Recent CMB changes disable using the CMB copy and submission queue
at the same time, so disable use_cmb_sqs by default.
Also spdk_nvme_ctrlr_map_cmb() changed the "size" parameter used as
size of buffer that was mapped, so change it here too.

Instead of creating an allocator where the driver manages the space,
now, since using the CMB for queues and data has already been
disallowed, just create functions to map and unmap the entire CMB.
The user can manage the space.

Add a new example application that copies data between two NVMe
namespaces, on two different NVMe controllers via the CMB that belongs
to one of said controllers. This avoids using CPU system memory as a
DMA buffer and reduces the number of external DMAs from two to one.
Use:
./cmb_test -h
for usage.
