2ab93f2599 bugfix: Fixes bugs with units in GNAV Almanac decoding 
Forces conversion of semicircles to radians units  in some GNAV Almanac
parameters. In addition, adds safeguards in code to avoid invalid
slot number identification.

2946d36f84 bugfix: Solves shared freq channel ambiguity and carr freq in plots 
Adds code to solve the shared frequency channels for GLONASS satellites
during acq and trk, it is now decode responsability to fix the identifier
when decoding of ephemeris happens. It also adds more details in tracking
plotting and fixes silly bug that created false alarm.

778fa4f5f8 bugfix: Fixes bug for carrier frequency in pcps_acq for GLONASS 
The code fixes the computation of the carrier frequency for pcps
acquisition of GLONASS satellites by making it relative to the IF. Also
new plotting features are added to visualize results

dc18980194 The global parameter name GNSS-SDR.internal_fs_hz has been replaced by 
GNSS-SDR.internal_fs_sps

The old name was misleading, since the units are samples per second and
not Hertz. 

Backward compatibility is kept, so this change does not break any
existing configuration.

0253f4ba05 Merge remote-tracking branch 'upstream/common_solver' into next 
This commit Integrates RTKLIB positioning libraries in a universal PVT
block implementation called RTKLIB_PVT. This results in an improved
positioning accuracy and precision with a wide range of options
(including Precise Point Positioning and ionospheric/troposphreic
models).

Not all the RTKLIB features have been ported. Some of them will be
progressively added. The ported options and how to configure them have
been documented in the website, see
http://gnss-sdr.org/docs/sp-blocks/pvt/

This commit also introduces a multi-band, multi system Observables block
implementation.

Relevant architectural changes that reduce latency and makes
multi-system, multi band signal handling easier.

Redundant blocks have been deleted. Old configurations are automatically
redirected to the new blocks for Observables and PVT, so the commit does
not break any existing configuration. The user should just notice a
relevant improvement in positioning performance.
