Update to current nixpkgs-unstable This required the introduction of an overlay file since ofBorg still requires openssl 1.0.2. Updating to newer version of openssl also requires updating the amqp library which requires some more involved changes. The php code is only updated to php 7.2 and not 7.3 (the default in nixpkgs) since there seem to been a few syntax changes that aren't yet compatible with composer2nix. In previous versions of the rust infrastructure within nixpkgs we would have been able to override all crates during the invocation of the target crate. That `override` feature was removed as it caused a huge eval overhead for larger projects. We did end up with (n^2) instantiations of dependencies since they were being overriden on every invocation of every dependency on every level further down the chain. The current understanding is that the build tooling that each project is using (e.g. crate2nix, crate2nix, …) that is driving the actual build could easily reintroduce that feature without the overhead. pin to php72 2020-02-21 15:40:22 +00:00			`(self: super: {`
