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()'.

fini_start() is called for each bdev module before
iterating over all unclaimed bdevs to unregister them.
This allows bdev modules to behave differently during
each such unregister. Ex. unloading lvol store when
all lvol bdevs on it are unregistered.
Another use of this callback is to unclaim all bdevs
that can be at that point. Especially ones that will
not receive callback due to no bdev registered.
Ex. offline raid bdev, when some underlying bdevs are missing.
fini_start() being synchronous does not help in cases
where to release claim on the bdev, an asynchronous operation
is required. Ex. lvol store with no bdevs present, requires
async lvs unload to be called.
This patch adds async_fini_start flag for the bdev modules,
to be used when async fini_start is required. When done,
bdev module has to call spdk_bdev_module_finish_start_done().

We had not held mutex while removing bdev name or alias from bdev
name tree for most cases. Fix these in this patch.
spdk_bdev_unregister() already holds g_bdev_mgr.mutex when removing
name, and so we do not need to change it.
spdk_bdev_close() had not held g_bdev_mgr.mutex. What we want to lock
is only when removing name from name tree, that is, calling
bdev_name_del() in bdev_unregister_unsafe(). However, we need to
keep hierarchical lock ordering. Hence get and free g_bdev_mgr.mutex
outside of bdev->internal.mutex.

spdk_bdev_register() and spdk_bdev_add_alias() had not held mutex when
adding bdev name or alias to global bdev name tree. This bug caused unexpected
error when traversing global bdev name tree.
The next patch will fix the bug. This patch is a preparation for the fix.
spdk_bdev_get_by_name() had not held mutex while traversing bdev
name tree. The major callers to spdk_bdev_get_by_name() had held mutex
when calling it. However, this was not clear.
Factor out the internal of spdk_bdev_get_by_name() into a helper
function bdev_get_by_name() and then change spdk_bdev_get_by_name()
to lock and unlock when calling bdev_get_by_name().
Then replace spdk_bdev_get_by_name() call in spdk_bdev_alias_add() and
bdev_register() by bdev_get_by_name() call.
spdk_bdev_get_by_name() call in spdk_bdev_examine() is not changed.
This is called only from JSON RPC and not related with the bug. So
we want to fix only unlocked access to global bdev name tree.

For correct behaviour, pthread_mutex should not be locked after it has
been destroyed.
g_bdev_mgr.mutex is statically initialized. It is destroyed in
bdev_mgr_unregister_cb, but not re-initialized in spdk_bdev_initialize.
Repeated calls to initialize/unregister occur during unit tests.
Remove the destroy from bdev_mgr_unregister_cb, which seems
the simplest way of resolving the issue.
The sequence: spdk_put_io_channel(), spdk_bdev_close(),
spdk_bdev_unregister() occurs during unit tests.
spdk_bdev_unregister() destroys internal.mutex which is then
locked by a call to bdev_channel_destroy() resulting from the
earlier spdk_put_io_channel(). Move the destroy and the free of
internal.qos into bdev_destroy_cb so that they don't occur until
all of the channels have been released. Remove the no longer
required bdev_fini.
Repeat calls to spdk_bdev_unregister that occur after an unregister has
completed will lock internal.mutex which has been destroyed by the
previous unregister. This occurs during unit tests. Defer locking
internal.mutex until after the internal.status has been checked for
SPDK_BDEV_STATUS_REMOVING. This is the only place where
internal.status is set to removing and g_bdev_mgr.mutex alone is
sufficient to ensure atomicity here.
Tested with a pthreads library that contains debugging code to
check the mutex state and a modified version of bdev_io_types_test
to call get_io_channel on a different thread.

Yet it did not apply to SPDK_RPC_RUNTIME RPCs, as the
bdev module initialization was already complete.

Add spdk_bdev_abort function as a new public API.
This goes all the way down to the bdev driver module and attempts to
abort all I/Os which has bio_cb_arg as its callback argument.
We can separate when only a single I/O has bio_cb_arg and when multiple
I/Os have bio_cb_arg, but unify both by using parent - children I/O
relationship. To avoid confusion, return matched_ios by _bdev_abort() and
store it into split_outstanding by the caller.
Exclude any I/O submitted after this abort command because the same cb_arg
may be used by all I/Os and abort may never complete.
bdev_io needs to have both bio_cb_arg and bio_to_abort because bio_cb_arg
is used to continue abort processing when it is stopped due to the capacity
of bdev_io pool, and bio_to_abort is used to pass it to the underlying
bdev module at submission. Parent I/O is not submitted directly, and is
only used in the generic bdev layer, and parent I/O's bdev_io uses bio_cb_arg.
Hence add bio_cb_arg to bdev structure and add bio_to_abort to abort structure.
In the meantime of abort operation, target I/Os may be completed. Hence
check if the target I/O still exists at completion, and set the completion
status to false only if it still exists.
Upon completion of this, i.e., this returned zero, the status
SPDK_BDEV_IO_STATUS_SUCCESS indicates all I/Os were successfully aborted,
or the status SPDK_BDEV_IO_STATUS_FAILED indicates any I/O was failed to
abort by any reason.
spdk_bdev_abort() does not support aborting abort or reset request
due to the complexity for now.
Following patches will support I/O split case.
Add unit tests together to cover the basic paths.
Besides, ABI compatibility check required us to bump up SO version of
a few libraries or modules. Bump up SO version of blob bdev module simply
because it does not have any out-of-tree consumer, and suppress bumping
up SO version of lvol library because the affected struct spdk_lvol
is not part of public APIs.

When we unlock a range, we remove the range from the
locked bdev list before doing the for_each_channel
iteration to remove the range from each channel.
But at the same time, right after removing from the
locked list, a new lock on that range could start.
In that case, we also do a for_each_channel to add
the range to each channel, and that will race with
the for_each_channel remove. When the lock start
wins, it finds the range already in the channel,
but doesn't set the owner_range which results in
a seg fault when the for_each_channel completes.
The fix is actually rather simple. We just add the
locked_ctx to the comparison when checking if the
range is already in the channel. If the locked_ctx
matches, then we know it was added as part of
initializing a new channel. If it doesn't, then
we create a new range object pointing to the new
locked_ctx. The first one will get removed when
the remove for_each_channel catches up.

`spdk_bdev_io_get_buf` is used and the length of the buffer is always the same as the

Add an io_locked TAILQ to each channel, which hold
IO that will write to a currently locked region.
Also add a new step to the locking process per channel.
Each channel needs to wait until all existing outstanding
writes to the newly locked range have been completed.
Only the channel that locked an LBA range may submit
write I/O to it. It must use the same cb_arg for the
write I/O as the cb_arg used when locking the LBA range.
This ensures that only the specific I/O operations needing
the lock will bypass the lock.
When a range is unlocked, we will just blindly try to
resubmit all IO in the io_locked tailq. This could be
made more efficient in the future, but we don't expect
this path to occur very often, so going for simplicity
in the first pass.
