Rewrite most ndarray docstrings: RST-reformat old and add new ones.
Rewrite most ndarray docstrings: RST-reformat old and add new ones.

Most of the docstrings are adapted from those of the functions in
core.fromnumeric. I edited the ndarray method docstrings to closely match
the function docstrings.

I didn't yet fix the discrepancy in ndarray.reshape and fromnumeric.reshape
docstrings re ValueError raising.
