Mostly trivial enum fixes

This is a patch I extracted from Pedro's C++ branch.  It contains the
most trivial enum fixes, where an integer type/value was used instead
of the appropriate enum type/value.  It fixes many C++ errors, since
in C++ you can't mix integers and enums implicitely.

Regardless of the C++ conversion, I think this is a good cleanup to make
use of the appropriate enum types.

Regression-tested on native x86_64.
