[RFC] -mi-level command

["Alain Magloire" <alain@qnx.com>]

Bonjour

	Maybe there is a better way to do this, most clients of GDB/MI
need a way to know the level to adjust the parsing or go around bugs in
previous(or current version).

	One problem with the code below is that mi_version() is returning ..."3"

I'll be happy to provide docs etc .. after.
