* Rename '_py_stats' variable to '_Py_stats'. * Exclude Include/cpython/pystats.h from the Py_LIMITED_API. * No longer export _py_stats_struct variable. * Move pystats.h include from object.h to Python.h. * Add comments to Include/pystats.h and Include/cpython/pystats.h. * Doc/using/configure.rst lists sys functions addedd by Py_STATS.
