The maximum number of outgoing concurrent streams is initially
limited to 100 to avoid issues when the local endpoint submits
lots of requests before receiving initial SETTINGS frame from
the remote endpoint, since sending them at once to the remote
endpoint could lead to rejection of some of the requests.
This initial limit is overwritten with the value advertised in
SETTINGS_MAX_CONCURRENT_STREAMS setting by the remote endpoint,
but previously, it wasn't lifted if the remote endpoint didn't
advertise that setting (implying no limits), in which case the
limit of 100 was retained, even though it was never advertised
by the remote endpoint.

The error code NGHTTP2_REFUSED_STREAM is passed to
nghttp2_on_stream_close callback when a stream is closed because its
stream ID is strictly larger than incoming or outgoing GOAWAY.
nghttp2_error_callback2 is an extended version of the existing
nghttp2_error_callback by adding error code parameter. This
deprecates nghttp2_error_callback.
Add a `nghttp2_rcbuf_is_static()` method to tell whether a rcbuf
is statically allocated.
This can be useful for language bindings that wish to avoid
creating duplicate strings for these buffers; concretely, I am
planning to use this in the Node HTTP/2 module that is being
introduced.
Previously, the incoming invalid regular header field was ignored by
default. With this commit, they are now treated as stream error, and
the stream is reset by default. The error code used is now
PROTOCOL_ERROR, instead of INTERNAL_ERROR.
This commit fixes the bug in nghttp2_session_want_write. Previously,
it may return 0 if there is pending frames after GOAWAY frame is
submitted.
To avoid the situation that nghttp2_session_want_write keeps returning
nonzero after GOAWAY and the number of active streams is 0 (e.g., keep
receiving SETTINGS or PING), nghttp2_session_mem_recv now just
swallows the input data without parsing in this case.
