07408cbd1f unix: Make micropython -m <module> work for frozen modules.
This requires some special handling, which was previosuly applied only to
the main code path.

4d9cad180d py: Implement implicit cast to obj for viper load/store index/value.
This allows to do "ar[i]" and "ar[i] = val" in viper when ar is a Python
object and i and/or val are native viper types (eg ints).

Patch also includes tests for this feature.

953c23b1bc py: Add stack check to mp_iternext, since it can be called recursively.
Eg, builtin map can map over a map, etc, and call iternext deeply.

Addresses issue #1294.

db52fd8e4d py: Wrap qstr defs in quotes to protect from C preprocessor.
This patch converts Q(abc) to "Q(abc)" to protect the abc from the
C preprocessor, then converts back after the preprocessor is finished.
So now we can safely put includes in mpconfig(port).h, and also
preprocess qstrdefsport.h (latter is now done also in this patch).

Addresses issue #1252.

79474c6b16 py: Remove unnecessary extra handling of padding of nan/inf.
C's printf will pad nan/inf differently to CPython.  Our implementation
originally conformed to C, now it conforms to CPython's way.

Tests for this are also added in this patch.

afaa66b657 py: Minor improvement to unichar_isxdigit
This drops the size of unicode_isxdigit from 0x1e + 0x02 filler to
0x14 bytes (so net code reduction of 12 bytes) and will make
unicode_is_xdigit perform slightly faster.

861670ba2a py: Implement mp_format_float for doubles and use where appropriate
This allows using (almost) the same code for printing floats everywhere,
removes the dependency on sprintf and uses just snprintf and
applies an msvc-specific fix for snprintf in a single place so
nan/inf are now printed correctly.

c50772d19f py: Add mp_obj_get_int_truncated and use it where appropriate.
mp_obj_get_int_truncated will raise a TypeError if the argument is not
an integral type.  Use mp_obj_int_get_truncated only when you know the
argument is a small or big int.

c2a4e4effc py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument.  Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.

This lead to quite a bit of code cleanup, and should be more efficient
if anything.  It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.

The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".

d5e629ad0e objgenerator: Can optimize StopIteration to STOP_ITERATION only if arg is None.
Unfortunately, MP_OBJ_STOP_ITERATION doesn't have means to pass an associated
value, so we can't optimize StopIteration exception with (non-None) argument
to MP_OBJ_STOP_ITERATION.

aa9dbb1b03 objgenerator: If generator yielded STOP_ITERATION value, it's stopped.
MP_OBJ_STOP_ITERATION is equivalent of raising StopIteration, except
mp_vm_return_kind_t for it is "yield".

a7c02c4538 vm: Null pointer test when checking for StopIteration optimizations.
When generator raises exception, it is automatically terminated (by setting
its code_state.ip to 0), which interferes with this check.

Triggered in particular by CPython's test_pep380.py.

4a60cac916 runtime: Add TODO for mp_resume() on handling .close().
Exceptions in .close() should be ignored (dumped to sys.stderr, not
propagated), but in uPy, they are propagated. Fix would require
nlr-wrapping .close() call, which is expensive. Bu on the other hand,
.close() is not called often, so maybe that's not too bad (depends,
if it's finally called and that causes stack overflow, there's nothing
good in that). And yet on another hand, .close() can be implemented to
catch exceptions on its side, and that should be the right choice.

4ed7b7f751 py: iternext() may not return MP_OBJ_NULL, only MP_OBJ_STOP_ITERATION.
Testing for incorrect value led to premature termination of generator
containing yield from for such iterator (e.g. "yield from [1, 2]").

37c6555b44 obj: Handle user instance hash based on Python adhoc rules.
User instances are hashable by default (using __hash__ inherited from
"object"). But if __eq__ is defined and __hash__ not defined in particular
class, instance is not hashable.

7667727021 objsingleton: New home for Ellipsis and NotImplemented.
Having NotImplemented as MP_OBJ_SENTINEL turned out to be problematic
(it needs to be checked for in a lot of places, otherwise it'll crash
as would pass MP_OBJ_IS_OBJ()), so made a proper singleton value like
Ellipsis, both of them sharing the same type.

5ab5ac5448 modbuiltins: Add NotImplemented builtin constant.
From https://docs.python.org/3/library/constants.html#NotImplemented :
"Special value which should be returned by the binary special methods
(e.g. __eq__(), __lt__(), __add__(), __rsub__(), etc.) to indicate
that the operation is not implemented with respect to the other type;
may be returned by the in-place binary special methods (e.g. __imul__(),
__iand__(), etc.) for the same purpose. Its truth value is true."

Some people however appear to abuse it to mean "no value" when None is
a legitimate value (don't do that).
