73e4ff9de9 Almost cosmetic changes in dsputil_init_ppc and vorbis_inverse_coupling_altivec: 
- whitespace consistency 2->4 [dsputil_init_ppc]
- reorder struct initialization with dsputil_init_altivec [dsputil_init_ppc]
- use casts instead of temp variables [vorbis_inverse_coupling_altivec]

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
