Please update FAQ regarding verbosity

[Mikhail Ryazanov]

doc/FAQ.md still says to use -v for debugging:

sslh/doc/FAQ.md

Lines 15 to 27 in eb84c6a

 In general, if something doesn't work, you'll want to run 
 `sslh` with lots of logging, and the logging directly in 
 the terminal (Otherwise, logs are sent to `syslog`, and 
 usually end up in `/var/log/auth.log`). You will achieve 
 this by running `sslh` in foreground with verbose: 
  
 ``` 
 sslh -v 1 -f -F myconfig.cfg 
 ``` 
  
 Higher values of `verbose` produce more information. 1 is 
 usually sufficient. 2 will also print incoming packets used 
 for probing. 

but this has stopped working completely since v2.0:

sslh/ChangeLog

Lines 29 to 32 in eb84c6a

 New log system: instead of --verbose with arbitrary 
 levels, there are now several message classes. Each 
 message class can be set to go to stderr, syslog, or 
 both. Classes are documented in example.cfg. 

and results in an error:

sslhcfg: invalid option "-v"

Thus the FAQ must be updated accordingly.

And a question: is there now a simple way to increase verbosity ”in general”? Or for some kind of messages — for example, it is not clear whether setting --verbose-connections will have any effect on --verbose-connections-try and --verbose-connections-error, or each of them needs to be set explicitly to see all connection-related messages.

The man file also must be updated, as it still “documents” the -v option instead of all these --verbose-...:

sslh/sslh.pod

Line 9 in eb84c6a

 sslh [B<-F>I<config file>] [B<-t> I<num>] [B<--transparent>] [B<-p> I<listening address> [B<-p> I<listening address> ...]  [B<--tls> I<target address for TLS>] [B<--ssh> I<target address for SSH>] [B<--openvpn> I<target address for OpenVPN>] [B<--http> I<target address for HTTP>] [B<--xmpp> I<target address for XMPP>] [B<--tinc> I<target address for TINC>] [B<--anyprot> I<default target address>] [B<--on-timeout> I<protocol name>] [B<-u> I<username>] [B<-C> I<chroot>] [B<-P> I<pidfile>] [-v] [-i] [-V] [-f] [-n]
