Review request for Asterisk Developers.


Summary
-------

It seams that in Asterisk privacy with PAI is not implemented correctly.

According to RFC 3325 when using privacy, FROM header should be set to anonymous at anonymous.invalid and PAI header should be set to caller num and name. The privacy is implemented by adding privacy: id header.
Now when we use pai and callpres=prohib in P-Asserted-Identity header we have something which is not correct to any rfc.
P-Asserted-Identity: "Anonymous" <sip:anonymous at anonymous.invalid>

What my patch does:
1) it adds Privacy header when PAI is used (values "none" or "id" depending on callpres)
2)
3) "sendrpid" configuration option have been expanded:
now it can have those values:

    no - nothing changed
    yes - rpid header is added, when call PRES=prohi, FROM header is not changed
    rpid - the same as yes
    pai - pai header is added, when call PRES=prohi, FROM header is not changed

NEW VALUES:

    rpid,trusted (NEW) - the same as yes
    rpid,untrusted (NEW) - rpid header is added, when call PRES=prohi, FROM header is chenged to anonymous at anonymous.invalid
    pai,trusted (NEW) - the same as pai
    pai,untrusted (NEW) - pai header is added, when call PRES=prohi, FROM header is chenged to anonymous at anonymous.invalid - as in RFC 3325


This addresses bug ASTERISK-19465.
