:
* push response HEADERS
* HEADERS submitted by nghttp2_submit_response

Currently, HEADERS submitted by nghttp2_submit_headers is not attached
to stream.  This is because it may be used as non-final response
header and application may submit final response using
nghttp2_submit_response without checking non-final response header
transmission.

Tatsuhiro Tsujikawa e20b417b84 Embed aux_data to nghttp2_outbound_item so that we can save some malloc() calls 2014-09-30 21:45:15 +09:00
Tatsuhiro Tsujikawa 3e3d51842b Interleave stream DATA more naturally 
We simulate resource sharing by decreasing weight.  The thing is if
weight is wrapped, that item continues to send DATA until its weight
gets lowered under the other items.  This commits fix this issue.

Tatsuhiro Tsujikawa da5db205ca Make group weight range [1, 256], inclusive 
We do -+1 on serialization and deserialization since the field is 1
byte.  This change also parameterized range so that we can change it
easily.

Tatsuhiro Tsujikawa 41104f7b63 Abandon DATA frame priority adjustment (again) 
We tried several times about this subject, but for the current
HTTP/2.0 priority scheme, we think it is best to serve the highest
priroty streams first (interleaving streams if there are several
higest ones). There are an issue when aggregating several frontend
connections to one connection in backend, but it is HTTP/2.0
spec issue, rather than implementation.

Tatsuhiro Tsujikawa 1dea4e154b Reintroduce priority adjustment for DATA frame 
This mechanism existed but was deleted. We bring it back in order to
prevent lower priority streams from starving.

Tatsuhiro Tsujikawa 0dec04921d Remove priority adjustment for a DATA frame 
Simply it does not work as expected.
