More consistent naming
...
now volk_gnsssdr_16ic_xn_resampler_16ic implements the same resampler
than volk_gnsssdr_32fc_xn_resampler_32fc. The old one, which is faster
in SSE implementations at the expense of some constraints on the inputs
(to be documented), is now named
volk_gnsssdr_16ic_xn_resampler_fast_16ic

This fixes a runtime error, since VOLK functions are static and a
segmentation fault was caused when aligned and unaligned versions were
called concurrently.

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%.
