Init commit for opal vbdev. Opal vbdev is built based on
bdev part module. We split nvme namespace to spdk_bdev_part
with user specified offset and length. And then use this
configuration also to set up locking range for Opal.
Use linked list g_opal_vbdev to track all configuration for
each vbdev. And use g_opal_base to track the part_base for
all vbdevs.
This patch only shows the process for creating/deleting a vbdev
for an opal-enabled nvme ctrlr.
