438ba45c16 Fix acquisition with rata rates higher than 16 Msps in 4ms code periods

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

24e62c4e4e Make use of volk_gnsssdr_malloc, volk_gnsssdr_free 
instead of volk_malloc, volk_free (which are missing from the volk
version distributed by ubuntu 14.04). Fix the include guard in
volk_gnsssdr_malloc.h 
Thanks to @hoernchen

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).

681bd60a58 Files to test an experiment performed by Luis Esteve in the framework of the Google Summer of Code (GSoC) 2012, with the collaboration of Javier Arribas and Carles Fernández, related to the extension of GNSS-SDR to Galileo. The objective is perform a positive acquisition of in-orbit Galileo signals in the E1 band.

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
