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

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

Reduced zero_padding_factor in pcps acquisition
This was 16, I'm processing data at about 16MHz, this oversampling

...
This is a generic gnuradio block for handling 2 bit samples packed into
bytes or shorts. It can handle big or little endian ordering of the
samples within the byte, as well as big or little endian ordering of the
bytes within a short.
This is a utility function for a generic sample source which will be
able to handle all of these cases for both real and complex signals.
