[libvirt] [PATCH v2 47/73] qemu: Drop qemuMigrationCompression structure

By merging qemuMigrationAnyCompressionParse into qemuMigrationParamsSetCompression we can drop the useless intermediate qemuMigrationCompression structure and parse compression related typed parameters and flags directly into qemuMigrationParams.
