Damien George 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.

Damien George df8127a17e py: Remove unique_codes from emitglue.c. Replace with pointers.
Attempt to address issue #386.  unique_code_id's have been removed and
replaced with a pointer to the "raw code" information.  This pointer is
stored in the actual byte code (aligned, so the GC can trace it), so
that raw code (ie byte code, native code and inline assembler) is kept
only for as long as it is needed.  In memory it's now like a tree: the
outer module's byte code points directly to its children's raw code.  So
when the outer code gets freed, if there are no remaining functions that
need the raw code, then the children's code gets freed as well.

This is pretty much like CPython does it, except that CPython stores
indexes in the byte code rather than machine pointers.  These indices
index the per-function constant table in order to find the relevant
code.

Damien George 11d8cd54c9 py, compiler: Turn id_info_t.param into a set of flags.
So we can add more flags.

Damien George 78035b995f py, compiler: Clean up and compress scope/compile structures.
Convert int types to uint where sensible, and then to uint8_t or
uint16_t where possible to reduce RAM usage.

Paul Sokolovsky ab5d08280b Allow qstr's with non-ident chars, construct good identifier for them.
Also, add qstr's for string appearing in unix REPL loop, gross effect
being less allocations for each command run.

Damien George 55baff4c9b Revamp qstrs: they now include length and hash.
Can now have null bytes in strings.  Can define ROM qstrs per port using
qstrdefsport.h

Damien George cbd2f7482c py: Add module/function/class name to exceptions.
Exceptions know source file, line and block name.

Also tidy up some debug printing functions and provide a global
flag to enable/disable them.

Damien 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).
