RFC 7541 requires that dynamic table size update must occur at the
beginning of the first header block, and is signaled as SETTINGS
acknowledgement. This commit checks these conditions. If dynamic
table size update appears other than the beginning of the first header
block, it is treated as error. If SETTINGS ACK is received, and next
HEADERS header block does not have dynamic table size update, it is
treated as error.
This commit fixes the bug that DATA is not consumed if
nghttp2_http_on_data_chunk is failed. It also simplify the handling
of missing stream in NGHTTP2_IB_READ_DATA state.
This commit documents NGHTTP2_ERR_DATA_EXIST also occurs if HEADERS
has been already attached to stream too. This commit also fixes
possible assertion error, and now nghttp2_submit_headers() and
nghttp2_submit_response() may return NGHTTP2_ERR_DATA_EXIST. But we
recommend to use nghttp2_submit_request() and
nghttp2_submit_response(), and using them will avoid this error.

* modernize python bindings creation
* some minor refactoring
Previously, we did not handle PRIORITY frame which depends on itself
and for idle stream. As a result, nghttp2_session_mem_recv (or
nghttp2_session_recv) returne NGHTTP2_ERR_NOMEM. The error code was
still misleading. It was not out of memory, and we failed to insert
hash map because of duplicated key, which was treated as out of
memory. This commit fixes this issue, by explicitly checking
dependency for incoming PRIORITY for all cases.
When we know that stream is closed at time we read DATA frame header,
we use NGHTTP2_IB_IGN_DATA, and consume data for connection if
nghttp2_option_set_no_auto_window_update() is used. However, if
stream is closed while we are in NGHTTP2_IB_READ_DATA, those bytes are
not consumed for connection, nor notified to application via callback,
so it eventually fills up connection window and connection will
freeze. This commit fixes this issue by consuming these data for
connection when stream is closed or does not exist.
The private global variable nghttp2_enable_strict_preface is also
marked as NGHTTP2_EXTERN, but it is test purpose only (test with
.dll), and not part of public API. It could be removed in the future
release.
From autoconf manual, section 5.6.1 Portability of Headers, says:
"""
The C99 standard says that inttypes.h includes stdint.h, so there's no
need to include stdint.h separately in a standard environment. Some
implementations have inttypes.h but not stdint.h (e.g., Solaris 7),
but we don't know of any implementation that has stdint.h but not
inttypes.h.
"""
The assert only evaluates to code if NDEBUG is undefined. Protect rv and its use accordingly

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.
Since application most likely allocates the stream object in
nghttp2_on_begin_headers_callback, it is desirable to handle its
failure as stream error. But previously it only signals success or
fatal error. Submitting RST_STREAM does not prevent
nghttp2_on_header_callback from being invoked. This commit improves
this situation by allowing NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE from
nghttp2_on_begin_headers_callback. If that value is returned, library
submits RST_STREAM with error code INTERNAL_ERROR, and
nghttp2_on_header_callback and nghttp2_on_frame_recv_callback for that
frame are not invoked. Note that for PUSH_PROMISE frame, the stream
to be reset is promised stream.
