This change introduces a fixpoint, which allows to do deep override when building packages defined in pkgs/development/beam-modules/default.hex. This allows to provide beam.packages.erlang{,R16,R17,R18,R19} which contains the same packages built with different Erlang/OTP versions. Top-level attribute beamPackages points at beam.packages.erlangR18, the same applies to other top-level Erlang packages. TODO: - beam.packages.erlang{R16,R17} is almost useless, since rebar/rebar3 does not build using these versions; - all packages in beam.packages which use buildMix are actually built with erlangR18; - update documentation.
