[Asterisk-code-review] chan_sip, chan_iax2, chan_dahdi: Allow updating variable value. (...asterisk[master])

[Guido Falsi]

Hello Benjamin Keith Ford, Friendly Automation, George Joseph, Sean Bright, Joshua Colp, 

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

    https://gerrit.asterisk.org/c/asterisk/+/10930

to look at the new patch set (#12).

Change subject: chan_sip, chan_iax2, chan_dahdi: Allow updating variable value.
......................................................................

chan_sip, chan_iax2, chan_dahdi: Allow updating variable value.

When modifying an already defined variable in chan_sip and chan_iax2
drivers they add a new variable with the same name to the linked
list, but that value is never used, only the first one found. This
patch makes the code replace the old value with the new one.
Document added support for setvar in chan_iax2.
