The error occurs When values above 0x7FFFFFF are passed to a function
accepting "unsigned int".

This a port of a fix in pyprimtype.swg from which several code snippets
where copy pasted into swig/pyfragments.swg.

2015-12-23: ahnolds  [Python] Fixes for conversion of signed and
unsigned integer types ...

We are having problems running one of the wheels tests, so try
dropping Python 3.2 tests that cause problems with newer versions.

The virtualenv packatge has upgraded the setuptools that are installed
by default and this leads to pip failures due to failing wheels install.

Because of various back compatibility problems with relaxed stride
checking, make NPY_RELAXED_STRIDE_CHECKING=0 the default for the v1.11.0
release. See pull request #6684 and issue #6678 for discussion.

Also remove all mentions of setupegg.py from the documentation.

matches windows compiler behavior

Cython generated C code contains the number '-2147483648L', which
leads to a warning on 32 bit platforms:

"Warning: this decimal constant is unsigned only in ISO C90"

See the discussion at http://stackoverflow.com/questions/9941261/

The compiled code seems to run correctly despite the warning and
if there are problems, they should turn up in the nose testing.

Closes gh-6863.
