When you build from an external path, compiler can't find convert.h
include, because it was specified relative to the current directory.
Change this to specify the include dit relative to the Makefile
location.

For good practice, use const specifier when applicable.

An errant shuffle register value used in complex-complex convolution
causes distorted correlation peak-to-average values for certain TSC
values. The error effect varies for different TSC sequences with the
most noticeable effect of degraded detection on TSC 1 and no effect on
TSC 7.

Similar to the existing Intel SSE cases, add support for NEON vector
floating point SIMD processing. In this case, use ARM assembly
directly as the NEON intrinsics do not generate preferential code
output.
Currently support NEON vectorized convolution and floating point
integer conversions.

Using non-SSE4.1 enabled architecture would cause undefined
reference to 'convert_si16_ps' call.

Move x86 specific files into their own directory as this
area is about to get crowded with the addition of ARM
support.
