Damien George 04b9147e15 Add license header to (almost) all files.
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.

Damien George 968bf34c4c py: Remove unnecessary LOAD_CONST_ID bytecode.
It's the same as LOAD_CONST_STR.

Damien George 5f6a25fc50 py: Wrap #if's around emitter functions that are used only by emitcpy.
3 emitter functions are needed only for emitcpy, and so we can #if them
out when compiling with emitcpy support.

Also remove unused SETUP_LOOP bytecode.

Damien George 729f7b42d6 py: Merge BINARY_OP_SUBSCR and store_subscr (w/ delete) into subscr.
mp_obj_t->subscr now does load/store/delete.

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.

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
is not deleted twice.

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).

Damien George 1d24ea5207 py: Finish implementation of all del opcodes.
At this point, all opcodes are now implemented!

Some del opcodes have been combined with store opcodes, with the value
to store being MP_OBJ_NULL.

Damien George 523b575039 py: Add LOAD_NULL bytecode and use it to simplify function calls.
Adding this bytecode allows to remove 4 others related to
function/method calls with * and ** support.  Will also help with
bytecodes that make functions/closures with default positional and
keyword args.

Damien George 9aa2a527b5 py: Tidy up BINARY_OPs; negation done by special NOT bytecode.
IS_NOT and NOT_IN are now compiled to IS + NOT and IN + NOT, with a new
special NOT bytecode.

Damien George cbddb279bb py: Implement break/continue from an exception with finally.
Still todo: break/continue from within the finally block itself.

Paul Sokolovsky 90750029df Implement default function arguments (for Python functions).
TODO: Decide if we really need separate bytecode for creating functions
with default arguments - we would need same for closures, then there're
keywords arguments too. Having all combinations is a small exponential
explosion, likely we need just 2 cases - simplest (no defaults, no kw),
and full - defaults & kw.

Damien d99b05282d Change object representation from 1 big union to individual structs.
A big change.  Micro Python objects are allocated as individual structs
with the first element being a pointer to the type information (which
is itself an object).  This scheme follows CPython.  Much more flexible,
not necessarily slower, uses same heap memory, and can allocate objects
statically.

Also change name prefix, from py_ to mp_ (mp for Micro Python).
