This patch does the noisy work of removing the test opcodes from the exported interface to an interface that is only visible in `libc`. The benefit of this is that we both test the exported RPC registration more directly, and we do not need to give this interface to users. I have decided to export any opcode that is not a "core" libc feature as having its MSB set in the opcode. We can think of these as non-libc "extensions".
