* WIP on removing tm pub/privkey * Fix part of crypto tests * Add PrivKeyLedgerSecp256K1 proto type * Use BasePrivKey for ledger priv key type * Refacto continued * First round * x/staking * Continue porting * x/* done * Make build pass * More conversion * Remove IntoTmPubKey * Fix test * Remove crypto.PubKey in some other places * Revert ledger changes * Fix comment * Remove useless function * Add To/FromTmPublicKey * Add migrate tests * Fix test * Fix another test * Rename tm conversion functions * Less code * Rename BasePrivKey to LedgerPrivKey * Add changelog * Rename functions Co-authored-by: Amaury Martiny <amaury.martiny@protonmail.com> Co-authored-by: Alessio Treglia <alessio@tendermint.com>
