d113835073 adding new kernel: volk_gnsssdr_32fc_x2_rotator_dot_prod_32fc_xn

751764343c 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%.

485a405bab Adding new neon kernel and solving x86 issues
Managing memory with volk_gnsssdr instead of malloc and free. This seems
to solve runtime problems (segmentation faults) in i386 (32 bit)
architectures.

883cf629d1 Adding new NEON protokernel
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
