[reSIProcate] DUM InviteSession state during Re-Invite

[Kovar, William (Bill)]

Jason,

When operating as a B2B, a 3rd party controller may want to put one of
the controlled parties on Hold. This involve a re-invite and shuffle.
The SBC I work with uses re-invites as a session refresh.

So if the B2B is in the process of re-invite(HOLD) and the SBC sends a
re-invite(session refresh) we have an uncontrollable glare condition.

What is desirable is to allow the refresh to finish (if it got there
first), and then allow the 3rd party Hold to execute. Hence the need to
know that a re-invite is in progress.

Conversely, if the Hold started first, we 491 the refresh and it comes
back. If we're no longer shuffling the Hold, we handle the refresh.
Otherwise we 491 again.
