[patch] Cleanup for release.

[Jules Bergmann]

This patch
  - fixes a bug with Rt_extdata incorrectly attempting to deallocate
    storage.
  - fixes a bug in the handling of column-major data for 2D and 3D
    FFTs with the FFTW3 backend.
  - adds checks on data layout for the 2D and 3D FFTW3 backends.
  - fixes the SAL FFTM backend to use the rows/cols of the data
    being processed to determine the number of FFTs to perform
    (as opposed to the size of the FFTM object when created).
    Necessary for distributed FFTMs.
  - Disables SAL's FFTM evaluator from trying to do long-double
    FFTMs
  - Cleans up fft.cpp test to make the ifdefs a little more manageable.

Patch applied.
