For ACWU we always set value 1 because bdev holds
information specific for namespace only. This value
actually does not matter because we also set NACWU
which makes ACWU irrelevant. We set ACWU because
NVMe specs requires ACWU != 0 if fused commands
are supported.

A new API was added `spdk_bdev_io_get_aux_buf` allowing the caller to request
an auxiliary buffer for its own private use. The API is used in the same manner that
`spdk_bdev_io_get_buf` is used and the length of the buffer is always the same as the
bdev_io primary buffer. 'spdk_bdev_io_put_aux_buf' is called to free the
auxiliary buffer.
The initial use case is crypto, in the next patch in series it is used. No UT were
added as the logic isn't that complicated and it is fully tested with each run
of crypto.
Fixed a comment typo also (not mine for once).

Replaying md through _spdk_bs_load_replay_md_cpl() starts with
md page 0 in search of first valid md page starting a chain
for particular blob.
When it is found, next pages read are from the current pages
`next` page - next in chain.
After whole chain is read, it goes back to first page in chain
and starts search for next valid chain from there.
This patch adds separation between reading particular chain,
and moving to the next one.
Moving on to the next one happens in _spdk_bs_load_replay_md_chain_cpl().
Further in the series, extent pages will be added in the metadata.
Those are not within any particular blobs chain of metadata,
but spread out over the md region.
It is not enough to read all md and read extent pages.
In case of power failure, only extent pages known to be valid
are the ones which are pointed to by some valid md chain.
In futher patches, a step will be added after reading particular
valid md chain to go read extent pages pointed by it.

This commit provides the capability to install a
custom admin command handler for NVMF.
It can be used to implement or replace NVMe admin commands that
are currently not handled by the NVMF subsystem.
The handler implementation is pretty generic and the handler function
has to figure out what to do with the command based on the bdevs
that are configured for the subsystem.
In cases where admin commands need to be forwarded to an NVMe bdev,
the commit provides functions that allow access to the underlying bdev.
There is an example handler in lib/nvmf/custom_cmd_hdlr.c.

In current version, immidietly following parsing all
metadata pages an action is taken inform of loading the back_bs_dev.
Patches later in the series will add more metadata in form of
extent pages, which have to be read separetly from usual
blob metadata pages.
This patch add separation between the two steps,
so later a device read can be put between.
Additionally, _spdk_blob_load_final() when no snapshot was present
passed bserrno which was always 0. This patch just sets 0 directly
there as no errors occured at that point.

This was calling a callback for another function which
attempted to release the request. The code only worked because
in the r2t case the cb_arg was set to NULL, and that makes
the request free function do nothing.
