[0/7] Separate trace-cmd and libtracecmd code

Message

libtracecmd is a library, containing functions that can be
used without 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.

Tzvetomir Stoyanov (VMware) (7):
  trace-cmd: Move trace-output.c into the library code
  trace-cmd: Move trace-msg.c into the library.
  trace-cmd: Move trace-cmd global variable "quiet" to libtracecmd
  trace-cmd: Move trace-cmd global variable "debug" to libtracecmd
  trace-cmd: Move plog() function to libtracecmd.
  trace-cmd: Move trace-cmd APIs from trace-cmd.h to trace-local.h
  trace-cmd: Move tracecmd_stack_tracer_status() function to libtracecmd
