Review request for Asterisk Developers and David Vossel.


Summary
-------

Many sip headers in many sip methods contain the ABNF structure
 name-andor-addr = name-addr / addr-spec
Examples include the to-header, from-header, contact-header, replyto-header, referto-header, referredby-header, and passertedid-header

At the moment chan_sip.c makes various different attempts to parse this name-andor-addr structure for each header type and for each sip method with sometimes limited degrees of success.

I here introduce a dedicated function for parsing the name-andor-addr ABNF structure that can be used irrespective of the specific method or header that contains the structure

(The function is also suited to parsing the name-addr ABNF structure without the addr-spec option. Examples in chan_sip.c include the recordroute-header, route-header, remotepartyid-header and diversion-header.)


This addresses bug 16708.
