Issue Description
Imported from JIRA: https://issues-archive.asterisk.org/ASTERISK-30481
chan_console deadlocks when channels are hung up, due to the read thread being cancelled while it is holding locks.
This redoes the disconnection more cleanly to avoid using pthread_cancel and uncleanly terminating threads.
