    ENH: add a 'return_counts=' keyword argument to `np.unique`

    This PR adds a new keyword argument to `np.unique` that returns the
    number of times each unique item comes up in the array. This allows
    replacing a typical numpy construct:
    
        unq, _ = np.unique(a, return_inverse=True)
        unq_counts = np.bincount(_)
    
    with a single line of code:
    
        unq, unq_counts = np.unique(a, return_counts=True)
    
    As a plus, it runs faster, because it does not need the extra
    operations required to produce `unique_inverse`.

  3. BLD: remove cython c source from git

    Instead generate at build time. The generated sources are still part of

    configuration.

    ENH: Ensure that repr and str work for MaskedArray non-ndarray bases

    For repr, use the name of the base class in output as "masked_<name>"
    (with name=array for ndarray to match the previous implementation).
    For str, insert masked_print_option in an ndarray view of the object
    array that is created for string output, to avoid calling __setitem__
    in the base class.  Add tests to ensure this works.

  1. ENH: avoid searching for __numpy_ufunc__ if its a basic python type

    Checking for the attribute is a very large bottlenecks for reductions.
    dtype, out, keepdims will often be basic python types so the check can
    be skipped.
    Also add a couple missing types to helper function _is_basic_python_type
    and move it into a header so it can be used in umath.

  2. ENH: intern the constant python strings

    Was always intended this way but not done due to a mistake in Python3
    fix. Speeds up dictionary lookups a bit as string comparisons can be
    skipped on hash collisions.
