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

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

Reduced zero_padding_factor in pcps acquisition
This was 16, I'm processing data at about 16MHz, this oversampling
factor caused memory allocation issues

Added linear correlation to pcps acquisition.
