8fd6b662b7 Added GNURadio 3.4.2 and Ubuntu 11.10 compatibility. Environment variable GNURADIO_330_ROOT is now generic GNURADIO_ROOT

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

34d1c5110b GNSS-SDR Major changes:
New tracking libraries:
        -  tracking_discriminators: Library with a set of code tracking and carrier tracking discriminators that is used by the tracking algorithms. (fully documented, including math algorithms using doxygen!)
        -  tracking_2rd_DLL_filter: Class that implements 2 order DLL filter for code tracking loop.
        -  tracking_2rd_PLL_filter: Class that implements 2 order PLL filter for carrier tracking loop.
        -  tracking_FLL_PLL_filter:  Class that implements hybrid FLL and PLL filter for tracking carrier loop.
        -  CN_estimators: Library with a set of Carrier to Noise estimators and lock detectors. (fully documented, including math algorithms using doxygen!)

    Tracking:
        - gps_l1_ca_dll_pll_tracking: The existing DLL + PLL tracking module, which is the K.Borre and D.Akos one, is now completely re-factored. Now uses the above described libraries.
        - gps_l1_ca_dll_fll_pll_tracking: This is a brand new tracking module, which implements the FLL assisted PLL described in Kaplan (2nd edition). (also documentedwith references)

    Configuration options:
        - The following tracking parameters are added:
            ;######### TRACKING CONFIG ############
            ; Tracking.implementation=GPS_L1_CA_DLL_PLL_Tracking or GPS_L1_CA_DLL_FLL_PLL_Tracking 
            Tracking.implementation=GPS_L1_CA_DLL_FLL_PLL_Tracking
            ;PLL filter bandwidth in Hz.
            Tracking.pll_bw_hz=50.0;
            ;DLL filter bandwidth in Hz.
            Tracking.dll_bw_hz=2.0;
            ;FLL filter bandwidth in Hz.
            Tracking.fll_bw_hz=50;
            ;filter order: choice between 2 or 3 at this moment, only for FLL assisted PLL
            Tracking.order=2;
            ;Correlator space in chips units
            Tracking.early_late_space_chips=0.5;

Other files have also been modified with minor changes to adapt to new modules or minor bug fixes.

004cd776d9 BUG FIX: Now the file_signal_source obeys the SignalSource.samples configuration parameter in the conf file. This fix allows limiting the number of samples to be processed by the receiver.

dcc3e4d858 Change of the set_doppler_freq_shift(float phase) to set_doppler_freq_shift(float doppler_freq_hz), and set_prn_code_phase(signed int phase) to set_prn_code_phase(signed int phase_samples), which are more appropiate, in tracking_interface. Minor changes in tracking adapters to be coherent with the new variable names
