tools/events: Add files to create libtraceevent.a
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.
