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/.

f54bcbf099 py, unix: Make "mpconfig.h" be first included, as other headers depend on it.

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.

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.

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.

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.

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.

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.

08d075592f py: Fix bug with LOAD_METHOD; fix int->machine_int_t for small int. 
LOAD_METHOD bug was: emitbc did not correctly calculate the amount of
stack usage for a LOAD_METHOD operation.

small int bug was: int was being used to pass small ints, when it should
have been machine_int_t.

55baff4c9b Revamp qstrs: they now include length and hash.

qstrdefsport.h

cbd2f7482c py: Add module/function/class name to exceptions. 
Exceptions know source file, line and block name.

Also tidy up some debug printing functions and provide a global
flag to enable/disable them.

08335004cf Add source file name and line number to error messages. 
Byte code has a map from byte-code offset to source-code line number,
used to give better error messages.

20006dbba9 Make VM stack grow upwards, and so no reversed args arrays. 
Change state layout in VM so the stack starts at state[0] and grows
upwards.  Locals are at the top end of the state and number downwards.
This cleans up a lot of the interface connecting the VM to C: now all
functions that take an array of Micro Python objects are in order (ie no
longer in reverse).

Also clean up C API with keyword arguments (call_n and call_n_kw
replaced with single call method that takes keyword arguments).  And now
make_new takes keyword arguments.

emitnative.c has not yet been changed to comply with the new order of
stack layout.

66028ab6dc Basic implementation of import. 
import works for simple cases.  Still work to do on finding the right
script, and setting globals/locals correctly when running an imported
function.
