2ff3d9d0b2 builtinimport: Set __path__ attribute ASAP as it's clear we have a package. 
This helps with handling "recursive" imports in sane manner, for example
when foo/__init__.py has something like "from foo import submod".

8f19317540 py: Remove useless implementations of NOT_EQUAL in binary_op's. 
I'm pretty sure these are never reached, since NOT_EQUAL is always
converted into EQUAL in mp_binary_op.  No one should call
type.binary_op directly, they should always go through mp_binary_op
(or mp_obj_is_equal).

With new order of evaluation of defaults, creating the tuple was done in
the wrong spot.

13d52df4c5 builtinimport: Set __path__ attribute on packages. 
Per https://docs.python.org/3.3/reference/import.html , this is the way to
tell module from package: "Specifically, any module that contains a __path__
attribute is considered a package." And it for sure will be needed to
implement relative imports.

a925cb54f1 py: Preprocess qstrdefs.h before feeding to makeqstrdata.py. 
This is alternative implementation of supporting conditionals in qstrdefs.h,
hard to say if it's much cleaner than munging #ifdef's in Python code...

6ea0e928d8 Revert "makeqstrdata.py: Add support for conditionally defined qstrs." 
This reverts commit acb133d1b1.

Conditionals will be suported using C preprocessor.

69b89d21b2 py: Change compile order for default positional and keyword args. 
This simplifies the compiler a little, since now it can do 1 pass over
a function declaration, to determine default arguments.  I would have
done this originally, but CPython 3.3 somehow had the default keyword
args compiled before the default position args (even though they appear
in the other order in the text of the script), and I thought it was
important to have the same order of execution when evaluating default
arguments.  CPython 3.4 has changed the order to the more obvious one,
so we can also change.

a5c82a8187 py: Convert some macros to inline functions (in obj.h). 
Also convert mp_obj_is_integer to an inline function.

Overall this decreased code size (at least on 32-bit x86 machine).

e22d76e73b py: Fix up object equality test. 
It regressed a bit after implementing float/complex equality.  Now it
should be improved, and support more equality tests.

a9ddd6d9df py: Simplify and improve mp_get_index. 
It has (again) a fast path for ints, and a simplified "slow" path for
everything else.

Also simplify the way str indexing is done (now matches tuple and list).

57e99ebc86 py: Add simple way of looking up constants in compiler. 
Working towards trying to support compile-time constants (see discussion
in issue #227), this patch allows the compiler to look inside arbitrary
uPy objects at compile time.  The objects to search are given by the
macro MICROPY_EXTRA_CONSTANTS (so they must be constant/ROM objects),
and the constant folding occures on forms base.attr (both base and attr
must be id's).

It works, but it breaks strict CPython compatibility, since the lookup
will succeed even without importing the namespace.

Previously, a failed malloc/realloc would throw an exception, which was

(exception throwing), hence this patch.
