During spdk_bdev_init, examine_config is called.
This call can claim bdev synchronously, based on
configuration. On spdk_bdev_start if none module
claimed bdev, examine_disk is called and can
perform I/O before claiming bdev.

For application like vhost/iSCSI target/NVMe-oF target/etc,
a new section as below can be added for the QoS rate limiting.
[QoS]
Limit_IOPS Malloc0 100000
Limit_IOPS Nvme0n1 500000
Also added a sample change at test/lib/bdev/bdev.conf.in

SPKD base bdev might be part of multiple vbdevs. The same is true in
reverse direction. So consider folowing scenario:
bdev3 bdev4 bdev5
| | |
+-+--+ + +--+--+
/ \ | / \
bdev0 bdev1 bdev2
In current implementation bdev0/1/2 will apear as base base for
bdev3/4/5 which is obviously wrong.
This patch try to address this issue.

This better matches the style in the rest of SPDK.
No functional change - this is a pure find/replace of
spdk_bdev_module_if to spdk_bdev_module. Instances of this struct will
be renamed in another patch.

Currently SPDK_BDEV_MODULE_REGISTER() take many parameters. Extending it
(eg for incoming JSON configuration dump/load) is quite challenging and
error prone. As we are already here in next patches, rework this macro
to take one parameter - the pointer to struct spdk_bdev_module_if.
This patch also remove following macros:
SPDK_GET_BDEV_MODULE - this is not really needed, to find module outside
module translation unit use spdk_bdev_module_list_find()
SPDK_BDEV_MODULE_ASYNC_INIT and SPDK_BDEV_MODULE_ASYNC_FINI - replaced
by bool fields in spdk_bdev_module_if struct.
