[Asterisk-code-review] pjsip: Match lifetime of INVITE session to our session. (asterisk[16])

[Joshua Colp]

Hello Sean Bright, George Joseph, Friendly Automation, 

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

    https://gerrit.asterisk.org/c/asterisk/+/15122

to look at the new patch set (#2).

Change subject: pjsip: Match lifetime of INVITE session to our session.
......................................................................

pjsip: Match lifetime of INVITE session to our session.

In some circumstances it was possible for an INVITE
session to be destroyed while we were still using it.
This occurred due to the reference on the INVITE session
being released internally as a result of its state
changing to DISCONNECTED.

This change adds a reference to the INVITE session
which is released when our own session is destroyed,
ensuring that the INVITE session remains valid for
the lifetime of our session.
