  * Removed all static local variables that were SAVE'd in the Fortran

  * argument.
  *
  * Removed init function, since all initialization is now done in
  * init_lpc10_encoder_state().
  *
  * Changed name of function from lpcenc_ to lpc10_encode, simply to make
  * all lpc10 functions have more consistent naming with each other.
