Remove deprecated re-exports

Recently we added a bunch of deprecated re-exports while moving things
out of the util module. Turns out while the code reads like it works,
`deprecated` actually only works for functions, not types or modules
etc.

Remove the non-functional deprecated lines and elect to _not_ re-export
things we moved. Release 0.30 is going to break a lot of code but there
is no real nice way to resolve that. We will need good release notes and
a public apology probably :)

Fix import statements that still rely on `util::bip32` - these should
have been fixed when we moved the `bip32` module.
