bc185f72c0 Do not crash when the first frame is not a keyframe (and thus none of the 
necessary initialization has been done yet).

e278056fba check how many bits are left after decoding extradata 
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

ab01b2b82a optionally (use_lpc=2) support Cholesky factorization for finding the lpc coeficients 
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
