I guess people were just waiting to hear if/when the gdbtk patch
had been merged. But really we don't need to wait for that. Split
out the MI part from the part that actually gets rid of
deprecated_command_loop_hook, and resend the MI bits. Once both MI
and the gdbtk patches are in, resend the deprecated_command_loop_hook
bit saying
"hey, there are no users left, let's just garbage collect this.".

I may be missing something, as I don't see a need for this ...

... given mi_command_loop actually does nothing
with mi_version... If we actually need it for something, we
can extract it from the interpreter's uiout, with mi_version(uiout).
