extension frames.  These frames are expected not to change existing
protocol behaviour.

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 661fb2eb0e NULL-terminate name and value in nghttp2_nv
Guaranteeing NULL-termination is very useful when name or value are
used with C functions which requires NULL-terminated string.

Tatsuhiro Tsujikawa c0ffed7788 Support custom memory allocator
nghttp2_mem structure is introduced to hold custom memory allocator
functions and user supplied pointer.  nghttp2_mem object can be passed
to nghttp2_session_client_new3(), nghttp2_session_server_new3(),
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 31528b6267 Use uint32_t for HTTP/2 error_code
h2-14 now allows extensions to define new error codes.  To allow
application callback to access such error codes, we uses uint32_t as
error_code type for structs and function parameters.  Previously we
treated unknown error code as INTERNAL_ERROR, but this change removes
this and unknown error code is passed to application callback as is.

Tatsuhiro Tsujikawa dacc9b2f1c Separate extension frames from core frames
ALTSVC and BLOCKED frames are now extension frames.  To add new
extension frame without modifying nghttp2_frame union, which causes so
name bump, we separated extension frames from core frames.
nghttp2_frame includes generic nghttp2_extension.  The payload member
of nghttp2_extension will point to the structure of extension frame
payload.  The frame types of extension frames are defined in
nghttp2_ext_frame_type.

Tatsuhiro Tsujikawa ab76468971 Return NGHTTP2_ERR_BUFFER_ERROR from nghttp2_hd_{deflate,inflate}_hd
It is generally useful to know what is the cause of the error.  Since
we expose HPACK API, it is friendly to tell application the
insufficient buffer size is a culprit.

Tatsuhiro Tsujikawa bc6d952361 Check max SETTINGS_HEADER_TABLE_SIZE in nghttp2_iv_check()
Hide NGHTTP2_MAX_HEADER_TABLE_SIZE from public API.  Now it is defined
as ((1u << 31) - 1) in nghttp2_frame.h, which is sufficiently big
enough.

Tatsuhiro Tsujikawa e8de437d5c Return new stream ID from nghttp2_submit_{request, headers, push_promise}
Previously stream ID was assigned just before HEADERS or PUSH_PROMISE
was serialized and nghttp2_submit_{request, headers, push_promise} did
not return stream ID.  The application has to check assigned stream ID
using before_frame_send_callback.  Now it is apparent that priority is
meant to DATA transfer only.  Also application can reorder the
requests if it wants. Therefore we can assign stream ID in
nghttp2_submit_* functions and return stream ID from them.  With this
change, now application does not have to check stream ID using
before_frame_send_callback and its code will be simplified.

Tatsuhiro Tsujikawa 052be3296c Implement compressed DATA
The library interface supports compressed DATA.  The library does not
deflate nor inflate data payload.  When sending data, an application
has to compress data and set NGHTTP2_DATA_FLAG_COMPRESSED to
data_flags parameter in nghttp2_data_source_read_callback.  On
receiving, flags parameter in nghttp2_on_data_chunk_recv_callback
includes NGHTTP2_FLAG_COMPRESSED.  An application should check the
flags and inflate data as necessary.  Since compression context is per
frame, when DATA is seen in nghttp2_on_frame_recv_callback, an
application should reset compression context.

Tatsuhiro Tsujikawa da5db205ca Make group weight range [1, 256], inclusive
We do -+1 on serialization and deserialization since the field is 1
byte.  This change also parameterized range so that we can change it
easily.
