38e8feefa8 Name change in new DLL PLL algorithm implementation. We introduce DLL 
PLL Carrier Aided Tracking.

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

322550e0c6 Adding an option to build the binary without detecting the SIMD

072d0cad67 Important bug found and fixed: 
Volk memory alignement for signal vectors was using a hardcoded 16 bytes
value. This parameter is machine-dependant and thus, in modern machines
caused memory exceptions if the parameter not match.

All posix_memalign functions are now replaced by the GNU Radio
volk_malloc(vector_size (bytes), volk_get_alignement());

volk_get_alignement() returns the number of bytes to align the memory
blocks in the current processor.

The memory bug showed up when the receiver is configured with higher
sample rates (>4 Msps!)
