Make Store::buildPaths return a Status with [[nodiscard]] rather than throwing exceptions to signal failure. This is the beginning of a long road to refactor the entire store API to be status/statusor based instead of using exceptions.

2020-08-14 r/1646 refactor(tvix): completely remove boehm gcKane York15-170/+51
We have decided that leaking memory is a better fate than random, non-debuggable memory corruption. Future CLs will begin changing various fields to std::unique_ptr and std::shared_ptr. It turns out that disabling the GC does not have disasterous impact. The Nix evaluator only runs on the client CLI, never in any long- running process. Even the REPL does not leak too badly under this change, because it uses one EvalState for the duration of the REPL. Building an explicitly tracing garbage collector is likely in the future of this project, but that giant amount of work cannot be done under a nix evaluator that is constantly crashing. We need to restore development velocity here, and this is the best way we've figured out to do it.

2020-08-03 r/1557 refactor(3p/nix): Only initialise garbage-collector where neededVincent Ambo6-70/+72
Only libexpr depends on the garbage collector, specifically only instantiations of EvalState actually require the GC to be initialised. Rather than always starting it for the whole program, even if it is not needed, this change moves the GC initialisation into libexpr, guarded by absl::call_once. This should make it possible to run the nix daemon without the garbage collector interfering, granted that things are correcty separated and the daemon does not actually invoke the evaluator. Based on my investigation so far, the daemon logic itself does not require libexpr to be present at all - so I think it is safe - but the current monobinary might have some tricks up its sleeve that will cause problems for us. We can deal with those if they arise.
