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.

Added a generic tracking_loop_filter class
...
This implements a generic loop filter. Based on the analog PLL filters
from Kaplan and Hegarty, with a bilinear (Tustin's) transform from
s-plane to z-plane ( 1/s -> T/2 ( 1 + z^-1 )/( 1 - z^-1 ) )
Also added tests. Note the "truth" outputs
were derived from an Octave implementation of the loop filter and
Octave's builtin filter function

Added two Carrier_rotate correlator utilities
...
1) Carrier_rotate_and_EPL_volk
This is a very efficient VOLK based carrier wipeoff and
Early/Prompt/Late correlation. The carrier wipe off is done using the
VOLK rotator functions, which means there is no need to generate a local
replica sinusoid.
2) Carrier_rotate_and_VEPL_Volk
This adds Very Early/Early/Prompt/Late/Very Late correlation with the
VOLK rotator implementation of carrier wipe-off
