ef61b5ecb5 Initial merge of micropython v1.9.2 into circuitpython 2.0.0 (in development) master. 
cpx build compiles and loads and works in repl; test suite not run yet
esp8266 not tested yet

55f33240f3 all: Use the name MicroPython consistently in comments 
There were several different spellings of MicroPython present in comments,
when there should be only one.

94c41bb06f py: Use mp_raise_TypeError/mp_raise_ValueError helpers where possible. 
Saves 168 bytes on bare-arm.

c2dd494bd9 py/parsenum: Simplify and generalise decoding of digit values. 
This function should be able to parse integers with any value for the
base, because it is called by int('xxx', base).

561844f3ba py: Add MICROPY_FLOAT_CONST macro for defining float constants. 
All float constants in the core should use this macro to prevent
unnecessary creation of double-precision floats, which makes code less
efficient.

7d0d7215d2 py: Use mp_raise_msg helper function where appropriate. 
Saves the following number of bytes of code space: 176 for bare-arm, 352
for minimal, 272 for unix x86-64, 140 for stmhal, 120 for esp8266.

2599672384 py/parsenum: Use pow function to apply exponent to decimal number. 
Pow is already a dependency when compiling with floats, so may as well
use it here to reduce code size and speed up the conversion for most
cases.

dddb98db8b py/parsenum: Use size_t to count bytes, and int for type of base arg. 
size_t is the proper type to count number of bytes in a string.  The base
argument does not need to be a full mp_uint_t, int is enough.

999cedb90f py: Wrap all obj-ptr conversions in MP_OBJ_TO_PTR/MP_OBJ_FROM_PTR. 
This allows the mp_obj_t type to be configured to something other than a
pointer-sized primitive type.

This patch also includes additional changes to allow the code to compile
when sizeof(mp_uint_t) != sizeof(void*), such as using size_t instead of
mp_uint_t, and various casts.

5f3c3ec5e6 py/parsenum: Provide detailed error for int parsing with escaped bytes. 
This patch adds more fine grained error message control for errors when
parsing integers (now has terse, normal and detailed).  When detailed is
enabled, the error now escapes bytes when printing them so they can be
more easily seen.

0ec8cf8e80 py/parsenum.c: Rename "raise" func to "raise_exc" to avoid name clash. 
"raise" is a common word that was found to exist in a vendor's stdlib.

7d414a1b52 py: Parse big-int/float/imag constants directly in parser. 
Previous to this patch, a big-int, float or imag constant was interned
(made into a qstr) and then parsed at runtime to create an object each
time it was needed.  This is wasteful in RAM and not efficient.  Now,
these constants are parsed straight away in the parser and turned into
objects.  This allows constants with large numbers of digits (so
addresses issue #1103) and takes us a step closer to #722.

1e9a92f84f py: Use shorter, static error msgs when ERROR_REPORTING_TERSE enabled. 
Going from MICROPY_ERROR_REPORTING_NORMAL to
MICROPY_ERROR_REPORTING_TERSE now saves 2020 bytes ROM for ARM Thumb2,
and 2200 bytes ROM for 32-bit x86.

This is about a 2.5% code size reduction for bare-arm.

3b6f7b95eb py: Separate MICROPY_PY_BUILTINS_COMPLEX from MICROPY_PY_BUILTINS_FLOAT. 
One thing is wanting to do 1 / 2 and get something else but 0, and quite
another - doing rocket science ;-).

0294661da5 parsenum: Signedness issues. 
char can be signedness, and using signedness types is dangerous - it can
lead to negative offsets when doing table lookups. We apparently should just
ban char usage.

fb510b3bf9 Rename bultins config variables to MICROPY_PY_BUILTINS_*. 
This renames:
MICROPY_PY_FROZENSET -> MICROPY_PY_BUILTINS_FROZENSET
MICROPY_PY_PROPERTY -> MICROPY_PY_BUILTINS_PROPERTY
MICROPY_PY_SLICE -> MICROPY_PY_BUILTINS_SLICE
MICROPY_ENABLE_FLOAT -> MICROPY_PY_BUILTINS_FLOAT

See issue #35 for discussion.

04b9147e15 Add license header to (almost) all files. 
Blanket wide to all .c and .h files.  Some files originating from ST are
difficult to deal with (license wise) so it was left out of those.

Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
