The main purpose of this branch is to explore avoiding the `usingnamespace` feature of the zig language, specifically with regards to `std.os` and related functionality. If this experiment is successful, it will provide a data point on whether or not it would be practical to entirely remove `usingnamespace` from the language. In this commit, `usingnamespace` has been completely eliminated from the Linux x86_64 compilation path, aside from io_uring. The behavior tests pass, however that's as far as this branch goes. It is very breaking, and a lot more work is needed before it could be considered mergeable. I wanted to put a pull requset up early so that zig programmers have time to provide feedback. This is progress towards closing #6600 since it clarifies where the actual "owner" of each declaration is, and reduces the number of different ways to import the same declarations. One of the main organizational strategies used here is to do namespacing with real namespaces (e.g. structs) rather than by having declarations share a common prefix (the C strategy). It's no coincidence that `usingnamespace` has similar semantics to `#include` and becomes much less necessary when using proper namespaces.
