(I'll kill this redundancy soon), add some patches from pkgsrc.
This really needs testing on other architectures/platforms so we can
decide which patches from audio/mpg123 are actually needed.
Also, I *think* I used the right arguments for madvise(), but I'm
not 100% sure ...
This is definitely faster and more robust than 0.59r; for instance,
It can decode two simultaneous 128kbps stereo streams on a 486DX/133.
I could always use help extending the sun audio module for NetBSD,
too--though it seems to work well enough for starters.
