this change is messy as whoever wrote the original code copied the GetBitContext instead of passing a pointer to it which has to be fixed for the above thing

Also make more things available to external programs like GET_UTF8, MKTAG etc.

calculate all coefficients for several orders during cholesky factorization, the resulting coefficients are not strictly optimal though as there is a small difference in the autocorrelation matrixes which is ignored for the smaller orders

  this will find the coefficients which minimize the sum of the squared errors,
  levinson-durbin recursion OTOH is only strictly correct if the autocorrelation matrix is a
  toeplitz matrix which it is only if the blocksize is infinite, this is also why applying
  a window (like the welch winodw we currently use) improves the lpc coefficients generated
  by levinson-durbin recursion ...

optionally (use_lpc>2) support iterative linear least abs() solver using cholesky
  factorization with adjusted weights in each iteration

compression gain for both is small, and multiple passes are of course dead slow
