 * modffi uses character codes to encode a value type, based on "struct"
 * module type codes, with some extensions and overridings.
 *
 * Extra/overridden typecodes:
 *      v - void, can be used only as return type
 *      P - const void*, pointer to read-only memory
 *      p - void*, meaning pointer to a writable memory (note that this
 *          clashes with struct's "p" as "Pascal string").
 *      s - as argument, the same as "p", as return value, causes string
 *          to be allocated and returned, instead of pointer value.
 *      O - mp_obj_t, passed as is (mostly useful as a callback param)
 *
 * TODO:
 *      C - callback function
 *
 * Note: all constraint specified by typecode can be not enforced at this time,
 * but may be later.

@Import micropython version 1.5.2 into othersrc.

Micropython is a python3 implementation that has been optimised for
micro-controllers and small embedded systems.  It also has a "unix"
port. It has an MIT license.

This is version 1.5.2 of micropython.

	MicroPython implements the entire Python 3.4 syntax (including
	exceptions, "with", "yield from", etc.).  The following core
	datatypes are provided:  str (including basic Unicode
	support), bytes, bytearray, tuple, list, dict, set, frozenset,
	array.array, collections.namedtuple, classes and instances. 
	Builtin modules include sys, time, and struct.  Note that only
	subset of Python 3.4 functionality implemented for the data
	types and modules.

This is the standard micropython source (version v1.5.2), which has been
adapted to use reachover infrastructure. At the present time, libffi
(from pkgsrc) is used. Alternative locations for libffi can be set
using the PKGSRC_PREFIX definition to make.

In the whole scheme of things, micropython is quite small:

	% size bin/micropython
	   text    data     bss     dec     hex filename
	 393495    1624    2208  397327   6100f bin/micropython
	%

and runs much as expected:

	% bin/micropython
	MicroPython v1.5.2 on 2016-01-13; linux version
	Use Ctrl-D to exit, Ctrl-E for paste mode
	>>> print("hello world")
	hello world
	>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
	[4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46]

	Type "help", "copyright", "credits" or "license" for more information.
	>>> print("hello world")
	hello world
	>>> list(5 * x + y for x in range(10) for y in [4, 2, 1])
	[4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46]
	>>> ^D

This (reachover) version runs all the tests which the gmake version does.
