968bf34c4c py: Remove unnecessary LOAD_CONST_ID bytecode. 
It's the same as LOAD_CONST_STR.

db12891918 py: Eliminate 'op' variable in VM dispatch loop. 
Remembering the last op is rarely needed, and when it is, can simply use
*save_ip.

9d181f62dc py: Save some ROM by shortening compiler error messages. 
Messages are still explanatory, while taking a little less ROM.

2c0842b3c5 py: Change the way function arguments are compiled. 
New way uses slightly less ROM and RAM, should be slightly faster, and,
most importantly, allows to catch the error "non-keyword arg following
keyword arg".

Addresses issue #466.

2827d62e8b py: Implement keyword-only args. 
Implements 'def f(*, a)' and 'def f(*a, b)', but not default
keyword-only args, eg 'def f(*, a=1)'.

Partially addresses issue #524.

32bef315be py, gc: Only zero out the extra bytes at the end of the heap chunk. 
This is a small optimisation to zero out only the additional bytes that
the caller did not ask for.

27f5bdd6d4 py: "read" & "write" are so common that make them core. 
Few other strings move to core, but make depend on "io" module.

daab651c5c py, gc: Zero out newly allocated blocks in the GC. 
Also add some more debugging output to gc_dump_alloc_table().

Now that newly allocated heap is always zero'd, maybe we just make this
a policy for the uPy API to keep it simple (ie any new implementation of
memory allocation must zero all allocations).  This follows the D
language philosophy.

Before this patch, a previously used memory block which had pointers in
it may still retain those pointers if the new user of that block does
not actually use the entire block.  Eg, if I want 5 blocks worth of
heap, I actually get 8 (round up to nearest 4).  Then I never use the
last 3, so they keep their old values, which may be pointers pointing to
the heap, hence preventing GC.

In rare (or maybe not that rare) cases, this leads to long, unintentional
"linked lists" within the GC'd heap, filling it up completely.  It's
pretty rare, because you have to reuse exactly that memory which is part
of this "linked list", and reuse it in just the right way.

This should fix issue #522, and might have something to do with
issue #510.

3558f62fb5 py: Making closures now passes pointer to stack, not a tuple for vars. 
Closed over variables are now passed on the stack, instead of creating a
tuple and passing that.  This way memory for the closed over variables
can be allocated within the closure object itself.  See issue #510 for
background.
