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
