[Build/Dependencies] added a comparision for setuptools.Extension class

This is done with the T=* syntax, similar to default args
of cdef methods.

This does, however, expose us to types that we can't
explicitly declare.

Optimize dependency checking

Ensure that extension's include_dirs is a list

This change allows to pass generator (e.g. itertools.chain) as
include_dirs if for some reason evaluation of include directories needs
to be delayed e.g. due to simultaneous dependency on cython and numpy.

Fix parse_list("")

Use correct macros to check GCC version

use slightly faster PyObject_Malloc() instead of PyMem_Malloc() for small memory allocation needs (<= 512 bytes)

Cpp iterator declarations.

Don’t crash when a C class isn’t defined in the pxd

Fix typo in numpy tutorial

Hide some parts of stack trace in __PYX_ERR macro

These were already failing when this was added to the build matrix.

Enable tests on python 3.5-dev
