db938bb047 Build fix due to a change in the gr-iio v0.3 API
A change in the API has removed the decimation parameter from sources
(see https://github.com/analogdevicesinc/gr-iio/issues/15 )

This commit fixes the build against the current master of
https://github.com/analogdevicesinc/gr-iio but it breaks compatibility
with older versions. Users with gr-iio already installed will need to
update it.

to the configuration file, if using gr-osmosdr >= 0.1.4-13

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.
