Tatsuhiro Tsujikawa 5b59e46e2b Rewrite priority handling
We now use priority queue per stream, which contains the stream which
has ready to send a frame, or one of its descendants have a frame to
send.  We maintain invariant that if a stream is queued, then its
ancestors are also queued (except for root).  When we re-schedule
stream after transmission, we re-schedule all ancestors, so that
streams on the other path can get a chance to send.  This is basically
the same mechanism h2o project uses, but there are differences in the
details.

Tatsuhiro Tsujikawa f2cf2b625c Replace priority queue with linear queue where possible
After reviewing codebase, only queue for DATA frames requires
priorities.  Other frames can be replaced multiple linear queues.
Replacing priority queue with linear queue allows us to simplify
codebase a bit; for example, now nghttp2_session.next_seq is gone.

Tatsuhiro Tsujikawa 442572c1f4 Handle situation where request HEADERS in queue is reset by RST_STREAM
Previously we did not handle the situation where RST_STREAM is
submitted against a stream while requet HEADERS which opens that
stream is still in queue.  Due to max concurrent streams limit,
RST_STREAM is sent first, and then request HEADERS, which effectively
voids RST_STREAM.

In this commit, we checks RST_STREAM against currently pending request
HEADERS in queue and if stream ID matches, we mark that HEADERS as
canceled and RST_STREAM is not sent in this case.  The library will
call on_frame_not_sent_callback for the canceled HEADERS with error
code from RST_STREAM.

Tatsuhiro Tsujikawa c0ffed7788 Support custom memory allocator
nghttp2_mem structure is introduced to hold custom memory allocator
functions and user supplied pointer.  nghttp2_mem object can be passed
to nghttp2_session_client_new3(), nghttp2_session_server_new3(),
nghttp2_hd_deflate_new2() and nghttp2_hd_inflate_new2() to replace
standard malloc(), free(), calloc() and realloc().  nghttp2_mem
structure has user supplied pointer mem_user_data which can be used as
per session/object memory pool.
