600ae734cf py: Implement break and continue byte codes, and add tests.
Also fixes a bug in the for-in-range optimiser.

I hope to remove break and continue byte codes in the future and just
use jump (if possible).

55baff4c9b Revamp qstrs: they now include length and hash.
Can now have null bytes in strings.  Can define ROM qstrs per port using
qstrdefsport.h

a80ff04fe7 Add dummy bytes() constructor.
Currently, MicroPython strings are mix between CPython byte and unicode
strings. So, conversion is null so far. This dummy implementation is
intended for compatibility with CPython (so, same code can run on both).

440cc3f028 Expose memory stats functions via "micropython" module.
These are micropython.mem_total(), .mem_current(), .mem_peak(). These are 3
individual functions with simple scalar return value to make sure that
calls to these functions themselves have minimal (hopefully zero) impact on
memory allocation.

d720ab5236 Implement modules as singletons Python semantics.
In Python, importing module several times returns same underlying module
object. This also fixes import statement handling for builtin modules.

There're still issues:
1. CPython exposes set of loaded modules as sys.modules, we may want to
do that either.
2. Builtin modules are implicitly imported, which is not really correct.
We should separate registering a (builtin) module and importing a module.
CPython keeps builtin module names in sys.builtin_module_names .

427905cedd Add skeleton implementation of array.array and bytearray.

implemented - alredy suitable for passing binary data around.

__add__, __sub__.  Easy to add others.

d26b379eec int: Add value accessors: mp_obj_int_get() & mp_obj_int_get_checked().
mp_obj_int_get() can be used when just full resolution of C machine_int_t
is required (returns truncated value of long int). mp_obj_int_get_checked()
will throw exception if Python int value not representable in machine_int_t.

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.
