Add AppStream metadata file: contrib/de.barton.ngircd.metainfo.xml

Remove outdated OpenBSD/NetBSD systrace.policy Systrace was removed from OpenBSD and NetBSD, so remove this (old and outdated?) configuration file from the ./contrib directory. See <https://en.wikipedia.org/wiki/Systrace>. Thanks to "michi" for pointing this out on #ngircd!

contrib/README: Add nglog.sh script to the list

contrib/ngindent.sh: Enhance and rename script Add more GNU indent options for better results, and add the ".sh" suffix to bring this script in line with the others in the contrib/ folder.

contrib/ngircd.logcheck: Add sample logcheck(8) rules

Documentation: Spelling fixes

Merge branch 'systemd' * systemd: ngircd.sock: explicitely bind to IPv4 and IPv6 addresses Show address and port of sockets passed-in by systemd(8) Check type of sockets passed-in by systemd(8) Adjust severity levels of some log messages New configuration option "IdleTimeout": exit daemon when idle Implement support for systemd(8) "socket activation" contrib/README: add more files

Implement support for systemd(8) "socket activation" This patch enables ngIRCd to work with listening sockets already initialized and passed-in by systemd(8) and hereby to support on-demand "socket activation". systemd(8) uses two environment variables to pass information about the sockets to ngIRCd, LISTEN_PID and LISTEN_FDS, and this mechanism only kicks in when both variables are set. In all other cases, and therefore in most installations out there, nothing changes at all. Please note: If socket activation is in effect, ngIRCd will not initialize any (other) soeckets on its own! All sockets must be configured in the systemd(8) socket unit configuration file in this case, see ./contrib/ngircd.socket for example. Probably it would be interesting to match passed-in sockets to configured listening sockets and to initialize all the remaining ones not already set up by systemd(8), but this is kept back for an other patch ...

contrib/README: add more files

Remove Anope "ngircd" protocol module patches Starting with Anope 1.9.8, the ngIRCd protocol module is included in the Anope distribution, so there's no longer any need to support our own (but now heavily outdated!) patches. Therefore remove them.

Add preliminary ngIRCd protocol module for Anope 1.9 See contrib/Anope/README and doc/Services.txt for more details and installation instructions!

New script contrib/platformtest.sh This script analyzes the build process of ngIRCd and generates output suitable for inclusion in doc/Platforms.txt.

Added start/stop script for Red Hat based distributions Script contributed by Naoya Nakazawa <naoya@sanow.net>.

Renamed contrib/ngircd.sh to contrib/ngircd-bsd.sh

Added ngindent.

Added start script for FreeBSD.
