It is now possible to submit a write request with a sequence of accel
operations that need to be executed before actually writing the data.
Such requests will be directly passed to a bdev module (so that it can
append subsequent operations to an accel sequence) if that bdev supports
accel sequences and the request doesn't need to be split. If either of
these conditions are not met, bdev layer will execute all the
accumulated accel operations before passing the request to a bdev
module.
The reason for not submitting split IOs with an accel sequence is that
we would need to split that accel sequence too. Currently, there's no
such functionality in accel, so we treat this case in the same way as if
the underlying bdev module didn't support accel sequences (it's executed
before bdev_io is split).

Modules can now report that they support accel chaining for specific
operations through the accel_sequnce_supported() callback.
The support is reported per IO type. This allows modules to support
accel sequences for some operations, while relying on the bdev layer to
handle them for other IO types.
Only bdevs without separate metadata buffers are allowed to support this
new mode. That's because metadata in separate buffer is expected to use
the same memory domain as data buffers. With an accel sequence, those
data memory domains can change, while metadata's memory domain always
stays the same. To support bdevs with separate metadata buffers, we'd
need to add separate pointers for metadata's memory domain. For now,
simply disallow registering bdevs with separate metadata supporting
accel sequences.

The spdk_bdev_ext_io_opts structure is used to pass extra options when
submitting a bdev IO request, without having to modify/add functions to
handle new options. Additionally, the structure has a size field to
allow adding new fields without breaking the ABI (and thus having to
bump up the major version of a library).
It is also a part of spdk_bdev_io and there are several reasons for
removing it from that structure:
1. The size field only makes sense in structures that are passed
through pointers. And spdk_bdev_ext_io_opts is indeed passed as a
pointer to spdk_bdev_{readv,writev}_blocks_ext(), however it is
also embedded in spdk_bdev_io (internal.ext_opts_copy), which is
also part of the API. It means that each time a new field is added
to spdk_bdev_ext_io_opts, the size of spdk_bdev_io will also
change, so we will need to bump the major version of libspdk_bdev
anyway, thus making spdk_bdev_ext_io_opts.size useless.
2. The size field also makes internal.ext_opts cumbersome to use, as
each time one of its fields is accessed, we need to check the size.
Currently the code doesn't do that, because all of the existing
spdk_bdev_ext_io_opts fields were present when this structure was
initially introduced, but we'd need to do check the size before
accessing any new fields.
3. spdk_bdev_ext_io_opts has a metadata field, while spdk_bdev_io
already has u.bdev.md_buf, which means that we store the same thing
in several different places in spdk_bdev_io (u.bdev.md_buf,
u.bdev.ext_opts->metadata, internal.ext_opts->metadata).
Therefore, this patch removes all references to spdk_bdev_ext_io_opts
from spdk_bdev_io and replaces them with fields (memory_domain,
memory_domain_ctx) that were missing in spdk_bdev_io. Unfortunately,
this change breaks the API and requires changes in bdev modules that
supported spdk_bdev_io.u.bdev.ext_opts.

Copy operation is defined by source and destination LBAs and LBA count
to copy. For destiantion LBA and LBA count we reuse exiting fields
`offset_blocks` and `num_blocks` in `struct spdk_bdev_io`. For source
LBA new field `src_offset_blocks` was added.
`spdk_bdev_get_max_copy()` function can be used to retrieve maximum
possible unsplit copy size. Zero values means unlimited. It is allowed
to submit larger copy size but it will be split into several bdev IOs.

A new parameter io_drain_timeout has been added to spdk_bdev
structure. If this value is unset, the bdev reset behavior
does not change.
The io_drain_timeout controls how long a bdev reset must wait for IO
to complete prior to issuing a reset to the underlying device.
If there is no outstanding IO at the end of that period, the reset
is skipped.

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.

Some use cases want to abort every bdev_io submitted to the bdev by
traversing the bdev channels.
However, struct spdk_bdev_channel is private in lib/bdev/bdev.c.
Hence, add a helper function spdk_bdev_for_each_bdev_io() to execute
the function on the appropriate thread for every bdev_io submitted
to the bdev.
This function should be used only from the bdev module and it should
be ensured that the bdev is not unregistered during execution.
We keep this function as generic as possible because we may have
other use cases in future.

Fix issue: #2561
The issue here is that in the bdev_set_qd_sampling_period RPC
command, the QD sampling period has been set. Then later the
related Desc is closed and in the bdev_close() function the
QD sampling period is reset to 0.
A new QD desc is added as the QD sampling period update could
be handled properly.
Meanwhile, a new QD Poll In Progress flag is also added so as
to indicate there are ongoing events of QD sampling and the
Bdev unregister will be handled in the proper way.
Related test case and unit test also updated for this change.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

To unregister a bdev more correctly, we had to call
spdk_bdev_open_ext(), spdk_bdev_desc_get_bdev(), spdk_bdev_unregister(),
and then spdk_bdev_close(). This was correct but complicated.
Hence add a new public API spdk_bdev_unregister_by_name() which does
the whole correct sequence of bdev unregistration.
