    support lzop save compression for qemu · cc76cf31

    Per prior discussion -- this was, indeed, trivial.
    
    I'm a little disappointed to be breaking the ordering characteristics of
    the enum (as it had been ordered by increasing time requirements and
    decreasing output size), but breaking any save files with the old
    constants in the headers would of course be worse.

    Subject: [PATCH] support lzop save compression for qemu
    
    One of the larger disincentives towards use of compression for migrated-out save
    files is performance impact. This patch adds support for lzop; CPU time for
    compression is about 5x faster than gzip (the next most performant algorithm)
    and decompression is about 3x faster.
