9e29666bf9 py: Implement proper separation between io.FileIO and io.TextIOWrapper. 
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.

Paul Sokolovsky
13684fd60b objtype: Separate __new__ and __init__ methods. 
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.

ee7a880d6e py: Use mp_arg_check_num in more places. 
Updated functions now do proper checking that n_kw==0, and are simpler

that the error messages no longer include the function name, but that's
acceptable.

Saves order 300 text bytes on x64 and ARM.

eea0118654 py: Give up and make mp_obj_str_get_data() deal with bytes too. 
This is not fully correct re: error handling, because we should check that

ea9708092e objtuple: Go out of the way to support comparison of subclasses. 
Two things are handled here: allow to compare native subtypes of tuple,
e.g. namedtuple (TODO: should compare type too, currently compared
duck-typedly by content). Secondly, allow user sunclasses of tuples
(and its subtypes) be compared either. "Magic" I did previously in
objtype.c covers only one argument (lhs is many), so we're in trouble
when lhs is native type - there's no other option besides handling
rhs in special manner. Fortunately, this patch outlines approach with
fast path for native types.

Parser shouldn't raise exceptions, so needs to check when memory

go there instead of on the heap.

d86020ac4f objtype: Don't treat inheritance from "object" as from native type. 
"object" type in MicroPython currently doesn't implement any methods, and
hopefully, we'll try to stay like that for as long as possible. Even if we
have to add something eventually, look up from there might be handled in
adhoc manner, as last resort (that's not compliant with Python3 MRO, but
we're already non-compliant). Hence: 1) no need to spend type trying to
lookup anything in object; 2) no need to allocate subobject when explicitly
inheriting from object; 3) and having multiple bases inheriting from object
is not a case of incompatible multiple inheritance.

a592104acd stream: Add compliant handling of non-blocking read()/write(). 
In case of empty non-blocking read()/write(), both return None. read()
cannot return 0, as that means EOF, so returns another value, and then
write() just follows. This is still pretty unexpected, and typical
"if not len:" check would treat this as EOF. Well, non-blocking files
require special handling!

This also kind of makes it depending on POSIX, but well, anything else
should emulate POSIX anyway ;-).
