Inherit spdlog for GR 3.10 and log4cpp for lower GR versions. Inherit
both of these in the scope of the GR packages attribute set. Also use
the inherited log4cpp in qradiolink, gqrx & gnss-sdr.
Add some "3.9" attributes to srcs in gnuradio packages And update
packages using GR3.8 and that are incompatible yet with GR3.9 to use
GR3.8 explicitly.
- Write a `mkDerivation` and `mkDerivationWith` function for gnuradio,
like qt5.
- qradiolink, gqrx: Use gnuradio's callPackage and mkDerivation.
- Use gnuradio.callPackage to define all gnuradio.pkgs.
- Move all gnuradio packages expressions to pkgs/development/gnuradio-modules/ -
modeled after Python's.
- Add more paths to gnuradio's wrapper - add the extra packages as
python modules, and add their executables with proper env vars
wrapping.
