This modified patch:
  - includes changes to the interp kernel missing from the initial
    patch: optimization (vectorization & unrolling) and freq-domain
    fftshifting.
  - Renames to fftshift<row> and fftshfit<col>,
  - adds a vsip_csl/memory_pool header to make the memory pool
    extension more cleanly accessible.

Ok to apply?
