Add a helper function bdev_reset_device_stat() to reset I/O statistics.
This funciton is used for the bdev_reset_iostat RPC.
We do not have any plan to use bdev_reset_device_stat() outside
lib/bdev. Hence, we do not add this as a public API.
Then, add a new RPC bdev_reset_iostat to reset I/O statistics of a
single bdev or all bdevs.
Resetting I/O statistics affects all consumers. Add a note to CHANGELOG
and doc/jsonrpc.md.

SPDK threads generally run on dedicated cores and locks should be rarely

not free up CPU cycles for other pthreads or processes. Even when

partual bdevs or even return an empty list if the hot remove bdev is

optional arguments:

-b NAME, --name NAME Name of the Blockdev. Example: Nvme0n1
-c, --per-channel Display per channel IO stats for specified device
This could give more intuitive information on each channel's processing
of the IOs with the associated thread on the same Bdev.
Please also be aware that the IO statistics are collected from SPDK
thread's related channel's information. So that it is more relating
to the SPDK thread. And in the dynamic scheduling case, different
SPDK thread could be running on the same Core.
In this case, any seperate channel's IO statistics are returned to
the RPC call and if needed, further parse of the data is needed to
get the per Core information although usually there is one thread
per Core.
On the other hand, user could run the framework_get_reactors RPC
method to get the relationship of the thread and CPU Cores so as
to get the precise information of IO runnings on each thread and
each Core for the same Bdev.

The io_drain_timeout controls how long a bdev reset must wait for IO

If there is no outstanding IO at the end of that period, the reset

The generic bdev layer has a public API spdk_bdev_get_qd() but its
value is the most recently measured value and it requires qd sampling
to be enabled. We will have bdev modules to want to wait until
all bdev_ios are aborted by a reset. Unfortunately, spdk_bdev_get_qd()
is not suitable for the custom bdev module. Furthermore,
spdk_bdev_channel::io_outstanding is not accessible from bdev modules.
Hence, add a new public API spdk_bdev_get_current_qd().
This function should be used only from the bdev module and it should
be ensured that the bdev is not unregistered during execution.

If the bdev does not natively support compare we use
the fall-back which performs a read instead of a compare
operation. We then compare the results of the read with
the buffer provided by the user. In case the bdev has
metadata, there are two options:
1) md is interleaved -> the md will be part of the data
buffer allocated for the read and compared accordingly
2) md is separate -> currently we do not compare
the metadata but just ignore it.
This patch fixes 2) by comparing the md buffer after
the read is done.

When a bdev is registered, it is examined by the bdev modules before the
bdev register even is notified.
Examination may be asychronous, e.g. when the bdev module has to perform
I/O on the new bdev.
This causes a race condition where the bdev might be destroyed while
examination is not finished. Then, once all modules have signaled that
examination is done, `bdev_register_finished` makes an invalid access to
the freed bdev pointer.
To fix this, defer the unregistration until the examine is completed by
opening a descriptor on the bdev.

It is a nicer API to allow users to use an
md-related API such as spdk_bdev_read_blocks_with_md
passing md_buf as NULL to mean "don't read metadata".
This avoids the need for an if-statement in the users
code to check if the md buffer is NULL before deciding
which API needs to be called.
This basically requires two changes:
1) only check if the metadata is separate for the bdev
if the md_buf != NULL
2) do not fail if the buffer is specified but the
md buffer is not (we only need to fail the case where
the md buffer is specified but the data buffer is not)
Note that spdk_bdev_readv/writev_blocks_ext was already
allowing the metadata buffer to be NULL, but change
those functions too to match the others on how we check
if the data buffer isn't allocated.

In many cases, addressing bdevs by their UUIDs is often easier than
using their names, which can be somewhat arbitrary. For instance, the
NVMe bdev builds a name by addng the n{NSID} suffix to the controller's
name, while the UUID is filled with NGUID (if available).
The UUID alias is stored in the form defined by RFC 4122, meaning five
groups of lower-case hexadecimal characters. It's important to note
that bdev layer uses case-sensitive name comparison, so the user needs
to use the same textual UUID representation.

In the bdev-zone API, there are a few functions that takes a zone_id:
spdk_bdev_get_zone_info(), spdk_bdev_zone_management(), and the
spdk_bdev_zone_append() functions.
The way a zoned application is usually written is that it starts off
by getting the zone report for all zones (zone_id will be sent in as 0),
and then the application will keep the whole zone report in memory.
Therefore, an application usually have access to the zone_id/zslba for
all zones. However, there are cases, e.g. when getting an error on write,
where the completion callback will only have the lba of the write that
failed.
Add a helper function that can be used to get the zone_id/slba for a
given lba. Having this helper in bdev-zone will avoid SPDK applications
needing to provide their own implementation for this.

Callback for bdev modules is called 'module_fini',
meanwhile after its execution bdev modules were to call
'spdk_bdev_module_finish_done()'.
This function carries incorrect name, so it was deprecated
and replaced with 'spdk_bdev_module_fini_done()'.
