3408399172 sma: added tweak mode in sma crypto
AES-XTS requires providing tweak. By definition tweak (128bits)
represents logical position of the data being encrypted or decrypted,
typically for nvme it is LBA.
Various implementations of AES-XTS can treat that requirment
in different way, because AES-XTS specification doesn't define
how exactly tweak look like and how exactly LBA is transformed
into tweak  For example:
 - Tweak[127:0] = {1’b0, ~LBA[62:0], LBA[63:0]}
 - Tweak[127:0] = {LBA[127:0] + 1}
 - Tweak[127:0] = {LBA[63:0] + 1, 64'b0}

So there's a need of specifying mode of tweak

b7964a3c5a sma: forbid deleting devices with attached volumes
It makes it possible for stateless clients to send CreateDevice /
DeleteDevice each time a volume is attached / detached.  Deleting a
device with attached volumes results in FAILED_PRECONDITION error, which
a client can simply ignore.  The device will be deleted during the final
DeleteDevice call, once all volumes are detached.

We limit this behavior to device types that support AttachVolume /
DetachVolume methods, otherwise it would be impossible to delete such
devices.

a6dbe3721e update Intel copyright notices
per Intel policy to include file commit date using git cmd
below.  The policy does not apply to non-Intel (C) notices.

git log --follow -C90% --format=%ad --date default <file> | tail -1

and then pull just the 4 digit year from the result.

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)
block with a blank comment line so these were added as the vast
majority of files do have this last blank line.  Simply there for
consistency.

c996aff28d build: move protobuf files to a top-level directory
Up until now, the protobuf files were all located under
`python/spdk/sma/proto`.  This was fine, as they were only used in SMA
and we only generated python code.  However, now, we would also like to
to output code for other (e.g. go) languages too, so it no longer make
sense to keep them under `python`.

Only the protobuf files will be stored under `proto`.  The autogenerated
python code will remain under `python`, while the go code will be put in
the `go` directory.

While here, simplified the Makefile by removing a function generating
rules based on a directory, because we keep all protobuf files in the
same location.
