This is a complete rewrite of the RTLIL-kernel-side bufnorm code. This is done to support inout ports and undirected connections as well as to allow removal of cells while in bufnorm mode. This doesn't yet update the (experimental) `bufnorm` pass, so to manually test the new kernel functionality, it is important to only use `bufnorm -update` and `bufnorm -reset` which rely entirely on the kernel functionality. Other modes of the `bufnorm` pass may still fail in the presence of inout ports or undirected connections.
