the Query Processing Library (QPL) is an open-source library that
supports data compression and decompression features.

add --enable-qpl and --disable-qpl options to enable and disable
the QPL compression accelerator. The QPL compression accelerator
can accelerate the Zlib compression algorithm during the live migration.
