blob: Add support for variable metadata page size

Currently SPDK blobstore depends on 4KB atomicity of metadata.
So, Metadata page size will be made variable based on the physical
block size reported by the underlying device. This will enable
blobstore to store metadata in IU-sized chunks, not always 4KB.

blobstore.c uses SPDK_BS_PAGE_SIZE (4KB) hardcoded at many places.
To remove this make the metadata page size variable,
phys_blocklen is added to spdk_bs_dev struct and
md_page_size is added to spdk_bs_super_block struct.

test/unit/blob: do not make assumptions about first data cluster

A bunch of blobstore unit tests make assumptions that the first
data cluster is cluster index 1 (meaning cluster index 0 contains
all of the metadata).

But to support variable metadata page sizes, this assumption is no
longer valid. For example, with 16KB metadata page sizes, the
metadata will take up more than 1 cluster.

So improve the unit tests to remove assumptions in this area.

Up until now, the unit tests were all just hardcoded for 4096B md
page size. Upcoming patches will enable larger md page sizes. So
introduce a suite parameter "g_phys_blocklen" which for now will
always be 4096. Future patches will emulate block devices with a
larger phys_blocklen, which is used as the md page size by default.

Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license
header updates, formatting changes, etc). Contribution date used
"--follow -C95%" to get the most accurate date.

Note that several files in this patch didn't end the license/(c)

Replace most BSD 3-clause license text with SPDX identifier.

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.

blob: use uint64_t for unmap and write_zeroes lba count

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.

lib/blob: use bs_allocate_and_copy_cluster() in inflate

Using `bs_allocate_and_copy_cluster()` instead of a zero-length write
makes it possible to inflate/decouple snapshots, as the writes would
fail with -EPERM, because the snapshots are marked as read-only.

Additionally, zero-length non-vector requests are now completed
immediately. It makes it consistent with the vector path (which already
does that) and allows us to use the zero-length reads as a context for
cluster copy.

Fixes #2028.

This is a very hot function in the main I/O path,
