adding AVX2 protokerns
...
I haven't found a way to do the rotator part better than with SSE3. Only
the dot product takes real advantage of 256-bit registers. Even tough,
the gain with respect to SSE3 is about 12%.

Adding new neon kernel and solving x86 issues

Managing memory with volk_gnsssdr instead of malloc and free. This seems

architectures.

Try another strategy based on multiply-and-accumulate for the dot
product. In all SIMD protokernels, managing memory with
volk_gnsssdr_malloc and volk_gnsssdr_free instead of calloc and free
