Ehsan Akhgari 451773ee5b Bug 803392 - Initial implementation of AudioParam; r=bzbarsky
This patch implements most of the semantics of AudioParam in a
templatized base class called AudioEventTimeline.  This is done in order
to make it possible to test this code from C++ without the need of
linking to libxul.  Basically we take everything that could depend on
libxul or is not suitable for a genertic implementation and put it in a
traits like type as a template argument.  Then the test creates mock
objects that conform to the argument interfaces, and tests the logic of
AudioEventTimeline.
