Default communication socket for saslauthd: docs vs reality

[Conrad Kleinespel]

Hello everyone,

I am reading in the documentation that the default communication socket
for saslauthd is: 
```
/var/run/saslauthd/mux
```

However, in practice, it seems like the default socket would be:
```
/var/state/saslauthd/mux
```

As per configure.ac:
```
if test "$with_saslauthd" = yes; then
  with_saslauthd="/var/state/saslauthd"
fi
```

Am I missing something here ?

The `SMakefile` file does seem to have `./configure ...
--with-saslauthd=/var/run/saslauthd` but I don't see this part of
`SMakefile` being used anywhere: I'm confused as to why.

Thanks for your help,

Best regards,
