Revert r1506 (we actually are generating columns with the IDCT, so the naming makes sense in retrospect); further de-confusification in the forward DCT

Document the fact that the AltiVec implementation uses the same modified algorithms as the SSE2 implementation

Use intrinsics for loading/storing data in the DCT/IDCT functions. This has no effect on the performance of the aligned loads/stores, but it makes it more obvious what that code is doing. Using intrinsics for the unaligned stores in the inverse DCT functions increases overall decompression performance by 1-2%.

Split AltiVec algorithms into separate files for ease of maintenance; Rename constants using lowercase so they are not confused with macros
