Solomon Peachy 55eb1c54eb FS#7704 - Talk support for plugins
Original patch by Mario Lang
Heavily updated by Igor Poretsky
Further updated by myself

  This patch breaks binary API compatibility by placing the new
  functions where they make the most logical sense. IMO this is
  the better approach to take given the scope of the changes needed
  for talk support.

  Since binary API is changing, the patch also moves some other
  functions around to more logical locations.

  As well as voice support in plugins, this patch voice-enables several
  simple plugins.  There will be follow-up patches for many plugins that
  build on this one.
