cacti port improvements

[jul_bsd@…]

• include some mainstream patch vs known bugs
• set default path/settings to macports
• add user/group cactiuser
• add plist file instead of cron (#16969 )
• conf as examples and post-activate
• example web config for nginx
• review notes w indication to setup snmpd
• variants but need review for plugin: superlinks (easy test), weathermap, advancedping

ideally, I would want a full mac template include by default for localhost.

[jul_bsd@…]

• review
• use OtherJobEnabled in plist for dependency to mysql and net-snmp (the latter only if monitoring includes localhost but I suppose that's the normal case)
• port lint
• include a newsyslog template file for rotating log
• remove some implicit PREFIX

bug "Portfile: extra characters after close-brace"

[jul_bsd@…]

• as discussed on #43418, I added mysql variants. it's not enforced at all as cacti is only a web interface and will rely on which socket is declared in php.ini or server address.
• also enable superlinks variant but need review to do it in the best manner. once it's working, can review more complicated plugins & template
• the OtherJobEnabled in my plist is not working on my setup, I had to disable it. Can someone else give it a try?

I currently have a strange behavior with the poller task. It is supposed to execute as cacti user (515)

<dict>
    <key>Label</key>
    <string>com.macports.cacti</string>
    <key>Username</key>
    <string>cactiuser</string>
    <key>ProgramArguments</key>
    <array>
        <string>/opt/local/bin/php55</string>
        <string>-q</string>
        <string>/opt/local/share/cacti/poller.php</string>

but in my system.log, I got Permission denied error. files are owned by cactiuser which is normal

Apr 24 10:31:19 HOST com.apple.launchd.peruser.502[192] (com.macports.cacti[7162]): open("/opt/local/var/log/cacti/poller.log", ...): 13: Permission denied
Apr 24 10:31:19 HOST com.apple.launchd.peruser.502[192] (com.macports.cacti[7162]): open("/opt/local/var/log/cacti/poller_err.log", ...): 13: Permission denied

so why it is trying to execute as user 502 (gui user) ? there is only the sudo call to launchctl which could come from but even if I unload/load as root, it changes nothing I tried moving from LaunchAgents (which was working before) to LaunchDaemons dir but same too

[jul_bsd@…]

• move launchd script to LaunchDaemons
• global.php is the a possible config file (​http://www.network-weathermap.com/manual/0.97b/pages/install-cacti.html Getting started)
• plugins: start to make variants working: included superlinks by default

[jul_bsd@…]

• I think the permission problem is solved and a consequence of newsyslog rotating and creating new files as root
• mode line
• sha256
