Summary:                    [patch] Asterisk runs over end of buffer reading
manager input over HTTP and segfaults
Description: 
We have a number of applications working over manager, and whilst I have
not been able to nail down what precisely is causing this, it has occurred
a number of times.  It looks like xml_translate is looking for a
null-terminated string, but the string is not always null-terminated, so it
runs off the end of the buffer and segfaults.

  Manager output is not always NULL-terminated, so force a NULL at the end
of the filestream.
