lib/trace: add extra check in trace parser when determining first entry

If we simply set _tsc_offset to the highest first_tsc out of
all reactors when none have overflowed its circular buffer,
it will cut off the first few entries of the scheduler tracepoints.

For example, if we have 4 reactors with reactor 0 as the scheduling
reactor, reactor 0 will emit a SCHEDULING_PERIOD_START trace,
as well as its CORE_STATS and THREAD_STATS. Then reactors 1-3 will
do the same. When we parse the trace, the first
SCHEDULING_PERIOD_START, CORE_STATS, and THREAD_STATS of reactors
0, 1, and 2 will be erased because reactor 3 started last and
has the highest first_tsc.

Therefore, we need to check if any reactors have overflowed their
circular buffer before truncating the entries.

trace_parser: wrong parameter to sizeof() operator

The issue was detected by Coverity scan.

After changing spdk_trace_parser_entry structure layout,
checking size of the union was not modified, resulting in
wrong value used to determine if 'argoff' is still valid.
This in turn could lead to out-of-bound access to
pe->args[].u.string[] table as 'argoff' could be greater
than a table size.
The parameter passed to sizeof() operator shall be
'pe->args[0].u.string', not 'pe->args[0]'.

trace_parser: add flag for arguments used for related objects

Some tracepoints have an argument that is a context pointer for some other
object type. The trace app already decode this information, showing the ID for
that related object.

Since the ID is already shown, the context pointer itself isn't useful, so
add a flag to note those arguments, so we can omit printing the context
pointer.

trace: allocate shm filesize based on number of cores used

Previously we would always allocate the shm file based on
max (128) cores which is unnecessary. So use
spdk_env APIs to only allocate shm file size based
on the cores we might possible use.

With default settings, an shm file was 135MB before this
change, now an app using cores 0-7 will just use
about 9MB.

A lot of the trace-related code depended on there
*always* being a history for every core, even unused
ones, so a few additional changes were needed,
mainly the trace_parser library.

Tested by starting an app using a 0x4 core mask and
enabling a trace mask, generating some events, then
checking both the size of the shm file and that
spdk_trace works properly with the resulting file.

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.

lib/trace_parser: add trace_parser library stubs

This library will provide functions that parse traces recorded by an
SPDK application. This includes merging traces from multiple cores,
sorting them by their timestamp and constructing trace entries spanning
across multiple buffers. All of these tasks are currently implemented
in the spdk_trace app, so most of its code will be moved here (this is
the reason for using C++).

The motivation for extracting this code to a library is to be able to
use it from places other than the spdk_trace app, specifically the
`scripts/bpf/trace.py` script.

The main reason for creating a separate library instead of extending
libtrace is to avoid pulling in all of its dependencies. ISA-L is the
most problematic, as we only build it as a static library, which makes
it impossible to use with dlopen (making it unusable in scripts).
