DOC: Warn when reloading numpy or using numpy in sub-interpreter
This adds a warning when the main NumPy module is reloaded
with the assumption that in this case objects such as `np.matrix`,
`np._NoValue` or exceptions may be cached internally.
It also gives a warning when NumPy is imported in a sub-interpreter.
