Code refactor for the compression procedure which includes: 1. Move qemu_compress_data and qemu_put_compression_data from qemu-file.c to ram.c, for the reason that most part of the code logical has nothing to do with qemu-file. Besides, the decompression code is located at ram.c only. 2. Simplify the function input arguments for compression and decompression. Wrap the input into the param structure which already exists. This change also makes the function much more flexible for other compression methods. Signed-off-by: Zeyu Jin <jinzeyu@huawei.com> Signed-off-by: Ying Fang <fangying1@huawei.com>
