Add aligned memory allocation to LAL
Update lal/packages/tools to use aligned memory
Fix mispelled aligned realloc function call in lal/packages/tools
Modify FFTW wrappings to allow aligned memory when configured
Fix broken XLALAlignedCalloc
aligned memory support for fftw3

This contains new XLALMallocAligned and similar routines for producing
aligned memory.  Presently they require posix_memalign so they are only
produced when LAL is configured with the appropriate fftw3 memalign option.

Floating point sequences then have aligned memory.  The FFT routines
use fftw3 optimizations for aligned memory.
Added Intel MKL FFT routines
Exclude nans from plot limits
