optimization to bark_noise_median()
...side loops. Duh. Hopefully this will be fixed with the final OS X which will have something 2.95 based.
If this doesn't hurt performance on x86 or some other platform or have some other problem, could you please commit it?
Thanks!

minor psy.c modifications
...LS*sizeof(float *));
new (corrected) lines:
p->noisemedian=_ogg_malloc(n*sizeof(float));
p->noiseoffset=_ogg_malloc(n*sizeof(float));
p->tonecurves[i]=_ogg_malloc(P_LEVELS*sizeof(float));
3. modified bark_noise_median():
3/a: floating point based (new) style:
#define BIN(x) ((int)((x)*negFour))
#define BINdB(x) ((x)*negQuarter)
#define BINCOUNT (200*4)
#define LASTBIN (BINCOUNT-1)
