9acc7e7a20 Replaced fix point NCO by VOLK phase rotator in CPU multicorrelator 
(around 5% faster).
This optimization is enabled at this time only in
Tracking_DLL_PLL_C_Aid. Sample config can be found in
gnss-sdr_Hybrid_byte_sim.conf

450728dfeb fix defect detected by coverity scan: rinex observables are printed if 
both GPS and Galileo observables are available. This avoids
dereferencing an iterator though it is already past the end of its
container (in case only one of them were available)

c8f7e08127 Updated all GPS and Galileo trackings for double floating point internal 
computations and bug fixes in the carrier phase accumulator.
(all, except Matlab-Simulink linked trackings)

26b18c19ee Added a generic tracking_loop_filter class 
This implements a generic loop filter. Based on the analog PLL filters
from Kaplan and Hegarty, with a bilinear (Tustin's) transform from
s-plane to z-plane ( 1/s -> T/2 ( 1 + z^-1 )/( 1 - z^-1 ) )

Also added tests. Note the "truth" outputs
were derived from an Octave implementation of the loop filter and
Octave's builtin filter function

518deb501a Added IF handling to acq and tracking 
Only GPS L1 CA DLL PLL tracking for now. Still experimental.

b95219dbc6 Added two Carrier_rotate correlator utilities 
1) Carrier_rotate_and_EPL_volk

This is a very efficient VOLK based carrier wipeoff and
Early/Prompt/Late correlation. The carrier wipe off is done using the
VOLK rotator functions, which means there is no need to generate a local
replica sinusoid.

2) Carrier_rotate_and_VEPL_Volk

This adds Very Early/Early/Prompt/Late/Very Late correlation with the
VOLK rotator implementation of carrier wipe-off

086118c4aa Improvements to gnss_flowgraph 
1) Fixed a bug in gnss_signal::compare

The signal string comparison was not correct.

2) Fix for gnss_flowgraph when satellites are specified

3) Better handling of acquisition in flow graph

Now PRNs are alternated amongst channels, so we don't get 'stuck' on a
particular PRN, and we don't miss out on PRNs that are assigned to
channels that come after a channel that is always in the acquisition state.

4) Added SYS.prns to config file.

Now we can specify which PRNs are available in the configuration, rather
than re-compiling. Particularly useful for debugging, or experimenting
with files where you already know which signals are present

5b9683baad Multiple changes pcps acquisition: including linear corr. 
Reduced zero_padding_factor in pcps acquisition

This was 16, I'm processing data at about 16MHz, this oversampling
factor caused memory allocation issues

Previously dump file name was not being read from the configuration

Added fix for non-zero IF in pcps_acquisition_cc

Added linear correlation to pcps acquisition.

positioning performande is good.
