Move the codec decode type checks to bytes/bytearray.decode().

Use faster PyUnicode_FromEncodedObject() for bytes/bytearray.decode().

Add new PyCodec_KnownEncoding() API.

Add new PyUnicode_AsDecodedUnicode() and PyUnicode_AsEncodedUnicode() APIs.

Add missing PyUnicode_AsDecodedObject() to unicodeobject.h

Fix punicode codec to also work on memoryviews.
