Remove unused private members.

That's a lot of unused code. Most of this is pure cruft; a small
amount is debugging code which somebody might want to keep around,
but we should not be using trunk as a repository of our personal
snippets of undocumented, unused, unintegrated debugging code. So
let's make the easy decision to err in the removing direction.
If it isn't built to last, it shouldn't be checked into master.
