commit a49d154f4a8e493baf2296a15c7b5c56cd25e993

pybind: Fix C type errors in Cython-generated Python bindings
Several Ceph APIs use bool * types, which correspond to
libcpp.bool * types in Cython. The bint type has an incorrect
size 4 and cannot be used as a replacement.
This prevents a compilation failure with future compilers:
