The traceevent lib is used by the perf tool, and when executing
perf test -v 6
it outputs error log on the ARM64 platform:
running test 33 '*:*'trace-cmd: No such file or directory
[...]
trace-cmd: Invalid argument
The trace event parsing code originally came from trace-cmd so it keeps
the tag string "trace-cmd" for errors, this easily introduces the
impression that the perf tool launches trace-cmd command for trace event
parsing, but in fact the related parsing is accomplished by the
traceevent lib.
This patch changes the tag string to "libtraceevent" so that we can
avoid confusion and let users to more easily connect the error with
traceevent lib.

Adding a missing copyright header to parse-utils.c. Assuminng that the
license is LGPL like the rest of the trace-cmd library code.

Copy over the files from trace-cmd to the Linux tools directory
such that applications like perf and latencytrace can use the
more advanced parsing code.
Because some of the file names of perf conflict with trace-cmd file
names, the trace-cmd files have been renamed as follows:
parse-events.c ==> event-parse.c
parse-events.h ==> event-parse.h
utils.h ==> event-utils.h
The files have been updated to handle the changes to the header files
but other than that, they are identical to what was in the trace-cmd
repository. The history of these files, including authorship is
available at the git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
The Makefile was also copied over, but most of it was removed to
focus on the parse-events code first. The parts of the Makefile for
the plugins have also been removed, but will be added back when the
plugin code is copied over as well. But that may be in its own
separate directory.
