d66ae18640 py: Simplify stack get/set to become stack adjust in emitters.
Can do this now that the stack size calculation is improved.

6f355fd3b9 py: Make labels unsigned ints (converted from int).
Labels should never be negative, and this modified type signature
reflects that.

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.

922ddd6415 py, compile: Combine have_star_arg, have_dbl_star_arg into star_flags.
Small reduction in ROM, heap and stack usage.

882b363564 py: Move to Python 3.4.0 compatibility.
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.

In preparation for implementing default keyword arguments.

d17926db71 Rename rt_* to mp_*.
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.

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.

41d02b654e py: Improve freeing of emitters in mp_compile.
There can be multiple emitters allocated during compile (eg byte code
and native).

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.

d99b05282d 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).
