py/objint_longlong: Add stub for mp_obj_int_from_bytes_impl().

To be implemented later.

py/objint: Rename mp_obj_int_as_float to mp_obj_int_as_float_impl.
...
And also simplify it to remove the check for small int. This can be done
because this function is only ever called if the argument is not a small
int.

py/objint: Use size_t for arguments that measure bytes/sizes.

py: Use MP_SMALL_INT_POSITIVE_MASK to check if uint fits in a small int.
...
Using the original WORD_MSBIT_HIGH-logic resulted in errors when the
object model is not REPR_A or REPR_C.

py: Change mp_obj_int_is_positive to more general mp_obj_int_sign.
...
This function returns the sign (-1, 0 or 1) of the integer object.

py/objint_longlong: Instead of assert, throw OverflowError.

py: Rename MP_BOOL() to mp_obj_new_bool() for consistency in naming.

py: Convert hash API to use MP_UNARY_OP_HASH instead of ad-hoc function.
...
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__".

py: Support conversion of bignum to bytes.
...
This gets int.to_bytes working for bignum, and also struct.pack with 'q'
and 'Q' args on 32-bit machines.
Addresses issue #1155 .

12033df511
py: Partially fix float to int conversion.
...
This fixes conversion when float type has more mantissa bits than small int,
and float value has small exponent. This is for example the case of 32-bit
platform using doubles, and converting value of time.time(). Conversion of
floats with larg exponnet is still not handled correctly.

py: Rename mp_obj_int_get to mp_obj_int_get_truncated; fix struct.pack.
...
mp_obj_int_get_truncated is used as a "fast path" int accessor that
doesn't check for overflow and returns the int truncated to the machine
word size, ie mp_int_t.
Use mp_obj_int_get_truncated to fix struct.pack when packing maximum word
sized values.
Addresses issues #779 and #998 .

py: Correctly set sys.maxsize value for 64-bit.
...
Type representing signed size doesn't have to be int, so use special value
which defaults to SSIZE_MAX, but as it's not defined by C standard (but rather
by POSIX), allow ports to set it.

Implementing it as a static constant is a bit peculiar and require cooperation
from long int implementation.
