Switch hardened derivation marker to h in descriptors

Browse Source 
This makes it easier to handle descriptor strings manually. E.g. an RPC call that takes an array of descriptors can now use '["desc": ".../0h/..."]'.

Both markers can still be parsed. The default for new descriptors is changed to h. In normalized form h is also used. For private keys the chosen marker is preserved in a round trip.

The hdkeypath field in getaddressinfo is also impacted by this change.
