ba3d7bfcd8 Added 'blocking' option to pcps_acquisition_cc 
Using C++ 11 threading routines to create a worker thread that can
perform the FFT for acquisition in a non-blocking manner. By default
'blocking' is set to true, which is identical to the previous behaviour
(with the added overhead of an extra thread). When 'blocking' is set to
false, then the main thread does not wait for the worker, thereby
letting the receiver continue even when the FFT thread is working. This
is very useful for using FFT acquisition at higher sampling rates, where
the FFT cannot be performed in real-time.

The aim is to replace the separate pcps_multithread_acquisition_cc.

TODO: implement the same thing for the pcps_acquisition_sc

2946d36f84 bugfix: Solves shared freq channel ambiguity and carr freq in plots 
Adds code to solve the shared frequency channels for GLONASS satellites
during acq and trk, it is now decode responsability to fix the identifier
when decoding of ephemeris happens. It also adds more details in tracking
plotting and fixes silly bug that created false alarm.

dc18980194 The global parameter name GNSS-SDR.internal_fs_hz has been replaced by 
GNSS-SDR.internal_fs_sps

The old name was misleading, since the units are samples per second and
not Hertz. 

Backward compatibility is kept, so this change does not break any
existing configuration.

0253f4ba05 Merge remote-tracking branch 'upstream/common_solver' into next 
This commit Integrates RTKLIB positioning libraries in a universal PVT
block implementation called RTKLIB_PVT. This results in an improved
positioning accuracy and precision with a wide range of options
(including Precise Point Positioning and ionospheric/troposphreic
models).

Not all the RTKLIB features have been ported. Some of them will be
progressively added. The ported options and how to configure them have
been documented in the website, see
http://gnss-sdr.org/docs/sp-blocks/pvt/

This commit also introduces a multi-band, multi system Observables block
implementation.

Relevant architectural changes that reduce latency and makes
multi-system, multi band signal handling easier.

Redundant blocks have been deleted. Old configurations are automatically
redirected to the new blocks for Observables and PVT, so the commit does
not break any existing configuration. The user should just notice a
relevant improvement in positioning performance.

8d8249247f Alternative fix for issue #31 
Rather than changing the index type to uint16_t, I think it would be
better to use the volk_32f_index_max32* functions instead of the 16 bit
counterparts. This ensures backwards compatibility (the index was
previously 32 bit, even if the function name indicated that it was 16
bit) and also, for FFT acquisition we may encounter large FFTs with more
than 65 535 points

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).

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
