[ruby/irb] Support seamless integration with ruby/debug
(https://github.com/ruby/irb/pull/575)
* Support native integration with ruby/debug
* Prevent using multi-irb and activating debugger at the same time
Multi-irb makes a few assumptions:
- IRB will manage all threads that host sub-irb sessions
- All IRB sessions will be run on the threads created by IRB itself
However, when using the debugger these assumptions are broken:
- `debug` will freeze ALL threads when it suspends the session (e.g. when
hitting a breakpoint, or performing step-debugging).
- Since the irb-debug integration runs IRB as the debugger's interface,
it will be run on the debugger's thread, which is not managed by IRB.
So we should prevent the 2 features from being used at the same time.
To do that, we check if the other feature is already activated when
executing the commands that would activate the other feature.
