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

[Joshua Colp]

Joshua Colp has uploaded a new patch set (#5) to the change originally created by Guido Falsi. ( https://gerrit.asterisk.org/c/asterisk/+/10930 )

Change subject: chan_sip, chan_iax2, chan_pjsip: Allow updating variable values.
......................................................................

chan_sip, chan_iax2, chan_pjsip: Allow updating variable values.

When modifying an already defined setvar variable in chan_sip,
chan_iax2, and chan_pjsip drivers they add a new variable with
the same name instead of replacing the already existing variable.
This causes the old value to be used instead of the new one.

This change makes the code replace the old value with the new
one. The chan_dahdi driver already conforms to this, more logical,
behavior.

Support for setting channel variables on peers in chan_iax2
has also been added using the "setvar" option.
