nginx-devel: updated to 1.15.7

Changes with nginx 1.15.7:
*) Feature: the "proxy_requests" directive in the stream module.
*) Feature: the "delay" parameter of the "limit_req" directive.
*) Bugfix: memory leak on errors during reconfiguration.
*) Bugfix: in the $upstream_response_time, $upstream_connect_time, and

*) Bugfix: a segmentation fault might occur in a worker process if the
   ngx_http_mp4_module was used on 32-bit platforms.

Log message:
nginx-devel: updated to 1.15.6

Changes with nginx 1.15.6:

*) Security: when using HTTP/2 a client might cause excessive memory
   consumption (CVE-2018-16843) and CPU usage (CVE-2018-16844).

*) Security: processing of a specially crafted mp4 file with the
   ngx_http_mp4_module might result in worker process memory disclosure
   (CVE-2018-16845).

*) Feature: the "proxy_socket_keepalive", \ 
"fastcgi_socket_keepalive",
   "grpc_socket_keepalive", "memcached_socket_keepalive",
   "scgi_socket_keepalive", and "uwsgi_socket_keepalive" \ 
directives.

*) Bugfix: if nginx was built with OpenSSL 1.1.0 and used with OpenSSL
   1.1.1, the TLS 1.3 protocol was always enabled.

*) Bugfix: working with gRPC backends might result in excessive memory
   consumption.

Log message:
nginx-devel: updated to 1.15.5

Changes with nginx 1.15.5:

*) Bugfix: a segmentation fault might occur in a worker process when
   using OpenSSL 1.1.0h or newer; the bug had appeared in 1.15.4.

*) Bugfix: of minor potential bugs.

Changes with nginx 1.15.4:

*) Feature: now the "ssl_early_data" directive can be used with OpenSSL.

   Thanks to Chris Caputo.

*) Bugfix: connections with some gRPC backends might not be cached when
   using the "keepalive" directive.

*) Bugfix: a socket leak might occur when using the "error_page"
   directive to redirect early request processing errors, notably errors
   with code 400.

*) Bugfix: the "return" directive did not change the response code when
   returning errors if the request was redirected by the "error_page"
   directive.

*) Bugfix: standard error pages and responses of the
   ngx_http_autoindex_module module used the "bgcolor" attribute, and
   might be displayed incorrectly when using custom color settings in
   browsers.
   Thanks to Nova DasSarma.

*) Change: the logging level of the "no suitable key share" and "no
   suitable signature algorithm" SSL errors has been lowered from \ 
"crit"
   to "info".

directives
   in the "upstream" block.
*) Bugfix: the ngx_http_dav_module did not truncate destination file
   when copying a file over an existing one with the COPY method.
*) Bugfix: the ngx_http_dav_module used zero access rights on the
   destination file and did not preserve file modification time when
   moving a file between different file systems with the MOVE method.
*) Bugfix: the ngx_http_dav_module used default access rights when
   copying a file with the COPY method.

request",
   "unsupported protocol", and "version too low" SSL errors \ 
has been
   lowered from "crit" to "info".
*) Bugfix: DNS requests were not resent if initial sending of a request
   failed.
*) Bugfix: the "reuseport" parameter of the "listen" \ 
directive was
   ignored if the number of worker processes was specified after the

   proxy server in front of nginx.
*) Bugfix: the "tcp_nopush" directive was always used on backend
   connections.
*) Bugfix: sending a disk-buffered request body to a gRPC backend might
   fail.

Changes with nginx 1.15.0:
*) Change: the "ssl" directive is deprecated; the "ssl" \

*) Change: now nginx detects missing SSL certificates during
   configuration testing when using the "ssl" parameter of the \ 
"listen"
   directive.

Log message:
nginx-devel: updated to 1.13.10

directive now
   allows writing arbitrary responses to a variable; the
