Summary:                    [patch] chan_dahdi deadlock heavy incomming traffic
Description: 
I had deadlocks ~ 2-3 hours on high incomming ss7 calls. The deadlock
happend after the answer.
After I moved ast_setstate(ast, AST_STATE_UP); in area where the pvt is
locked in dahdi_answer() (like in chan_sip), and protected from the double
answer, I have not more deadlocks.

Forget this, sorry. The problem was outside of dahdi...
It is seems stable. My system passed 160k calls within 1 week without any
failure
