The legacy serialization was vulnerable to maleation and is fixed by
adopting the same serialization procedure as was already in use for
MuHash.
This also includes necessary test fixes where the hash_serialized2 was
hardcoded as well as correction of the regtest chainparams.

621db2f004 test: assumeutxo file with unknown block hash (Fabian Jahr)
Pull request description:
Takes care of one of the open Todos in the assumeutxo functional test. Since an unknown block could be any hash, I simply chose one placeholder, it could also be a random string though.

Current getchainstates RPC returns "normal" and "snapshot" fields which are not
ideal because it requires new "normal" and "snapshot" terms to be defined, and
the definitions are not really consistent with internal code. (In the RPC
interface, the "snapshot" chainstate becomes the "normal" chainstate after it
is validated, while in internal code there is no "normal chainstate" and the
"snapshot chainstate" is still called that temporarily after it is validated).
The current getchainstatees RPC is also awkward to use if you to want
information about the most-work chainstate because you have to look at the
"snapshot" field if it exists, and otherwise fall back to the "normal" field.
Fix these issues by having getchainstates just return a flat list of
chainstates ordered by work, and adding new chainstate "validated" field
alongside the existing "snapshot_blockhash" so it is explicit if a chainstate
was originally loaded from a snapshot, and whether the snapshot has been
validated.
