Currently we have both multi-thread compression and multifd to optimize
live migration in Qemu. Mulit-thread compression deals with the situation
where network bandwith is limited but cpu resource adequate. Multifd instead
aims to take full advantage of network bandwith. Moreover it supports both
Zlib compression has level from 1 to 9. However Zstd compression has level
from 1 to 22 (level >= 20 not recommanded). Let's do sanity check here
to make sure a vaild compress_level is given by user.

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.

Not quite. Device "SUNW,fdtwo" has user_creatable = false (it's a
sysbus device), and
We need the CCW address on the libvirt side to correctly identify
the disk, so add this information to the GuestDiskAddress on s390x.
