A persistent failure that could lead to a session not being able to be
recovered, or a failure during the login process (which is not covered
by the recovery function), would normally cause the process to
terminate. This is expected when the configuration is run once, but not
desirable when running in daemon mode.
And thus just after the process has become a daemon, a session that
could not be restored, either because the connection to the server could
not be established or the login and its related negotiations failed, is
now disabled temporarily, and a recoqnection is attempted at the
beginning of the next daemon loop iteration.
There is one exception to that, and that is when there is an
authentication error, for example when a wrong username or password has
been supplied, and in this case the process terminates and a relevant
error is printed.
Instead of the account details, a pointer to the C structure is used in
Lua, stored as light userdata.
The 1.x deprecated configuration format has been removed, partly due to
the above change, and partly because it has been included for long
enough now.
Correct forking inside the daemon function, correct the error messages
printed, and add two new options for controlling working directory
change and redirection of the standard file descriptors.
Move the source code to the src dir, the man pages to the doc dir, and
the example configuration files to the samples dir, and update all
relevant files to reflect the changes.
