And the codec name is normalized.

Redecode the filenames of:

 - all modules: __file__ and __path__ attributes
 - all code objects: co_filename attribute
 - sys.path
 - sys.meta_path
 - sys.executable
 - sys.path_importer_cache (keys)

Keep weak references to all code objects until initfsencoding() is called, to
be able to redecode co_filename attribute of all code objects.

now conforms to the philosophy of bytes and unicode separation in Python 3.
A test suite has also been added.

r85073 changed the importing in wintypes to not use *, so the previous
usage here became even more incorrect.

 * Convert unicode to wide character string before creating the PyCapsule
   object
 * Catch integer overflow
 * Avoid useless memset()
 * Prepare the support of surrogates

Allocate memory with PyMem_Alloc() instead of the PyBytes API. Prepare the
surrogates support.

It simplifies the code and prepare the surrogates support.

Don't truncate path if it is too long anymore, and allocate fewer memory (but
allocate it on the heap, not on the stack).

Use the same behaviour than Python 2.7.

retry the select() loop instead of bailing out.  This is because select()
can incorrectly report a socket as ready for reading (for example, if it
received some data with an invalid checksum).

Closes issue #7397.

DeleteKeyEx, and OpenKeyEx.

Note that CKE and DKE are new functions for 3.2 so I didn't give them a
versionchanged because of the existing versionadded. OpenKeyEx already
existed so it gets a versionchanged tag.
