Damien George 6ce4277551 py: Make all LOAD_FAST ops check for unbound local.
This is necessary to catch all cases where locals are referenced before
assignment.  We still keep the _0, _1, _2 versions of LOAD_FAST to help
reduced the byte code size in RAM.

Addresses issue #457.

Paul Sokolovsky 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".

Damien George 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).

Paul Sokolovsky e9db840480 py: Start implementing "struct" module.
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").

Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions  - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.

Damien George 2bf7c09222 py: Properly implement deletion of locals and derefs, and detect errors.
Needed to reinstate 2 delete opcodes, to specifically check that a local

Paul Sokolovsky a985b4593d objint: Implement int.from_bytes() class method and .to_bytes() method.
These two are apprerently the most concise and efficient way to convert
int to/from bytes in Python. The alternatives are struct and array modules,
but methods using them are more verbose in Python code and less efficient
in memory/cycles.

Damien George f4c9b33abf py: Remove DELETE_SUBSCR opcode, combine with STORE_SUBSCR.
This makes the runtime and object APIs more consistent.  mp_store_subscr
functionality now moved into objects (ie list and dict store_item).
