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"

partially reverted change that generally checked for None on object indexing - seems to trigger crashes in Py3.2 for some reason

disable GIL check on NoneCheckNode to avoid unnecessary output cluttering - if it fails, the operation it guards will (normally) also fail

minor code cleanups in metaclass utility code, fix compiler warning about unused function __Pyx_Py3MetaclassGet()

even when 'boundscheck' is disabled or indexing is trivial, call PyUnicode_READY() during unicode indexing to comply with C-API constraints

removed outdated dummy assignment code that originally prevented an unsed argument gcc warning for __pyx_self, fix one more case where __pyx_self needs to be marked as unused
