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).

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

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.

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.

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.

Add quick impl for MP_BC_LOAD_CONST_BYTES which just creates qstr so far.
This is based on the fact that qstr so far behaves more like byte string
than like Unicode string (for example, "012"[0] returns 48 (int)).

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).
