Summary:                    [patch] T38 reinvite started from Asterisk
Description: 
If Asterisk starts reinvite for T38 it seems that no UPDTL frame are sent
over the chan_sip.
Asterisk sends reinvite and p->t38.state's value is T38_LOCAL_REINVITE but
when other peer send 200 OK in process_sdp function p->t38.state becomes
T38_PEER_REINVITE but in this case  p->t38.state will never be
T38_ENABLED.

Attached patch for chan_sip on asterisk 1.4.25.1 ,
I can confirm the issue.

Basically asterisk when checks sdp does not differentiate between
a reinvite sent by peer or by asterisk itself.
