Some errors in the PowerDNS Recursor documentation

[egnun]

Hello, PowerDNS folks,

I found some errors in the documentation.

Environment

• Operating system: GNU+Linux
• Software version: 4.9.9
• luajit: 2.1.1707061634
• Software source:Operating system repository

The first errors are in the "The DNSName object":

1. In the very first codeblock it says:
   name2:chopoff() …
   that should be:
   name2:chopOff()…

2. Also, the print(…) statements don't seem to work
   I don't know, if I don't know enough about Lua or if I may have misconfigured something, but the print statements don't have an output in the logfile/journald.
   Replacing them with pdnslog(<stuff to print>) seems to work though.
   E.g. instead of
   print(myname:wirelength()) -- prints "17"
   just:
   pdnslog(myname:wirelength()) -- prints "17"

I've also found an error in the "Operating PowerDNS Recursor"

Here it says

"By setting logging.quiet to true …

There you are linking to the new YAML style settings, which is confusing, since it's the only time you do that.

I hope this helps.

P.S.: I would've submitted a PR with the fixes, but it seems, that you don't have your documentation in a public repo (like Nitrokey or Nextcloud have ;-)

1. Correct
2. Indeed, it us better to use pdnslog, as some supervisors like systemd tend to "hide" output.
3. Old stytle settings are on their way out, but I agree there should be some consistency in a page.
