nghttp2: updated to 1.60.0

Nghttp2 v1.60.0

lib

RFC 7540 priorities (aka stream dependencies) APIs have been deprecated. They \ 
work just like before, but in the future release after the end of 2024, the \ 
functionality is removed, and the deprecated APIs start behaving differently. \ 
See the API documentation for details. RFC 7540 priorities have been deprecated \ 
by RFC 9113. Consider migrating RFC 9218 extensible prioritization scheme.

The APIs that use ssize_t, including structs and callback functions, have been \ 
deprecated. New APIs that use nghttp2_ssize are introduced as a replacement. The \ 
usage of ssize_t is problematic for several reasons. Some platforms do not \ 
define ssize_t. The minimum value of ssize_t that POSIX requires is -1 which \ 
makes nghttp2 error code out of range. nghttp2_ssize is an alias of ptrdiff_t \ 
that is in C standard and covers our error code range.

New code should use new nghttp2_ssize APIs. The existing applications should \ 
consider migrating to new APIs.

The deprecated ssize_t APIs continue to work for backward compatibility.

Here is the summary of the deprecated APIs and their replacements:

Callback functions:

nghttp2_data_source_read_callback => nghttp2_data_source_read_callback2
nghttp2_data_source_read_length_callback => \ 
nghttp2_data_source_read_length_callback2
nghttp2_pack_extension_callback => nghttp2_pack_extension_callback2
nghttp2_recv_callback => nghttp2_recv_callback2
nghttp2_select_padding_callback => nghttp2_select_padding_callback2
nghttp2_send_callback => nghttp2_send_callback2

Structs:

nghttp2_data_provider => nghttp2_data_provider2

Functions:

nghttp2_hd_deflate_hd => nghttp2_hd_deflate_hd2
nghttp2_hd_deflate_hd_vec => nghttp2_hd_deflate_hd_vec2
nghttp2_hd_inflate_hd2 => nghttp2_hd_inflate_hd3
nghttp2_pack_settings_payload => nghttp2_pack_settings_payload2
nghttp2_session_callbacks_set_data_source_read_length_callback => \ 
nghttp2_session_callbacks_set_data_source_read_length_callback2
nghttp2_session_callbacks_set_pack_extension_callback => \ 
nghttp2_session_callbacks_set_pack_extension_callback2
nghttp2_session_callbacks_set_recv_callback => \ 
nghttp2_session_callbacks_set_recv_callback2
nghttp2_session_callbacks_set_select_padding_callback => \ 
nghttp2_session_callbacks_set_select_padding_callback2
nghttp2_session_callbacks_set_send_callback => \ 
nghttp2_session_callbacks_set_send_callback2
nghttp2_session_mem_recv => nghttp2_session_mem_recv2
nghttp2_session_mem_send => nghttp2_session_mem_send2
nghttp2_submit_data => nghttp2_submit_data2
nghttp2_submit_request => nghttp2_submit_request2
nghttp2_submit_response => nghttp2_submit_response2
For those applications that do not want to see ssize_t in nghttp2.h header file \ 
at all, define NGHTTP2_NO_SSIZE_T macro before including nghttp2.h. It hides all \ 
ssize_t APIs.
