centralize gdb command result class checking

each command can have only one of two legitimate responses: "error" or - depending on the command, and thus declared via a flag - "done" or "running". this is way nicer than sprinkling the code with else-ifs (where elses are sufficient) and asserts all over the place - and silently failing in release builds.
