Yuan Liu f6fe9fea99 migration/multifd: implement qpl compression and decompression 
QPL compression and decompression will use IAA hardware path if the IAA
hardware is available. Otherwise the QPL library software path is used.

The hardware path will automatically fall back to QPL software path if
the IAA queues are busy. In some scenarios, this may happen frequently,
such as configuring 4 channels but only one IAA device is available. In
the case of insufficient IAA hardware resources, retry and fallback can
help optimize performance:

 1. Retry + SW fallback:
    total time: 14649 ms
    downtime: 25 ms
    throughput: 17666.57 mbps
    pages-per-second: 1509647

 2. No fallback, always wait for work queues to become available
    total time: 18381 ms
    downtime: 25 ms
    throughput: 13698.65 mbps
    pages-per-second: 859607

If both the hardware and software paths fail, the uncompressed page is
sent directly.
