[Asterisk-code-review] res pjsip/res pjsip callerid: NULL check on caller id name s... (asterisk[13])

[Kevin Harwell]

Hello Richard Mudgett, Jenkins2, Sean Bright,

I'd like you to reexamine a change.  Please visit

    https://gerrit.asterisk.org/5541

to look at the new patch set (#4).

Change subject: res_pjsip/res_pjsip_callerid: NULL check on caller id name string
......................................................................

res_pjsip/res_pjsip_callerid: NULL check on caller id name string

It's possible for a name in a party id structure to be marked as valid, but the
name string itself be NULL (for instance this is possible to do by using the
dialplan CALLERID function). There were a couple of places where the name was
validated, but the string itself was not checked before passing it to functions
like 'strlen'. This of course caused a crashed.

This patch adds in a NULL check before attempting to pass it into a function
that is not NULL tolerant.
