Summary: functionality for 128-bit-aligned memory (against pd-0.41-4)

Initial Comment: This patch implements public functions for allocation of 128-bit aligned memory. For allocation of all signals and buffers within PD these functions are consequently used. 128-bit alignment can speed up vector calculations, esp. if used with SIMD (also with autovectorization techniques). The infrastructure has been part of devel_0_39 and has now been ported to vanilla pd.

This sounds like a very useful addition. I have one minor question about the patch implementation. It seems that it would be more manageable if the new functions had the same name as the originals, then the original and the optimized versions could be swapped for each other with a single #ifdef which could be controlled by a ./configure flag.

Is there some code where you don't want to use the aligned functions? Redefining the original names would automatically give all the externals aligned memory as well.
