8dd1cd2104 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.

488570ebd4 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.

a876c45f07 llvm_nvme_fuzz: add -N option to specify data input file
If the fuzzer crashes or hangs, LLVM spits out a file
containing the raw data input for the iteration that
caused the crash or hang.  Add a -N option to
llvm_nvme_fuzz to allow the user to specify one of these
files.  When specified, the fuzzer will only run one
iteration with that specific input data.

17dd532ff7 llvm_nvme_fuzz: raise SIGSEGV if user Ctrl-C
If an input causes a hang, the fuzzing thread won't
terminate itself, since it is waiting for all
outstanding commands to complete.  So raise a SIGSEGV
in the SPDK shutdown handler instead, which will
cause the fuzzer thread to exit as well as generating
an input file of the hung input.

0674ead739 llvm_nvme_fuzz: add exit handler
When the LLVM fuzzer is done, it calls exit(0)
explicitly.  This triggers the DPDK exit handler
to run which starts unmapping huge pages while
our reactor thread is still running.

Currently, this doesn't cause any problems since
the fuzzing thread and reactor thread are running
on the same core.  But the next patch will
unaffinitize the fuzzing thread, meaning that the
reactor thread will be actively trying to read
hugepage memory while the fuzzing thread is in
DPDK exit handlers unmapping that same memory.

7610bc38dc scripts: move python modules to python directory
Up until now, importing an SPDK RPC python module was just a matter of
`import rpc`.  It's fine until there's another module called `rpc`
installed on the system, in which case it's impossible to import both of
them.  Therefore, to avoid this problem, all of the modules were moved
to a separate directory under the "spdk" namespace.

The decision to move to a location under a separate directory was
motivated by the fact that a directory called scripts/spdk would look
pretty confusing.  Moreover, it should make it also easier to package
these scripts as a python package.

Other than moving the packages, all of the imports were updated to
reflect these changes.  Files under python now use relative imports,
while those under scripts/ use the "spdk" namespace and have their
PYTHONPATH extended with python directory.

050565e5ab test/nvmf: fuzz nvmf target using LLVM's libFuzzer
LLVM provides libFuzzer which does coverage-guided
fuzzing of a library or application under test.  For
SPDK, we can use this as a new and better way to
generate random commands to the SPDK nvmf target.

By default, libFuzzer provides the main() and your
source file just provides the function called by
LLVM for each iteration of random data.  But this
doesn't really work for SPDK since we need to start
the app framework and the nvmf target.  So we
specify -fsanitizer=fuzzer-no-link, explicitly
specify the location of the fuzzer_no_main library
and then call LLVMFuzzerRunDriver to start the
fuzzing process once we are ready.

Since this is all coverage-guided, we invoke the
fuzzer inside the nvmf target application.  So this
patch creates a new target application called
'llvm_nvme_fuzz'. One core is needed to run the
nvmf target, then we spawn a pthread to run the
fuzzer against it.

Currently there are two fuzzers defined.  Fuzzer 0
does random testing of admin commands.  Fuzzer 1
is focused solely on GET_LOG_PAGE and fuzzes a
smaller subset of the bytes in the spdk_nvme_cmd.

Additional fuzzers can be added in the future for
other commands, testing I/O queues, data payloads,
etc.

You do need to specify CC and CXX when running
configure, as well as specify the location of the
special clang_rt.fuzz_no_main library. The path of
that library is dependent on your clang version and
architecture. If using clang-12 on x86_64 platform,
it will look like:

CC=clang-12 CXX=clang++-12 ./configure --with-fuzzer= \
  /usr/lib/llvm-12/lib/clang/12.0.0/lib/linux/libclang_rt.fuzzer_no_main-x86_64.a

Then just do the following to demonstrate the fuzzer
tool.

make
test/nvmf/target/llvm_nvme_fuzz.sh --time=60 --fuzzer=0

just add a -F option that tells the nvme_fuzz app which
subsystem(s) to fuzz.  This simplifies the fuzz_app code
a bit and makes it a bit easier to use.

d132ee3531 build: use DEPDIRS variables to build SPDK_LIB_LIST
All of our Makefiles duplicate huge lists of libraries
in SPDK_LIB_LIST.  We have a very precise and accurate
accounting of the library dependencies in
mk/spdk.lib_deps.mk which can be used to generate
the full list if the app specifies the modules and
subsystem libraries it wishes to link.

I did a first pass through all of the existing
Makefiles to take advantage of this new functionality.
There may be more optimizations we can make later but
don't want to hold up this patch for all of them.
