b1d67d86db63340dd64061def7eba6d6172cf0fa tests/migration-test: Merge shmem_opts into memory_backend
The two parameters are more or less duplicated in migrate_args(). They all
describe the memory type. When one is used, the other is not.
mem_type currently uses numa parameter to specify the memory backend, while
memory_backend (the two users of such uses "-machine memory-backend=ID").
This patch merges the use of the two variables so that we always generate a
memory object string and put it into "memory_backend" variable. Now we can
drop shmem_opts parameter in the function.
Meanwhile we always use a memory-backend-* no matter which mem type is
used. This brings mem_type to be aligned with memory_backend usage, then
we stick with this as this is flexible enough.
This paves way that we merge mem_type and memory_backend in MigrateStart.
