7f0419c0e5 objtype: Support calling normal methods inherited from native base class. 
Biggest part of this support is refactoring mp_obj_class_lookup() to return
standard "bound member" pair (mp_obj_t[2]). Actual support of inherited
native methods is 3 lines then. Some inherited features may be not supported
yet (e.g. native class methods, native properties, etc., etc.). There may
be opportunities for further optimization too.

186e463a9e py: Fix bug in map lookup of interned string vs non-interned. 
Had choice of either interning or forcing full equality comparison, and
chose latter.  See comments in mp_map_lookup.

0c8fcb9c49 py: Remove silly comment about interning keywords. 
Of course, keywords are turned into lexer tokens in the lexer, so will
never need to be interned (unless you do something like x="def").

As it is now, the following on pyboard makes no new qstrs:

    import pyb
    pyb.info()

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".

keyword-only args, eg 'def f(*, a=1)'.

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.
