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.

This time, in mp_seq_cmp_bytes(). How many more cases are still lurking?

Done in generalized manner, allowing any stream class to be specified as
working with bytes.

stat() is bad function to use using FFI, because its ABI is largely private.
To start with, Glibc .so doesn't even have "stat" symbol. Then, layout of
struct stat is too implementation-dependent. So, introduce _os to deal
with stat() and other similar cases.

sep=None is TODO.

This should now have correct (and optimal) behaviour.

unix: Use standard return codes for main

py, unix: Add copyright for modules I worked closely on.

Addresses issue #610.

Debugging output for emit_glue now simplified so that the init and
deinit functions are no longer needed.

__debug__ now resolves to True or False.  Its value needs to be set by
mp_set_debug().

TODO: call mp_set_debug in unix/ port.

TODO: optimise away "if False:" statements in compiler.

When disabling these via mpconfigport.mk or on the commandline,
the correspoding build options are not set and the sources are not
built so the modules should not be added to the
MICROPY_EXTRA_BUILTIN_MODULES list since they are undefined.

Infra for counts of other types is there, need last mile to be implemented.
