0d028743aa py: Initialise loaded_module map in rt_init. 
STM port crashes without this re-init.  There should not be any state in
the core py/ code that relies on pre-initialised data.

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

4c316552c1 Implement str.split(None). 
Note that splitting by explicit string is not implemented so far.

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 .

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.

f49ba1bd9c Improve method lookup in mp_obj_class_lookup.

427905cedd Add skeleton implementation of array.array and bytearray. 
So far, only storage, initialization, repr() and buffer protocol is
implemented - alredy suitable for passing binary data around.

__add__, __sub__.  Easy to add others.
