py/objint: In int.from_bytes, only create big-int if really needed.
...
This patch ensures that int.from_bytes only creates a big-int if necessary,
by checking the value for a small-int overflow as it's being parsed.

py/objint: Consolidate mp_obj_new_int_from_float to one implementation.

This reduces code duplication and allows to make mp_classify_fp_as_int
static, which reduces code size.

py/objint: Handle special case of -0 when classifying fp as int.
...
Otherwise -0.0 is classified as a bigint, which for builds without bigints
will lead unexpectedly to an overflow.

py/objint: Allow to print long-long ints without using the heap.
...
Some stack is allocated to format ints, and when the int implementation uses
long-long there should be additional stack allocated compared with the other
cases. This patch uses the existing "fmt_int_t" type to determine the
amount of stack to allocate.

py/objint: from_bytes(): Implement "byteorder" param and arbitrary precision.
...
If result guaranteedly fits in a small int, it is handled in objint.c.
Otherwise, it is delegated to mp_obj_int_from_bytes_impl(), which should
be implemented by individual objint_*.c, similar to
mp_obj_int_to_bytes_impl().

py/objint: Simplify mp_int_format_size and remove unreachable code.
...
One never needs to format integers with a base larger than 16 (but code
can be easily extended beyond this value if needed in the future).

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: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.
...
The first argument to the type.make_new method is naturally a uPy type,
and all uses of this argument cast it directly to a pointer to a type
structure. So it makes sense to just have it a pointer to a type from
the very beginning (and a const pointer at that). This patch makes
such a change, and removes all unnecessary casting to/from mp_obj_t.

py: Change type of .make_new and .call args: mp_uint_t becomes size_t.
...
This patch changes the type signature of .make_new and .call object method
slots to use size_t for n_args and n_kw (was mp_uint_t. Makes code more
efficient when mp_uint_t is larger than a machine word. Doesn't affect
ports when size_t and mp_uint_t have the same size.

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.
