58b280afb6 Switch to GNU Radio 3.7.x API

3e87d1f204 Major update: 
- The GNSS-SDR code-based Observable generation algorithm for GPS L1 C/A was migrated from common TX time to common RX time. One of the main reasons is that the common TX algorithm was incompatible with the standard RINEX observables, wich requires the oservables at the same time of reception.
- Using common Rx time, the code was simplified and now requires less memory due to the lack of symbol buffer

- Now it is possible to use standard RINEX post processing software (gpstk and rtklib for instance) to get PVT and the obtained precision is comparable to the internal Least Squares solver. It is possible to use also the carrier phase observable, but is still experimental.

- The default RINEX version output was set to 2.11 in this revision.  RINEX 3.00 is under verification now.

09c6ac095a Adapting the configuration files: gnss-sdr.conf and gnss-sdr_gn3s_realtime.conf to the new features of the receiver (now, the calculation of acquisition threshold is made from the probability of false alarm). 
Fixed a little bug in channel.cc

e6dfa1971d Simplifying the configuration file: 
- Some channel and acquisition properties are now common for all channels
- You can choose between channel-specific properties or properties common to all
- Updating config file with the new options

e728450192 New feature (FE01): RINEX v 2.11 now outputs the following observables: 
PSEUDORANGE
CARRIER PHASE
CARRIER DOPPLER
SIGNAL STRENGTH (dB-Hz)

thus, it enables the realtime kinematics and PPP positioning for first time in an open source GNSS SDR. Enjoy!

0bf9e44eb4 SUPL assistance support in progress: 
- New SUPL parameters available in GNSS-SDR.conf
- Ephemeris assistance for real-time operation is now functional
- SUPL client now stores the received ephemeris in XML file. This file can be loaded on request to enable post-processing SUPL assistance and to enable SUPL assistance without internet connection. -> thowards a complete warm start GNSS-SDR.

BUG FIXES:
- GN3S driver firmware file copy operation in CmakeLists.txt had an error that mismatches the gn3s_firmware.ihx file location and prevents the correct firmware loading for GN3S SiGe USB dongles.

8b2d21c1c9 Major changes: 
- Gps telemetry decoder and PVT now uses independent queues for ephemeris, iono, utc_model and almanac. The old gps_navigation_queue is now deprecated and it is removed from the implementation. This affect almost all the PVT and Rinex printer classes.
- Rinex printer class updated to use the new ephemeris, iono, utc_model objects
Bug fixes and correction:
- The pseudorange generation now is based on the computed TOW for each received symbol. The History_Shift computation become simplier in this way. This modification is also a solution for a bug where the pseudoranges became temporally invalid when the TOW is updated (that happen every 6 secons!)

201b446c47 Added build support for the GN3S dongle. If the variable GN3S_DRIVER is set, CMake automatically builds the gr-gn3s project, adds the gn3s_signal_source and links the corresponding library. There is no need to have gr-gn3s already installed. 
Example:
$ cd build
$ export GN3S_DRIVER=1
$ cmake ../
$ make
$ make install

The gr-gn3s project can be build and installed independently, for instance for using it as a source block in gnuradio-companion.

0760fa0f3e - New NCO library for carrier signal generation: Provides a fixed point optimized wrapper for GNU Radio fxp CORDIC and SSE2 floating point implementation ( sse_mathfunc.h implementation). The library is available as nco_lib.h 
- Updated Unit Test to benchmark all the current NCO implementations (./run_tests --gtest_filter=Cordic_Test.StandardCIsFasterThanCordic)

-Gps_L1_Ca_Dll_Pll_Optim_Tracking algorithm updated with new NCO library for carrier wipeoff and some other optimizations.
