Needed to pop the iterator object when breaking out of a for loop. Need also to be careful to unwind exception handler before popping iterator. Addresses issue #635.

This patch simplifies the glue between native emitter and runtime, and handles viper code like inline assember: return values are converted to Python objects. Fixes issue #531.

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/.

Implements 'def f(*, a)' and 'def f(*a, b)', but not default keyword-only args, eg 'def f(*, a=1)'. Partially addresses issue #524.

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.

Closed over variables are now passed on the stack, instead of creating a tuple and passing that. This way memory for the closed over variables can be allocated within the closure object itself. See issue #510 for background.

Attempt to address issue #386. unique_code_id's have been removed and replaced with a pointer to the "raw code" information. This pointer is stored in the actual byte code (aligned, so the GC can trace it), so that raw code (ie byte code, native code and inline assembler) is kept only for as long as it is needed. In memory it's now like a tree: the outer module's byte code points directly to its children's raw code. So when the outer code gets freed, if there are no remaining functions that need the raw code, then the children's code gets freed as well. This is pretty much like CPython does it, except that CPython stores indexes in the byte code rather than machine pointers. These indices index the per-function constant table in order to find the relevant code.

Improved the Thumb assembler back end. Added many more Thumb instructions to the inline assembler. Improved parsing of assembler instructions and arguments. Assembler functions can now be passed the address of any object that supports the buffer protocol (to get the address of the buffer). Added an example of how to sum numbers from an array in assembler.

Very little has changed. In Python 3.4 they removed the opcode STORE_LOCALS, but in Micro Python we only ever used this for CPython compatibility, so it was a trivial thing to remove. It also allowed to clean up some dead code (eg the 0xdeadbeef in class construction), and now class builders use 1 less stack word. Python 3.4.0 introduced the LOAD_CLASSDEREF opcode, which I have not yet understood. Still, all tests (apart from bytecode test) still pass. Bytecode tests needs some more attention, but they are not that important anymore.

Mostly just a global search and replace. Except rt_is_true which becomes mp_obj_is_true. Still would like to tidy up some of the names, but this will do for now.

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.

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.
