e337f1ef5e py: Towards default keyword arguments. 
These are default arguments after a bare *.

523b575039 py: Add LOAD_NULL bytecode and use it to simplify function calls. 
Adding this bytecode allows to remove 4 others related to
function/method calls with * and ** support.  Will also help with
bytecodes that make functions/closures with default positional and
keyword args.

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.

bee17b00e3 py: Put n_state for bytecode in the bytecode prelude. 
Rationale: setting up the stack (state for locals and exceptions) is
really part of the "code", it's the prelude of the function.  For
example, native code adjusts the stack pointer on entry to the function.
Native code doesn't need to know n_state for any other reason.  So
putting the state size in the bytecode prelude is sensible.

It reduced ROM usage on STM by about 30 bytes :)  And makes it easier to
pass information about the bytecode between functions.

a8d31b28bc emitbc: Correct buffer sizes for varlen int encoding. 
Assuming we have truncating (floor) division, way to do ceiling division
by N is to use formula (x + (N-1)) / N. Specifically, 63 bits, if stored
7 bits per byte, require exactly 9 bytes. 64 bits overflow that and require
10 bytes.

ac2e28c654 Support passing positional args as keywords to bytecode functions. 
For this, record argument names along with each bytecode function. The code
still includes extensive debug logging support so far.

90750029df Implement default function arguments (for Python functions). 
TODO: Decide if we really need separate bytecode for creating functions
with default arguments - we would need same for closures, then there're
keywords arguments too. Having all combinations is a small exponential
explosion, likely we need just 2 cases - simplest (no defaults, no kw),
and full - defaults & kw.

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.

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).
