tools lib api: Add debug output support

Adding support for warning/info/debug output within libapi code. Adding
following macros:

  pr_warning(fmt, ...)
  pr_info(fmt, ...)
  pr_debug(fmt, ...)

Also adding libapi_set_print function to set above functions. This will
be used in perf to set standard debug handlers for libapi.

Adding 2 header files:
  debug.h
    - to be used outside libapi, contains
      libapi_set_print interface

  debug-internal.h
    - to be used within libapi, contains
      pr_warning/pr_info/pr_debug definitions
