py/binary.c: Fix bug when packing big-endian 'Q' values.
Without bugfix:
struct.pack('>Q', 16)
b'\x00\x00\x00\x10\x00\x00\x00\x00'
With bugfix:
struct.pack('>Q', 16)
b'\x00\x00\x00\x00\x00\x00\x00\x10'

py/binary: Handle storing big-ints to all arrays types.
Prior to this patch only 'q' and 'Q' type arrays could store big-int
values. With this patch any big int that is stored to an array is handled
by the big-int implementation, regardless of the typecode of the array.
This allows arrays to work with all type sizes on all architectures.

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.

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.

py: Start implementing "struct" module.
Only calcsize() and unpack() functions provided so far, for little-endian
byte order. Format strings don't support repition spec (like "2b3i").
Unfortunately, dealing with all the various binary type sizes and alignments
will lead to quite a bloated "binary" helper functions - if optimizing for
speed. Need to think if using dynamic parametrized algos makes more sense.
