5d9b816449 py: Fix bug in mpn_shl (multi-prec int shift left). 
Before this patch, eg, 1 << 75 (or any large multiple of 15) was setting
the MSB in the digits, which is outside the valid range of DIG_MASK.

c9aa58e638 py: Improve handling of long-int overflow. 
This removes mpz_as_int, since that was a terrible function (it
implemented saturating conversion).

Use mpz_as_int_checked and mpz_as_uint_checked.  These now work
correctly (they previously had wrong overflow checking, eg
print(chr(10000000000000)) on 32-bit machine would incorrectly convert
this large number to a small int).

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/.

57207b8818 objint_mpz: Quick&dirty implementation of bitwise operations. 
Made solely to unbreak int-long.py test which in turn uncovered thinko
with implementation of inplace ops. On mpz level, bitwise ops implemented
only for same-sign numbers, and are not efficient (unconditional calling of
mpn_cmp() is apparently superfluous).

06201ff3d6 py: Implement bit-shift and not operations for mpz. 
Implement not, shl and shr in mpz library.  Add function to create mpzs
on the stack, used for memory efficiency when rhs is a small int.
Factor out code to parse base-prefix of number into a dedicated function.

438c88dd2f Add arbitrary precision integer support. 
Some functionality is still missing (eg and, or, bit shift), and some
things are buggy (eg subtract).
