Bug fix 5586 correctly removed the linefeed from sipserver output. However as
the server writes to stdout which is by default buffered this means that we
cannot guarantee that responses are being returned in a timely fashion.

In practice this can be perceived as extremely slow performance by the
self-check unit or a cease of functioning altogether (the unit timesout).

In practice reverting 5586 fixes this but as 5586 'does the right thing' this
is not a good solution. The proposed solution is that autoflush is specifically
set on the output filehandle, to ensure the response message is not buffered.

Note because of the nature of the problem it is hard to reproduce the bug
consistently,
