Add the 'oncs' nvme device parameter to allow optional features to be
enabled/disabled explicitly. Since most of these are optional commands,
make the CSE log pages dynamic to account for the value of ONCS.

Add support for marking blocks invalid with the Write Uncorrectable
command. Block status is tracked in a (non-persistent) bitmap that is
checked on all reads and written to on all writes. This is potentially
expensive, so keep Write Uncorrectable disabled by default.

Many _unsupported_imgopts lines for refcount_bits values use something
