Summary:                    ? in register= string breaks registration
Description: 
If you put '?' (w/o quotation) in register= string in sip.conf, asterisk
does not parse it properly.

One of my register= string has '?' in its password section, and asterisk
can't parse it properly. This does not affect other lines in sip.conf

The string I used is as bellow,

register =>xxx at xxx.com:abc!5j5?!9!:xxx at hostip/123

Does '?' have been used as some token? Maybe I did not get that. I am
pretty sure I haven't seen it in change.log or sip.conf.sample.

The registration strings have worked fine with version 1.4.2, 1.6.0, and
1.6.1.0.
