1463c1fa82 py: Add MICROPY_ENABLE_DOC_STRING, disabled by default.
Also add a few STATIC's to some compile functions that should have them.

Addresses issue #521.

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.

This is a one-liner fix.  It gets the class-super.py test passing, but
is probably not a complete fix.

3 emitter functions are needed only for emitcpy, and so we can #if them
out when compiling with emitcpy support.

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.

a3f94e0030 py: Add arg checking helper functions.
These are to assist in writing native C functions that take positional
and keyword arguments.  mp_arg_check_num is for just checking the
number of arguments is correct.  mp_arg_parse_all is for parsing
positional and keyword arguments with default values.
