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.

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.

(to_next_boundary_bytes % blocklen) meant not to_last_block but to_next_block.
So calculate to_last_block_size by reducing to_last_block_size from blocklen.
The data was collected when the issue occured. So add unit test
by using the data.

This patch adds new interface for opening bdev and
implements new style remove event. With that changes
user can be notified about different types of events
that occur in regards to bdev. spdk_bdev_open_ext
function uses bdev name as an argument instead of bdev
structure to remove race condition where user gets
the bdev structure and bdev is removed after getting
that structure and before open function is called.
spdk_bdev_open is now deprecated.

Here is the an example to describe existing issue:
There is a Write request with 64KiB data length, and this IO is cross the IO
boundary. We assume that the parent IO will have 2 children requests, one is
33KiB length, the other one is 31KiB. Here is the view of parent iovs, the
first 33KiB length data has 33 iovs:
iov.[0].iov_length = 1024;
.
.
iov.[31].iov_length = 256;
iov.[32].iov_length = 768;
.
.
iov.[64].iov_length = 1024;
In function _spdk_bdev_io_split(), then you can see that for the 33KiB length
child request, exiting code will run out of child child_iov space and return
error due to last one data buffer is not block size aligned.
Here we can rewind the existing offset to last block size aligned buffer to
avoid the error case, for backend which need aligned data buffer such as
AIO backend, the request will go through spdk_bdev_io_get_buf() again to
do the data copy, otherwise for those backend devices such as NVMe with
hardware SGL support, 256 data segment is fine for them.

Existing code in spdk_bdev_write_zeroes_blocks() will call spdk_bdev_free_io()

avoid the error case.

Add a case that was not tested before. In this case, the length of the

Expect the rest of iovec array to be submitted in the completion of
