* requires only the set bits in mcreds be set in creds;
* MATCH_FLAGS_EXACT requires all bits to match.

* Flag SUPPORTED_KTYPES means check all matching entries that have

/* I am grateful to Frank Yellin for the following construction
(and that for decryption) which, given the column (c) of the
output state variable, gives the input state variables which
are needed for each row (r) of the state.
For the fixed block size options, compilers should reduce these
two expressions to fixed variable references. But for variable
block size code conditional clauses will sometimes be returned.
y = output word, x = input word, r = row, c = column for r = 0,
1, 2 and 3 = column accessed for row r.
