When a new cluster is added to a thin provisioned blob,
md_page is allocated to update extents in base dev
This memory allocation reduces perfromance, it can
take 250usec - 1 msec on ARM platform.
Since we may have only 1 outstainding cluster
allocation per io_channel, we can preallcoate md_page
on each channel and remove dynamic memory allocation.
With this change blob_write_extent_page() expects
that md_page is given by the caller. Sicne this function
is also used during snapshot deletion, this patch also
updates this process. Now we allocate a single page
and reuse it for each extent in the snapshot.

To fix issue: #2484
When unregistering the bdev, will send out the message
to each thread to abort all the IOs including IOs from
nomem_io queue, need_buf_small queue and need_buf_large queue.
The new SPDK_BDEV_STATUS_UNREGISTERING state is newly
added to indicate this unregister operation.
In this case, the bdev unregister operation becomes the
async operation as each thread will be sent the message
to abort the IOs and as the last step, it will unregister
the required bdev and associted io device.
On the other hand, the queued_resets will be handled
separately and not aborted in the bdev unregister.
New unit test cases are also added:
enomem_multi_bdev_unregister: to abort the IO from
nomem_io queue during the unregister operation
bdev_open_ext_unregister: to handle the events and
async operations from the unregister operation

A recent change to the bdevio test changed one of the
tests from a 30x4K IO to a 30xLBA IO.
This has started giving us nightly test failures (see
issue #2499). It is because now the 30 * LBA (512B)
is 15KB which all fits within one 16KiB reduce chunk,
yet we only allocate REDUCE_MAX_IOVS
(17) iovs per reduce IO context. Previously when
they were 4KiB each, we would only need 4 iovecs
(16KiB / 4KiB).
We may need to think through this a bit more, to
make this more dynamic (based on the chunk size
and underlying block size), but for now let's at
least increase this enough to handle the most
common 16KiB chunk / 512B LBA case.
While here, run bdevio as part of per-patch testing,
that would have helped us catch this issue before the
a6e022463 patch got merged.
Fixes#2499.

If we specify a preferred path manually for each NVMe bdev, we will
be able to realize a simple static load balancing and make the failover
more controllable in the multipath mode.
The idea is to move I/O path to the NVMe-oF controller to the head of
the list and then clear the I/O path cache for each NVMe bdev channel.
We can set the I/O path to the I/O path cache directly but it must be
conditional and make the code very complex. Hence, let find_io_path() do
that.
However, a NVMe bdev channel may be acquired after setting the preferred
path. To cover such case, sort the nvme_ns list of the NVMe bdev too.
This feature supports only multipath mode. The NVMe bdev module supports
failover mode too. However, to support the latter, the new RPC needs to
have trid as parameters and the code and the usage will be come very
complex. Add a note for such limitation.
To verify one by one exactly, add unit test.

When the LLVM fuzzer is done, it calls exit(0)
explicitly. This triggers the DPDK exit handler
to run which starts unmapping huge pages while
our reactor thread is still running.
Currently, this doesn't cause any problems since
the fuzzing thread and reactor thread are running
on the same core. But the next patch will
unaffinitize the fuzzing thread, meaning that the
reactor thread will be actively trying to read
hugepage memory while the fuzzing thread is in
DPDK exit handlers unmapping that same memory.

blockdev_compare_and_write and blockdev_write_read check
if data_length is multiple of block size and silently
succeed if it is not. There are multiple test that test
e.g. invalid size but the actual bdev API is
never called and tested because of the early return.
The intend of this behavior presumably was to allow
to run test like e.g. the 512bytes rw test on a 4K
formatted namespace without failing. Instead of silently
succeeding which introduces the issues described this
patch changes all sizes to be multiple of block size and
removes the test for valid block size to let the
return value of the bdev API functions indicate failure like
intended. All previous 4k tests are now performing io of
1 block size. Previous 512byte tests now perform
8 * block size (to have 4k test size for 512byte formatted
namespaces). Write zeroes test are now using the
write zeroes buffer size instead of a hardcoded value
and align accordingly to block size io.
Furthermore, no cmp&write test is ever executed because
data_length is set to 1 trying to indicate 1 block but
it is tested against valid block bytes and silently
succeeded. Also write and read helpers in cmp&write test
expect bytes not blocks. For consistency use bytes in the
test and only convert to blocks when calling the cmp&write
blocks API.

The bdevio test app has some test cases verifying
that write zeroes commands are handled correctly,
but using knowledge of the ZERO_BUFFER_SIZE that
the bdev library uses for splitting larger write
zeroes commands. Instead of hardcoding that 1MB
value in bdevio.c, have bdevio.c use ZERO_BUFFER_SIZE
directly instead. But this requires moving
ZERO_BUFFER_SIZE into bdev_internal.h and having
bdevio.c include that file.
We do this instead of putting ZERO_BUFFER_SIZE in
the public API because we don't want users to
make any kind of dependencies on this value.
While here, also rename the tests that are using this
value, so that the test names don't include any reference
to the specific size of this bdev-internal zero buffer
size.

When sending a fused compare and write command, we pass a callback
bdev_nvme_comparev_and_writev_done that we expect to be called twice
before marking the io as completed. In order to detect if a call to
bdev_nvme_comparev_and_writev_done is the first or the second one, we
currently rely on the opcode in cdw0. However, cdw0 may be set to 0,
especially when aborting the command. This may cause use-after-free
issues and this may call the user callbacks twice instead of once.
Use a bit in the nvme_bdev_io instead to keep track of the number of
calls to bdev_nvme_comparev_and_writev_done.

To avoid this failure, defer calling spdk_io_device_unregister() until

function is added to convert from opcode to bit position. Right
now it is used in the IO path but in upcoming patches that goes away

Previously spdk_vhost_dev_backend held callbacks
for vhost_blk and vhost_scsi functionality, along
with ones that are called by the vhost_user backend.
This patch separates out those callbacks into two
structures:
- spdk_vhost_dev_backend - to be implemented by vhost_blk
and vhost_scsi
- spdk_vhost_user_dev_backend - is only implemented by
vhost_user backend, callbacks for session managment
specific to that transport

Up until now, importing an SPDK RPC python module was just a matter of
`import rpc`. It's fine until there's another module called `rpc`
installed on the system, in which case it's impossible to import both of
them. Therefore, to avoid this problem, all of the modules were moved
to a separate directory under the "spdk" namespace.
The decision to move to a location under a separate directory was
motivated by the fact that a directory called scripts/spdk would look
pretty confusing. Moreover, it should make it also easier to package
these scripts as a python package.
Other than moving the packages, all of the imports were updated to
reflect these changes. Files under python now use relative imports,
while those under scripts/ use the "spdk" namespace and have their
PYTHONPATH extended with python directory.

This test reproduced issue #2428. It does the following:
1) submit some large writes (requiring R2T or RDMA READ)
2) submit fused compare (first fused)
3) variable number of qpair polls
4) submit fused write (second fused)
The RDMA and TCP transports were not accounting for the
fused bits, and would send a non-fused command down to
the target layer between the two fused commands.
By adding the variable amount of delay between the fused
command submissions, it creates a window where a large
write's payload is fetched from the host and submitted
to the target between submission of the two fused commands.

The concat module can combine multiple underlying bdevs to a single
bdev. It is a special raid level. You can add a new bdev to the end of
the concat bdev, then the concat bdev size is increased, and it won't
change the layout of the exist data. This is the major difference
between concat and raid0. If you add a new underling device to raid0,
the whole data layout will be changed. So the concat bdev is extentable.
