This function returns the sign (-1, 0 or 1) of the integer object.

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.

When creating constant mpz's, the length of the mpz must be exactly how
many digits are used (not allocated) otherwise these numbers are not
compatible with dynamically allocated numbers.
Addresses issue #1448.
py: Implement divmod for mpz bignum.2015-06-13T22:38:28+00:00Damien Georgedamien.p.george@gmail.com2015-06-13T21:40:50+00:00urn:sha1:e9ce00d874ef6c93a56e726bb1503341f0448bf9py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.2015-05-12T21:46:02+00:00Damien Georgedamien.p.george@gmail.com2015-05-11T12:25:19+00:00urn:sha1:c2a4e4effc81d8ab21bb014e34355643e5ca0da2
Hashing is now done using mp_unary_op function with MP_UNARY_OP_HASH as
the operator argument. Hashing for int, str and bytes still go via
fast-path in mp_unary_op since they are the most common objects which
need to be hashed.
This lead to quite a bit of code cleanup, and should be more efficient
if anything. It saves 176 bytes code space on Thumb2, and 360 bytes on
x86.
The only loss is that the error message "unhashable type" is now the
more generic "unsupported type for __hash__".

This gets int.to_bytes working for bignum, and also struct.pack with 'q'
and 'Q' args on 32-bit machines.
Addresses issue #1155.
