Summary:                    [patch] chan_sip behaves like crazy if there is not
route to destination
Description: 
If the host asterisk is running has no routes to the registration server I
get continuous messages like below. In addition after ten minutes the
machine crashes due to no memory available (asterisk takes it all).

Remove harmful code that causes endless loops. 
Remove code that causes loops in registrations. 

We have agreed that the patch that this code was part of was bad. I am
ripping out the code that causes 
the issue. putnopvut needs to check the rest of the patch, if it needs to
be changed as well.

This solves the issue reported in https://issues.asterisk.org/view.php?id=15540,
but needs more work before we
close it (as described above).
