[Asterisk-code-review] channels/chan pjsip: fix deadlock in response retransmissions (asterisk[13])

[Torrey Searle]

Hello Richard Mudgett, Jenkins2, George Joseph, Joshua Colp, 

I'd like you to reexamine a change. Please visit

    https://gerrit.asterisk.org/9477

to look at the new patch set (#8).

Change subject: channels/chan_pjsip: fix deadlock in response retransmissions
......................................................................

channels/chan_pjsip: fix deadlock in response retransmissions

The tdata containing the response can be shared by both the dialog
object and the tsx object.  In order to prevent the race condition
between the tsx retransmission and the dialog sending a response, cancel
the retransmission timer before sending a new response.
