Memory domain is used to describe memory which belongs to
another address space (e.g. GPU memory or host memory)
Memory domain can be configured with callbacks to translate
data to another memory domain and to fetch data to
local buffers.
Memory domains will be used in extended

Actually we should not re-enable the ADMIN queue during
the memory region callback, similar with the IO queues,
we should just do the remap, but to avoid changing other
values such as doorbells.
This is a preparation patch just to rename it, and will fix
the issue in coming patchs.

Currently, queue creation is delegated to nvmf_vfio_user_accept() for both I/O
and admin queues, by adding it to a ->new_qps list. But there's no good reason
for this indirection to exist, and it would make interrupt support for the
accept poller harder to implement. Instead, directly call
spdk_nvmf_tgt_new_qpair().

Multiple IO Submission Queue can share one Completion Queue, and
we use field 'cqid' to save it in Submission Queue, so when posting
completion response, we need to get the Submission Queue's CQID first,
then post the completion queue based on CQID.
Also rename vfio-user internal variables with 'vu_' prefix in this
function.
