[Asterisk-code-review] translate: Provide translation modules the result of SDP neg... (asterisk[13])

[Alexander Traud]

Alexander Traud has uploaded a new change for review.

  https://gerrit.asterisk.org/1599

Change subject: translate: Provide translation modules the result of SDP negotiation.
......................................................................

translate: Provide translation modules the result of SDP negotiation.

Previously, a trancoding module did not have access to the joint but cached
format. Therefore, the module did not have access to the attributes negotiated
via SDP (line fmtp). Now, a translation module receives the joint format.
