HTTP/2: graceful shutdown of active connections (closes #1106). Previously, while shutting down gracefully, the HTTP/2 connections were closed in transition to idle state after all active streams have been processed. That might never happen if the client continued opening new streams. Now, nginx sends GOAWAY to all HTTP/2 connections and ignores further attempts to open new streams. A worker process will quit as soon as processing of already opened streams is finished.

# this script converts CSV geoip database (free download at http://www.maxmind.com/app/geoip_country)
# to format, suitable for use with nginx_http_geo module (http://sysoev.ru/nginx)
#
# for example, line with ip range
#
#   "62.16.68.0","62.16.127.255","1041253376","1041268735","RU","Russian Federation"
#
# will be converted to four subnetworks:
#
#   62.16.68.0/22 RU;
#   62.16.72.0/21 RU;
#   62.16.80.0/20 RU;
#   62.16.96.0/19 RU;
