py: Disable dump_args function call entirely when not debugging.
Yes, I know, a good compiler will optimise this away, but I feel this is
neater.

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.

objexcept: No more magic messages in exceptions, only exception arguments.
One of the reason for separate "message" (besides still unfulfilled desire to
optimize memory usage) was apparent special handling of exception with
messages by CPython. Well, the message is still just an exception argument,
it just printed specially. Implement that with PRINT_EXC printing format.

Pretty much everyone needs to include map.h, since it's such an integral
part of the Micro Python object implementation. Thus, the definitions
are now in obj.h instead. map.h is removed.

vm: Save current active exception on opening new try block.
Required to reraise correct exceptions in except block, regardless if more
try blocks with active exceptions happen in the same except block.
P.S. This "automagic reraise" appears to be quite wasteful feature of Python
- we need to save pending exception just in case it *might* be reraised.
Instead, programmer could explcitly capture exception to a variable using
"except ... as var", and reraise that. So, consider disabling argless raise
support as an optimization.

This reduntant triple is one of the ugliest parts of Python, which they

but until we do, let's follow CPython layout.
