#3743: PY_FORMAT_SIZE_T is designed for the OS "printf" functions, not for

PyString_FromFormat which has an independent implementation, and uses "%zd".

This makes a difference on win64, where printf needs "%Id" to display
64bit values. For example, queue.__repr__ was incorrect.

- Issue #3743: In a few places, PY_FORMAT_SIZE_T was incorrectly used with
PyString_FromFormat or PyErr_Format to display size_t values. The macro
PY_FORMAT_SIZE_T is designed to select the correct format for the OS
``printf`` function, whereas PyString_FromFormat has an independent
implementation and uses "%zd" on all platforms for size_t values.
This makes a difference on win64, where ``printf`` needs "%Id" to display
64bit values.
