This means that complete slice operations are supported for lists (but not
for bytearray's and array.array's).

Older int-only encoding is not expressive enough to support arbitrary slice
assignment operations.

Addresses issue #598.

Now of the form MICROPY_PY_*.  See issue #35.

.makefile() should allow to specify which stream time to create - byte
or text.

Caveat is that __new__ should recurse to base class __new__, and ultimately,
object.__new__ is what handles instance allocation.

MP_ALLOC_* -> MICROPY_ALLOC_*
MICROPY_PATH_MAX -> MICROPY_ALLOC_PATH_MAX
MICROPY_ENABLE_REPL_HELPERS -> MICROPY_HELPER_REPL
MICROPY_ENABLE_LEXER_UNIX -> MICROPY_HELPER_LEXER_UNIX
MICROPY_EXTRA_* -> MICROPY_PORT_*

See issue #35.

Also, define object.__init__() (semantically empty, purely CPython compat
measure). Addresses #520.

Allow compilation of unix port under clang on OS X

See issue #608 for justification.

windows: Fix compilation with mingw-w64 so it uses correct printf implem...

Without this flag, mingw-w64 uses the MS implementations of snpintf and the likes.
This is not really a problem since they work with the the fixes provided for msvc,
but due to the way mingw-w64's stdio.h is structured we cannot get it to use the fixes.

io.FileIO is binary I/O, ans actually optional. Default file type is
io.TextIOWrapper, which provides str results. CPython3 explicitly describes
io.TextIOWrapper as buffered I/O, but we don't have buffering support yet
anyway.

Now case of subclassing tuple works, and list is broken, see comments.

Now schedule is: for native types, we call ->make_new() C-level method, which
should perform actions of __new__ and __init__ (note that this is not
compliant, but is efficient), but for user types, __new__ and __init__ are
called as expected.

Also, make sure we convert scalar attribute value to a bound-pair tight in
mp_obj_class_lookup() method, which avoids converting it again and again in
its callers.

Addresses issue #617.
