Summary:                    Introduce function for parsing ABNF name-andor-addr
= name-addr / addr-spec
Description: 
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

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 recommend that this name-andor-addr structure be parsed by a dedicated
function and that it be used irrespective of the specific method or header
that contains the name-andor-addr structure

---------------------------------------------------------------------- 
I think that the function check_user_full gets the closest to doing a half
decent attempt at parsing the name-andor-addr abnf structure so as a first
step I will lift the relevant bits from this and drop them into a new
function parse_name_andor_addr using it only for check_user_full. I will
then try to enhance the new function to do a more accurate job of parsing
and ensure that it would be suitable for use in other places where parsing
of the name-andor-addr abnf structure is needed. Finally the use of the
function can be rolled out across chan_sip.c. I will try to get the first
step uploaded here soon but I understand if you need to close the ticket
