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.

In some architectures (e.g. alpha, hppa, powerpcspe, m68k, sh4, sparc64, x32) the package gr-osmosdr is not available. So when the package is build with -DENABLE_OSMOSDR=ON, it breaks on the mentioned architectures. This is expected behaviour (it breaks because a required dependency is not found), but prevents from building the package on such architectures. This commit introduces a small change: when compilation is called with
cmake -DENABLE_OSMOSDR=ON -DENABLE_PACKAGING=ON ..
then, the compilation does not break if gr-osmosdr is not found.
This commit also fixes building when UHD is present but gnuradio-uhd is not (for instance, in hurd-i386)
Packages using CMake often use file(GLOB ...) to retrieve a list of
source files. As this is based on readdir(), the resulting file list
is unsorted. A common use case is to pass this list directly to
add_executable or add_library. But as the order is unpredictable, the
binaries are not reproducible (because the order in which the objects
are linked will vary).

New options ENABLE_GN3S, ENABLE_RTLSDR, ENABLE_OPENCL, ENABLE_ARRAY and
ENABLE_GPERFTOOLS, all set by default to OFF. Users can enable that
features by 'cmake -DENABLE_XXX=ON ../ '. OpenCL is now not used by
default since it was giving problems in some platforms. Old variables
(RTSDR_DRIVER, GN3S_DRIVER, RAW_ARRAY_DRIVER and DISABLE_OPENCL) are
still honored and can be used in the same way, but the new ENABLE_XXX
are recommended for the sake of more uniform naming. Main CMakeFile.txt
has been rearranged, putting options first, then searching for the
required libraries, and then the optional ones. If Gperftools is enabled
and found, binaries are linked to the tcmalloc and profiler libraries,
and using the adequate flags. Fixed building in Mac OSX if Armadillo and
OpenBLAS were not installed in the system.
