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.

---------------------------------------------------------------------- 
I think it's much more sane simply to NULL-terminate the file, before
mmap'ing it into memory.  Patch uploaded.
