Introduce disable_validate_hash

disable_validate_hash does as its name suggests.

After Master-hash has been fully verified then ALL subsequent hashes
are considered to be valid.
* disable_validate_hash=1

The one exception being Master-hash, which is still validated.
* unset disable_validate_hash
