Changes with nginx 1.19.2 11 Aug 2020

*) Change: now nginx starts closing keepalive connections before all
free worker connections are exhausted, and logs a warning about this
to the error log.

*) Change: optimization of client request body reading when using
chunked transfer encoding.

*) Bugfix: memory leak if the "ssl_ocsp" directive was used.

*) Bugfix: "zero size buf in output" alerts might appear in logs if a
FastCGI server returned an incorrect response; the bug had appeared
in 1.19.1.

*) Bugfix: a segmentation fault might occur in a worker process if
different large_client_header_buffers sizes were used in different
virtual servers.

*) Bugfix: SSL shutdown might not work.

*) Bugfix: "SSL_shutdown() failed (SSL: ... bad write retry)" messages
might appear in logs.

*) Bugfix: in the ngx_http_slice_module.

*) Bugfix: in the ngx_http_xslt_filter_module.
