4480c12d94 Added a non CFAR PCPS acquisition algorithm based on the estimation of
the post correlation noise floor. If enabled
(.Acquisition_1C.use_CFAR_algorithm=true) as an option in the
acquisition configuration, it allows setting more stable thresholds in
the presence of non-gaussian front-end noise (which is the usual
behavior of front-ends....)

5a716840ab tracking dll pll cAid can work now with gr_complex and cshort just
setting the data imput type in config file. All the internal receiver
signal chain can work in complex short for the first time. Speed
improvement using custom gnss-sdr volk kernels for cshort data input
types.

c2676ec491 Added missing includes (to be removed in future versions). Steps towards
the integration of new standalone kernels into volk_gnsssdr library.

286ee3b561 Integrating the RTCM printer
Now the Galileo E1 receiver generates RTCM messages 1045 (ephemeris) and
MSM7 / 1097 (observables). Parameters related to RTCM included in conf
files. The TCP/IP server can be activated by setting flag_rtcm_server to
true.

9acc7e7a20 Replaced fix point NCO by VOLK phase rotator in CPU multicorrelator
(around 5% faster).
This optimization is enabled at this time only in
Tracking_DLL_PLL_C_Aid. Sample config can be found in
gnss-sdr_Hybrid_byte_sim.conf

aed688f3b4 DLL/PLL and phase accumulator bug correction and verification almost
done. Still some outliers detected in PPP using RTKLIB but the
positioning performande is good.
