Check the allowed characters for ":method" (see RFC 7230, section 3.2.6) and
":path". For ":path", the space and tab characters are now forbidden, but
other special characters are still allowed for compatibility reasons.
Update genvchartbl.py so that it generates the same table as in the code.
Fixes#1611
The previous wording implied that if send_callback doesn't return
NGHTTP2_ERR_WOULDBLOCK, this function would always send all
submitted requests / data. This is not the case, since flow control can
cause some data to remain queued until WINDOW_UPDATE is received.
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.

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.
nghttp2_option_no_closed_streams controls whether closed streams are
retained or not. If nonzero is passed to that function's parameter
val, a session does not retain closed streams. It may hurt the shape
of priority tree, but can save memory.
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.
