BUG: Fix handling of dependencies between libraries

compiling with numpy.distutils. For example, something like this will now
work as a configuration function:
def configuration():
config = Configuration()
config.add_library('mylib1', sources=['mylib1.f'])
config.add_library('mylib2', sources=['mylib2.f'], libraries=['mylib1'])
config.add_extension('pymodule', sources=['pymodule.c'],
libraries=['mylib2'])
return config
Arbitrary handling of dependencies between libraries is still not
supported, but this should make some basic cases work properly.

python3.5 uses --parallel instead of --jobs

Allow extensions using numpy.distutils to compile in parallel.
By passing `--jobs=n` or `-j n` to `setup.py build` the compilation of
extensions is now performed in `n` parallel processes.
Additionally the environment variable NPY_NUM_BUILD_JOBS is used as
the default value, if its unset the default is serial compilation.
The parallelization is limited to within the files of an extension, so
only numpy multiarraymodule really profits but its still a nice
improvement when you have 2-4 cores.
Unfortunately Cython will not profit at all as it tends to build one
module per file.

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.

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.

Revert "Introduce new options extra_f77_compiler_args and extra_f90_compiler_args to Configuration.add_extension. Configuration.add_library, and Extension. These options allow specifying extra compile options for compiling Fortran sources within a setup.py file."
This reverts commit 43862759384a86cb4a95e8adb4d39fa1522acb28.

- Add better support for C++ in numpy.distutils. Instead of munging the
C compiler command, build_clib and build_ext call the new
Compiler.cxx_compiler() method to get a version of the compiler suitable for
C++ (this also takes care of the special needs of AIX).
- If config_fc is specified in the Extension definition, merge that info
instead of replacing it (otherwise, the name of the Fortran compiler is
overwritten). This is done at the key level (ex., compiler options are
replaced instead of appended).
- clean up compiler.py a bit
- clean up linking in build_ext
