Tatsuhiro Tsujikawa 392256e542 Add nghttp2_option_set_max_deflate_dynamic_table_size() API function
nghttp2_option_set_max_deflate_dynamic_table_size function sets the
maximum dynamic table size for header block deflater.  The default
value is 4KiB.

Tatsuhiro Tsujikawa 6858cda366 Fix GOAWAY race with new incoming stream on server side
Revert part of 16c46114dc to fix race
condition that incoming stream after sending GOAWAY causes connection
error.  The strict stream handling introduced in the above commit does
not handle several cases well (e.g., GOAWAY race, and refusing streams
because of concurrency limit).

Tatsuhiro Tsujikawa 5cf21ec187 Add APIs to return the number of data that remote endpoint can send
2 APIs are added.  nghttp2_session_get_local_window_size() returns the
amount of data that the remote endpoint can send without receiving
connection level WINDOW_UPDATE.
nghttp2_session_get_stream_local_window_size() returns the amount of
data that the remote endpoint can send without receiving stream level
WINDOW_UPDATE.

Tatsuhiro Tsujikawa 9b864380a5 Use nghttp2_vec in nghttp2_hd_deflate_hd_vec
This change is for the future enhancement where we loose the
requirement about the chunk size for each buffer.

Tatsuhiro Tsujikawa 16c46114dc More strict stream state handling
Previously, in server side, we used closed streams to detect the error
that the misbehaving client sends a frame on the incoming stream it
explicitly closed.  With this commit, we make a further step, and
detect one more error case.  Since we retain closed streams as long as
the sum of its size and the number of opened streams are equal or less
than max concurrent streams, we can safely say that if we get a frame
which is sent on the stream that is not found in either closed or
opened stream, it is already closed or has not existed.  Then we can
send GOAWAY.

The previous code shrinks closed streams when we closed another
stream, but now it is removed.  It is enough to adjust closed streams
when new incoming stream is created.

While creating this commit, we noticed that
NGHTTP2_INITIAL_MAX_CONCURRENT_STREAMS is defined as INT32_MAX.  But
since SETTINGS can contain value up to UINT32_MAX, it is not enough.
However, since the stream ID space is limited to INT32_MAX, it is high
enough.  We could keep this value, but this time we deprecate
NGHTTP2_INITIAL_MAX_CONCURRENT_STREAMS macro.  While it is in public
header, the effect of deprecating it is negligible because of the
reason we wrote above, and usually application sets much smaller value
(say, 100) as SETTINGS_MAX_CONCURRENT_STREAMS.

Tatsuhiro Tsujikawa 2f106dc96b Fix wrong tree operation to avoid cycle
https://tools.ietf.org/html/rfc7540#section-5.3.3 explains how to
transform dependency tree to avoid circular dependency.  Previously,
we wrongly always moved the dependent stream under the root stream.
The correct destination is the parent stream of the stream to
reprioritize.  This commit fixes this bug.

Tatsuhiro Tsujikawa 271f7fbbb6 Add nghttp2_on_invalid_header_callback
nghttp2_on_invalid_header_callback is similar to
nghttp2_on_header_callback, but the former is only called when the
invalid header field is received which is silently ignored when the
callback is not set.  With this callback, application inspects the
incoming invalid field, and it also can reset stream from this
callback by returning NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE, or using
nghttp2_submit_rst_stream() directly with the error code of choice.

We also added nghttp2_on_invalid_header_callback2, which uses
reference counted header fields.

Tatsuhiro Tsujikawa 110ca3131a Cancel frame transmission from before_frame_send_callback
We define the behaviour when NGHTTP2_ERR_CANCEL is returned from
before_frame_send_callback.  That is to cancel the frame passed to the
callback.

Tatsuhiro Tsujikawa c7b0e04498 Add nghttp2_option_set_max_send_header_block_length API function
This function sets the maximum length of header block (a set of header
fields per HEADERS frame) to send.  The length of given set of header
fields is calculated using nghttp2_hd_deflate_bound().  Previously,
this is hard-coded, and is 64KiB.

Tatsuhiro Tsujikawa 2a96d433ec Add nghttp2_hd_inflate_hd2() and deprecate nghttp2_hd_inflate_hd()

parameter, which is desirable since it is effectively read-only.

Peter Wu 7f8110601e cmake: fix compatibility with cmake before 3.3
The COMPILE_LANGUAGE generator expression is only supported since CMake
3.3. Moreover, it does not work with all generators (works with Makefile
and Ninja, but not with Visual Studio).

target_compile_options would only work if a target does not mix C and
C++ sources, since the flags are intended to be set for a specific
language, use set_source_files_properties instead. This approach is also
less repetitive.

Drop the idea of using lists and COMPILE_OPTIONS,
set_source_files_properties only understands COMPILE_FLAGS (a single
string, not a list).

Tatsuhiro Tsujikawa e453759637 Add nghttp2_option_set_no_auto_ping_ack() option
This option prevents the nghttp2 library from sending PING frame with
ACK flag set in the reply to incoming PING frame.  To allow the
application to send PING with ACK flag set, nghttp2_submit_ping() now
recognizes NGHTTP2_FLAG_PING in its flags parameter.

Peter Wu 77e8190b6c cmake: fix symbol visibility issues
libnghttp2.so was missing -fvisibility=hidden. libnghttp2_asio.so on the
other hand had hidden visibility which resulted in no exported symbols
and a broken asio client examples.

Just build a static nghttp2 library to solve this issue.

Peter Wu 63e43bff99 tests: remove unused macros
Since v0.6.2-7-g1d138ac ("Unify DATA and other frames in

builds fails on -Werror=unused-macros.

Peter Wu 8c46d9181f cmake: process tests directory
Split the nghttp2 library into objects and a shared library from those
objects. This is needed because of symbol visibility. An advantage over
the autotools build is that there are no worries about static versus
static library builds.

Test:

    cmake $srcdir
    make nghttpx-unittest main failmalloc
    make test

Tatsuhiro Tsujikawa 4a78f59e7b Rename nghttp2_session.sent_stream_id as last_sent_stream_id
This is more accurate, and there is symmetric relation between
last_sent_stream_id and last_recv_stream_id, which is bettern fit in
my sense.

Tatsuhiro Tsujikawa bb6f842b37 Check request/response submission error based side of session
Disallow request from server, and response from client respectively.
When the violation is detected, return NGHTTP2_ERR_PROTO from
nghttp2_submit_request, nghttp2_submit_response,
nghttp2_submit_headers.

We also did some refactoring, and now self-dependency detection is
placed where it is only required.

Tatsuhiro Tsujikawa 9cea986819 Strict outgoing idle stream detection
Previously, we use session->next_stream_id to detect that given stream
ID was idle or not.  But this was suboptimal, since it was updated
when stream ID was assigned, and it did not necessarily mean that it
actually has been sent to the peer.  Now we introduced
session->sent_stream_id, which only updated when HEADERS/PUSH_PROMISE
has sent.  Using sent_stream_id instead of next_stream_id tightens
idle stream detection, and misbehaved peer which sends frame with
stream ID that has not been generated.

This commit also overhauls test code which involves opening streams.
Now we have some wrapper functions for nghttp2_session_open_stream()
which also take care of updating next_stream_id and
last_recv_stream_id.  They are crucial for some tests.
