    Replace all uses of Perl <> with <<>>.
    
    I've only just found out that it has the effect of treating the argv
    words not as plain filenames, but as arguments to Perl default 'open',
    i.e. if they end in | then the text before that is treated as a
    command. That's not what was intended in any of these contexts!
    
    Fortunately, in this project it only comes up in non-critical
    'contrib' scripts.

    cryptsuite: switch #! line to Python 3.
    
    Since I apparently can't reliably keep this script working on both
    flavours of Python, I think these days I'd rather it broke on 2 than
    on 3 due to my inattention. So let's default to 3.

    Run cryptsuite in the autotools makefile's 'make check'.
    
    Now we've _got_ a test suite, this seems like an obviously useful
    place to put an invocation of it.

    Bitsliced AES: optimise the constant out of the S-box.
    
    In the bitsliced implementation, the addition of 0x63 as the last
    operation inside the S-box actually costs cycles during encryption -
    four bitslice inversions - which can be easily eliminated by detaching
    the constant, moving it forward past the ShiftRows and MixColumns
    (with both of which it commutes) until it's adjacent to the next round
    key addition, and then folding it into the round key during key setup.
    
    I had this idea while I was originally writing this implementation,
    but deferred actually doing it because it made all the intermediate
    results harder to check against the standard test vectors. Now the
    code is working and stable, this is the moment to come back and do it.
