Log Message:
nginx-devel: updated to 1.13.10

1.13.10:
*) Feature: the "set" parameter of the "include" SSI \ 
directive now
   allows writing arbitrary responses to a variable; the
   "subrequest_output_buffer_size" directive defines maximum response
   size.

*) Feature: now nginx uses clock_gettime(CLOCK_MONOTONIC) if available,
   to avoid timeouts being incorrectly triggered on system time changes.

*) Feature: the "escape=none" parameter of the "log_format" \ 
directive.
   Thanks to Johannes Baiter and Calin Don.

*) Feature: the $ssl_preread_alpn_protocols variable in the
   ngx_stream_ssl_preread_module.

*) Feature: the ngx_http_grpc_module.

*) Bugfix: in memory allocation error handling in the "geo" directive.

*) Bugfix: when using variables in the "auth_basic_user_file" directive
   a null character might appear in logs.
