[v3,0/4] Separate trace-cmd and libtracecmd code

Message

libtracecmd is a library, containing functions that can be
used without the trace-cmd application. However, some of the
functions declared as libtracecmd APIs in trace-cmd.h
depend on trace-cmd context. That causes a problem when
other application uses the library. The problem can be
observed when running kerneshark and there is a python
module, loaded by the python plugin - there is a bunch
of warnings.
To resolve the problem, implementations of all trace-cmd
independent functions are moved into libtracecmd. All
libtracecmd functions, that depend on trace-cmd context
are removed from the library and from trace-cmd.h file.

[
  v3 changes:
   - Removed accepted patches from the series.
   - Added new patch: "Update descriptions of "debug" libtracecmd APIs".
   - Renamed "plog*" library APIs to "tracecmd_plog*".
   - Rmoved "tracecmd" prefix from local variables.
   - Renamed trace_set_log_file to tracecmd_set_logfile.
   - Changed tracecmd_set_quiet() and tracecmd_get_quiet() APIs to work
     per tracecmd_output handler.
 
  v2 changes:
   - Added a new patch: 
        Move trace-cmd-local.h from the application to the library.
   - Remove trace-output.c dependency of version.h. Moved FILE_VERSION_STRING
     define from top Makefile to trace-cmd-local.h.
