Most are non-user facing. 
Found using:
`codespell -d -q 3`

Add support for array.arrays of int64s or uint64s (type codes q/Q).

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

    * Fix self / other typecode compatibility check and add test

    * In CPython, PyErr_BadArgument() C-API function always raises an
      exception and returns zero

    * It is needed to add the `except -2` clause, so that the exception
      raised by PyErr_BadArgument() is not ignored

    * Additionaly, the `return -1` statement in array.extend() will have
      no effect, and hence is misleading, so it needs to be removed

Unfortunately cannot use default args in pxd file; I also wouldn't know how the two array functions could be added as methods to the array class.
Restored "inline" attribute for array creation function, it can be disabled with a \#DEF
Removed some unused/redundant attributes.
Moved selected comments to docstrings.
Replaced tabs w/spaces.

Support for Python array objects. Adapted from patch at http://trac.cython.org/cython_trac/ticket/314
Changes: reverted Py_MEM_Realloc to Py_Mem_Resize, due to warnings
removed inline keyword (not portable, and Py_LOCAL_INLINE causes warnings).
moved a C declaration to top of function to avoid "mixed declaration"
