Replaced direct calls to the CUnit's functions to run the tests with

a specific test case.

The blob.c unit test wasn't changed, because it runs all tests multiple
times with different parameter combinations, so it cannot be easily
converted. In the future, each such combination could be split into a
separate test suite, which would make it compatible with
spdk_ut_run_tests().

Intel copyrights were not added to files where Intel either had

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

check_format: For C files only, fix return type breaks

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:

1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names

Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

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.

If the backing device doesn't support SGL input then
we should copy user's buffers into decomp_buffer

In the decompression operation, if the backing device
doesn't support SGL output, we use a single output buffer
which is pointing to decomp_buffer. Once the operation
completes, we should copy the result into user's buffers.

test: add generic unlink wrapper

reduce library uses unlink, but the unit tests need to
override it in a specific way.

But linking unit tests with LTO requires the wrapper
definitions be in objects/libraries listed *after*
the object/library that refers to it. So we need to
make the unlink wrapper somewhat generic. We do this
by exporting a string and callback function that the
user can set to enable a user-defined function to be
called when unlink() is called with a specific file
name.

Also revert 3ef6d06 as part of this patch, since we
no longer require the workaround that it implemented.

Fixes issue #1357.

The unit tests to this point used an algorithm that

Change it now to use the actual unit test compression

A few unit tests need to be modified to account
for the compressible buffers - primarily those that
write a single 512 byte LBA in a 16KB chunk. These
will now be compressed down to a single I/O unit,
so some of the asserts need to be changed to adjust
for this.

This test verifies that all of the io_unit_index[] entries
are written. For that to really happen, the write for
the chunks must not be compressible. Currently the compress
algorithm just copies the data and doesn't actually
compress - so writing a partial chunk works OK for this test.
But upcoming patches will add a 'real' compression unit test
algorithm - at which point, writing just part of a chunk
will be compressible since the non-written parts will be all
zero.
