5aa311d330 py: Add attrtuple object, for space-efficient tuples with attr access.
If you need the functionality of a namedtuple but will only make 1 or a
few instances, then use an attrtuple instead.

7f9d1d6ab9 py: Overhaul and simplify printf/pfenv mechanism.
Previous to this patch the printing mechanism was a bit of a tangled
mess.  This patch attempts to consolidate printing into one interface.

All (non-debug) printing now uses the mp_print* family of functions,
mainly mp_printf.  All these functions take an mp_print_t structure as
their first argument, and this structure defines the printing backend
through the "print_strn" function of said structure.

Printing from the uPy core can reach the platform-defined print code via
two paths: either through mp_sys_stdout_obj (defined pert port) in
conjunction with mp_stream_write; or through the mp_plat_print structure
which uses the MP_PLAT_PRINT_STRN macro to define how string are printed
on the platform.  The former is only used when MICROPY_PY_IO is defined.

With this new scheme printing is generally more efficient (less layers
to go through, less arguments to pass), and, given an mp_print_t*
structure, one can call mp_print_str for efficiency instead of
mp_printf("%s", ...).  Code size is also reduced by around 200 bytes on
Thumb2 archs.

42e0c59308 py: Add MICROPY_COMP_{DOUBLE,TRIPLE}_TUPLE_ASSIGN config options.
These allow to fine-tune the compiler to select whether it optimises
tuple assignments of the form a, b = c, d and a, b, c = d, e, f.
Sensible defaults are provided.

0bfc7638ba py: Protect mp_parse and mp_compile with nlr push/pop block.
To enable parsing constants more efficiently, mp_parse should be allowed
to raise an exception, and mp_compile can already raise a MemoryError.
So these functions need to be protected by an nlr push/pop block.

This patch adds that feature in all places.  This allows to simplify how
mp_parse and mp_compile are called: they now raise an exception if they
have an error and so explicit checking is not needed anymore.

640e0b221e py: Implement very simple frozen modules support.
Only modules (not packages) supported now. Source modules can be converted
to frozen module structures using tools/make-frozen.py script.

5ebabcda41 minimal: Convert "bare-arm" port to "minimal" port.
This enable libc functions, GC, and line-editing function. Also, UART
emulation for POSIX systems is added. Emulation build is set as default.

d511a20a6b minimal: New port, intended to represent minimal working code.
Unlike bare-arm, which is mostly intended to show raw interpreter size,
without library and support code dependencies. This port is intended to
be a better base to start new ports, and also will include emulation
build to allow debug some aspects of embedded targets on POSIX systems.

This initial commit is verbatim copy of bare-arm code.
