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.

Previous patches (5363eb3c) tried to work around the
32-bit unmap and write_zeroes LBA counts by breaking
up larger operations into smaller chunks of max size
UINT32_MAX lba chunks.
But some SSDs may just ignore unmap operations that
are not aligned to full physical block boundaries -
and a UINT32_MAX lba unmap on a 512B logical /
4KiB physical SSD would not be aligned. If the SSD
decided to ignore the unmap/deallocate (which it is
allowed to do according to NVMe spec), we could end
up with not unmapping *any* blocks. Probably SSDs
should always be trying hard to unmap as many
blocks as possible, but let's not try to depend on
that in blobstore.
So one option would be to break them into chunks
close to UINT32_MAX which are still aligned to
4KiB boundaries. But the better fix is to just
change the unmap and write_zeroes APIs to take
64-bit arguments, and then we can avoid the
chunking altogether.
Fixes issue #2190.

spdk_bdev_create_bs_dev_ext() gets not bdev pointer but bdev name
as an argument, and hence vbdev_lvs_create() will get bdev name
accordingly.
However after completing spdk_bdev_create_bs_dev_ext(),
vbdev_lvs_create() has to get bdev pointer from the created bs_dev.
Hence add a function pointer get_base_bdev to struct spdk_bs_dev
and set it to bdev_blob_get_base_bdev() at initialization.

spdk_bdev_open_ext() requires the caller to use bdev_event_cb_t
and bdev_event_cb_t is more extensible than bdev_remove_cb_t.
Hence use bdev_event_t as an argument.
spdk_bdev_open_ext() calls spdk_bdev_get_by_name() inside and
spdk_bdev_create_bs_dev_ext() calls spdk_bdev_open_ext() inside.
The caller needs to know if the spdk_bdev_get_by_name() succeeded.
Hence spdk_bdev_create_bs_dev_ext() returns return code by return
value and returns the created bs_dev by double pointer.
