Subject: [PATCH] signature: Fix pointers to signature bytes with the highest
 bit set

If a pointer to signature bytes has the highest bit set (e.g. 0xf6dd2840 on
32bit), it is interpreted as negative Py_ssize_t value by Py_BuildValue.
PyLong_AsSize_t cannot convert this into size_t and returns -1, resulting
in an invalid pointer.

To avoid this, use PyLong_AsSsize_t and intptr_t instead.
