allowguest=yes be the default


At Tilghman's request.
 
We need to agree to change the sip.conf default from allowguest=yes to
allowguest=no
and extensions.conf to have a warning in the [default] section that sip.conf
may have allowguest=yes or nothing which will default of yes.
 
Reference mantis bugs;
 <https://issues.asterisk.org/view.php?id=15101>
https://issues.asterisk.org/view.php?id=15101 SIP allowguest defaults to yes
with 'make samples' 
 <https://issues.asterisk.org/view.php?id=16226>
https://issues.asterisk.org/view.php?id=16226 1.4.26.3 security issue -
Chinese IPs somehow are making calls without authentication 
 
There are many installations out there where newbies are playing in the
[default] context in their dialplan, getting things working, then opening
port 5060 in their firewall without understanding what they've just done.
 
Initially I thought it was great that we allow any SIP phone to connect to
asterisk, with no configuration required at the astrisk end, how wrong I
was.
