python: rename qemu.aqmp to qemu.qmp
Now that we are fully switched over to the new QMP library, move it back over the old namespace. This is being done primarily so that we may upload this package simply as "qemu.qmp" without introducing confusion over whether or not "aqmp" is a new protocol or not. The trade-off is increased confusion inside the QEMU developer tree. Sorry! Note: the 'private' member "_aqmp" in legacy.py also changes to "_qmp"; not out of necessity, but just to remove any traces of the "aqmp" name.
