for heights >= 2

* libs: Remove usage of custom Fmt, in favor of fmt.Sprintf

Closes #2193

* Fix bug that was masked by custom Fmt!

Our Tempfile was just a wrapper on ioutil that panicked instead of error.

Our Tempdir was a less safe variant of ioutil's Tempdir.

This reverts commit 58d0c8de89.

This reverts commit d02c5d1e30.

Also, fix consensus liveness issue.

This reverts commit 96a3502

This is a maintenance change to move the private validator package out
of the types and to a top-level location. There is no good reason to
keep it under the types and it will more clearly coommunicate where
additions related to the privval belong. It leaves the interface and the
mock in types for now as it would introduce circular dependency between
privval and types, this should be resolved eventually.

* mv priv_validator to privval pkg
* use consistent `privval` as import
