===== Immediate short term goals (from a conversation with my mentor) =====
  * <del>Add stubs which return EINVAL.</del>
    * <del>Document current knowledge about these in comments.</del>
  * Cleanup, refactor.
  * <del>Move code/includes to correct places.</del>
  * <del>Ditch the OSSV4_EXPERIMENT #ifdefs with exception of stubs.  (Comments must indicate why functions are inside the #ifdef and tell users not to enable it)</del>
  * Determine if man pages need updating & do so.
  * Either
    * "think if you can change the mixer to use the existing new stable stuff and change it if possible"
    * "push the new stable stuff down into the drivers where appropriate (the channel based mixer stuff IIRC)"

===== Misc =====
  * Look into channel alllocation, mapping between channels and device nodes.
