Tatsuhiro Tsujikawa 53bfc70c9e Include inttypes.h (or cintypes for C++) instead of stdint.h
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.

Tatsuhiro Tsujikawa 514558afc0 Allow NGHTTP2_ERR_TEMPORAL_CALLBACK_FAILURE from nghttp2_on_begin_headers_callback
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.

Tatsuhiro Tsujikawa d56ecd7414 Add nghttp2_session_consume_{connection,stream} to consume bytes independently
The existing nghttp2_session_consume() affects both connection and
stream level flow control windows.  The new functions only affects
either connection or stream.  There is some interesting use cases.
For example, we may want to pause a stream by not sending
WINDOW_UPDATE, meanwhile we want to continue to process other streams.
In this case, we use nghttp2_session_consume_connection() to tell
library that only connection level window is recovered.  The relevant
discussion: https://code.google.com/p/chromium/issues/detail?id=473259

Tatsuhiro Tsujikawa d0c27d5229 Send 24 bytes client magic byte string by library
Previously nghttp2_session_send() and nghttp2_session_mem_send() did
not send 24 bytes client magic byte string (MAGIC).  We made
nghttp2_session_recv() and nghttp2_session_mem_recv() process MAGIC by
default, so it is natural to make library send MAGIC as well.  This
commit makes nghttp2_session_send() and nghttp2_session_mem_send()
send MAGIC.  This commit also replace "connection preface" with
"client magic", since we call MAGIC as "connection preface" but it is
just a part of connection preface.  NGHTTP2_CLIENT_CONNECTION_PREFACE
macro was replaced with NGHTTP2_CLIENT_MAGIC.  The already deprecated
NGHTTP2_CLIENT_CONNECTION_HEADER macro was removed permanently.
nghttp2_option_set_no_recv_client_preface() was renamed as
nghttp2_option_set_no_recv_client_magic().  NGHTTP2_ERR_BAD_PREFACE
was renamed as NGHTTP2_ERR_BAD_CLIENT_MAGIC.

Tatsuhiro Tsujikawa 250ea53e4b Deal with 24 bytes client connection preface by default
Since HTTP/2 spec requires for client to send connection preface, it
is reasonable to make this option enabled by default.  It is still a
use case to disable this, so replace this option with
nghttp2_option_set_no_recv_client_preface().

ALTSVC API for 1.0.0 release.

Tatsuhiro Tsujikawa 9eff511c5e Add nghttp2_send_data_callback to send DATA payload without copying
To avoid buffer copy in nghttp2_data_source_read_callback, this commit
introduces NGHTTP2_DATA_FLAG_NO_COPY and nghttp2_send_data_callback.
By using NGHTTP2_DATA_FLAG_NO_COPY in
nghttp2_data_source_read_callback, application can avoid to copy
application data to given buffer.  Instead, application has to
implement nghttp2_send_data_callback to send complete DATA frame by
itself.  We see noticeable performance increase in nghttpd and
tiny-nghttpd using this new feature.  On the other hand, nghttpx does
not show such difference, probably because buffer copy is not
bottleneck.  Using nghttp2_send_data_callback adds complexity, so it
is recommended to measure the performance to see whether this extra
complexity worth it.

Tatsuhiro Tsujikawa 87029e05af doc: Split API reference into smaller fine grained files
Previously API reference is gigantic one rst file and it is a bit hard
to use, especially when browsing similar functions.  This commit
splits API reference into smaller fine grained files.  The macros,
enums, types are now in its own file.  Each API function has its own
file now.  API reference doc is now index to above documentation
files.  The apiref-header.rst is renamed as programmers-guide.rst and
becomes standalone document.

Tatsuhiro Tsujikawa 2f2a535113 Add a way to send trailer with nghttp2_submit_request/nghttp2_submit_response
nghttp2_submit_request and nghttp2_submit_response will set
NGHTTP2_FLAG_END_STREAM after all given data is sent (data could be
0).  This means we have no way to send trailers.  In this commit, we
added NGHTTP2_DATA_FLAG_NO_END_STREAM flag.  The application can set
this flag in *data_flags inside nghttp2_data_source_read_callback.  If
NGHTTP2_DATA_FLAG_EOF is set, library automatically set
NGHTTP2_FLAG_END_STREAM.  But if both NGHTTP2_DATA_FLAG_EOF and
NGHTTP2_DATA_FLAG_NO_END_STREAM are set, NGHTTP2_FLAG_END_STREAM will
not set by library.  Then application can use new
nghttp2_submit_trailer() to send trailers.  nghttp2_submit_trailer()
will set NGHTTP2_FLAG_END_STREAM and it is actually thing wrapper of
nghttp2_submit_headers().

Tatsuhiro Tsujikawa b685747643 Add nghttp2_submit_shutdown_notice() to start graceful shutdown
nghttp2_submit_shutdown_notice() is used to notify the client that
graceful shutdown is started.  We expect that after this call, the
server application should send another GOAWAY using
nghttp2_submit_goaway() with appropriate last_stream_id.  In this
commit, we also added nghttp2_session_get_last_proc_stream_id(), which
can be used as last_stream_id parameter.

This commit implements graceful shutdown in nghttpx.  The integration
test for graceful shutdown is also added.

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.

Tatsuhiro Tsujikawa 9ff1925538 Robust GOAWAY handling
This change will utilize last_stream_id in GOAWAY extensively.  When
GOAWAY is received with a last_stream_id, library closes all outgoing
streams whose stream_id > received last_stream_id.
nghttp2_on_stream_callback is called for each stream to be closed.

When GOAWAY is sent with a last_stream_id, library closes all incoming
streams whose stream_id > sent last_stream_id.
nghttp2_on_stream_callback is called for each stream to be closed.
