Also fix "*" imports.
The formatting of test arrays is not fixed for multiple spaces following
"," and other violations that are common in tests. To be precise, E241
and E201 are added to the errors that are excluded.

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.

Run the 2to3 ws_comma fixer on *.py files. Some lines are now too long
and will need to be broken at some point. OTOH, some lines were already
too long and need to be broken at some point. Now seems as good a time
as any to do this with open PRs at a minimum.

Now that Python < 2.6 is no longer supported we can use the errstate
context manager in places where constructs like
```
old = seterr(invalid='ignore')
try:
blah
finally:
seterr(**old)
```
were used.

Add `print_function` to all `from __future__ import ...` statements
and use the python3 print function syntax everywhere.
Closes #3078.

The new import `absolute_import` is added the `from __future__ import`
statement and The 2to3 `import` fixer is run to make the imports
compatible. There are several things that need to be dealt with to make
this work.
1) Files meant to be run as scripts run in a different environment than
files imported as part of a package, and so changes to those files need
to be skipped. The affected script files are:
* all setup.py files
* numpy/core/code_generators/generate_umath.py
* numpy/core/code_generators/generate_numpy_api.py
* numpy/core/code_generators/generate_ufunc_api.py
2) Some imported modules are not available as they are created during
the build process and consequently 2to3 is unable to handle them
correctly. Files that import those modules need a bit of extra work.
The affected files are:
* core/__init__.py,
* core/numeric.py,
* core/_internal.py,
* core/arrayprint.py,
* core/fromnumeric.py,
* numpy/__init__.py,
* lib/npyio.py,
* lib/function_base.py,
* fft/fftpack.py,
* random/__init__.py
Closes #3172

This should be harmless, as we already are division clean. However,
placement of this import takes some care. In the future a script
can be used to append new features without worry, at least until
such time as it exceeds a single line. Having that ability will
make it easier to deal with absolute imports and printing updates.

module. The fix should be good for Python >= 2.4 and used the following sed script:
s/\<failUnless\>/assertTrue/g
s/\<failIf\>/assertFalse/g
s/\<failUnlessEqual\>/assertEqual/g
s/\<failUnlessRaises\>/assertRaises/g

* _Domained/MaskedUnary/BinaryOperations: optimization by preventing the use of np.where and the calculation of domain.
Here's the catch: we're basically cheating. We force np.seterr(divide='ignore',invalid='ignore') before computing the results, then mask the invalid values (if any) and reset the corresponding entries in .data to the input. Finally, we reset the error status. This playing around with the error status may (or may not) fail in multi-thread. It's still faaar faster than computing the domain (especially _DomainSafeDivide) when the inputs are large...

: * fixed some corner cases of view
mrecords : * fixed view
: * got rid of _fieldmask for _mask
: * WARNING: setting ._mask no longer calls __setmask__ : BE CAREFUL.
: * prevent setting ._mask directly, as it screws up things: use .mask instead
test_subclassing : * clean up

Added numpy.testing.run_module_suite to simplify "if __name__ == '__main__'" boilerplate code in test
modules.
Removed numpy/testing/pkgtester.py since it just consisted of an import statement after porting SciPy r4424.
Allow numpy.*.test() to accept the old keyword arguments (but issue a deprecation warning when old arguments
are seen).
numpy.*.test() returns a test result object as before.
Fixed typo in distutils doc.
