Garbage is printed for tel: URI in the URI parameter in Authorization/Proxy-Authorization header

[bennylp]

Garbage character will be printed if tel: URI is used in Authorization and Proxy-Authorization header. This is because the sip_auth_client.c relies on undocumented NULL termination in pjsip_uri_print(). Unfortunately the NULL termination was not added for tel: URI.

This ticket adds two fixes:

• remove the reliance on NULL termination in sip_auth_client.c
• add the NULL termination when printing tel: URI just in case other components use it

Thanks Bart Klin / Arkadiusz Wronski for the report.

Really fix #1609 after better understanding about the problem. This changeset:

• undo r4320
• remove the reliance on NULL termination in sip_auth_client.c
• add the NULL termination when printing tel: URI just in case other components use it
