Summary:                    Channel not locked when it should in
local_attended_transfer
Description: 
Right after performing the transfer, the target channel (target.chan1) is
unlocked. It is not locked again before performing the masquerade (although
aa comment says so).

Performing a relock of this channel leads to a deadlock with
&current->chan1. Trying to solve that deadlock led me to a bunch of astobj2
errors.
