db321d1c2e Fixing missing phase increment in SIMD implementations 
After computing the rotation with SIMD instructions, we were not
incrementing the phase step, so the first iteration in the 'c region'
had the same phase than the last sample computed with SIMD instructions.
This commit fix the bux in SSE3 and NEON implementations

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

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.
