  Improve support for media paths that can generate multiple frames at once.
  
  There are various media paths in Asterisk (codec translators and UDPTL, primarily)
  that can generate more than one frame to be generated when the application calling
  them expects only a single frame. This patch addresses a number of those cases,
  at least the primary ones to solve the known problems. In addition it removes the
  broken TRACE_FRAMES support, fixes a number of bugs in various frame-related API
  functions, and cleans up various code paths affected by these changes.
