5a73b4e047 Improve package reproducibility 
Packages using CMake often use file(GLOB ...) to retrieve a list of
source files. As this is based on readdir(), the resulting file list
is unsorted. A common use case is to pass this list directly to
add_executable or add_library. But as the order is unpredictable, the
binaries are not reproducible (because the order in which the objects
are linked will vary).

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.

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!)

- Updated all available trackings to generate the tracking_timestamp_secs taking into account the remainder code phase.
- Updated the telemetry decoder to track the number of symbol shifted from the preamble start symbol (to be used in observables).
- Updated observables to align the reference channel symbol with the corresponding symbols in the other channels and compute pseudorranges using the common transmission time algorithm.
- Updated PVT to independize the display output rate from the RINEX and KML log files. New options available in config file!
- Some minor improvements and code cleaning.

0d598a7188 Added implementation of plain cordic class in tracking/libs. Added a corresponding test. The implementation is slower than standard sin and cos implementations, so it is not used in the receiver. The test will fail otherwise, indicating that this should be used instead of standard functions.

69b8ac00dc - Major changes: 
- The executable file and the default configuration file is now changed from "./install/mercurio" and "./conf/mercurio.conf" to "./install/gnss-sdr" and "./conf/gnss-sdr.conf", respectively.
        - Configuration file structure changed to define in a single entry the internal sampling frequency (after the signal conditioner). NOTICE that this change affects the all the adapters (acquisition, tracking, telemetry_decoder, observables, and PVT). All the adapters are now modified to work with this feature.
        - Moved several in-line GPS L1 CA parameters (a.k.a magic numbers..) to ./src/core/system_parameters/GPS_L1_CA.h definition file.
        - Tracking blocks now uses DOUBLE values in their outputs.
        - Observables and PVT now are separated. PVT and their associated libraries are moved to ./src/algorithms/PVT
        - Temporarily disabled the RINEX output (I am working on that!)
        - GNSS-SDR screen output now gives extended debug information of the receiver status and events. In the future, this output will be redirected to a log file.

- Bug fixes:
        - FILE_SIGNAL_SOURCE now works correctly when the user configures GNSS-SDR to process the entire file.
        - GPS_L1_CA_DLL_PLL now computes correctly the PRN start values.
        - GPS_L1_CA_DLL_FLL_PLL now computes correctly the PRN start values.
        - Several modifications in GPS_L1_CA_Telemetry_Decoder, GPS_L1_CA_Observables, and GPS_L1_CA_PVT modules to fix the GPS position computation.

- New features
        - Tracking blocks perform a signal integrity check against NaN outliers before the correlation process.
        - Tracking and PVT binary dump options are now documented and we provide MATLAB libraries and sample files to read it. Available in ./utils/matlab" and "./utils/matlab/libs"
        - Observables output rate can be configured. This option enables the GPS L1 CA PVT computation at a maximum rate of 1ms.
        - GPS_L1_CA_PVT now can perform a moving average Latitude, Longitude, and Altitude output for each of the Observables output. It is configurable using the configuration file.
        - Added Google Earth compatible Keyhole Markup Language (KML) output writer class (./src/algorithms/PVT/libs/kml_printer.h and ./src/algorithms/PVT/libs/kml_printer.cc ). You can see the receiver position directly using Google Earth.
        - We provide a master configuration file which includes an in-line documentation with all the new (and old) options. It can be found in ./conf/master.conf
