[PATCH v3 01/11] libtracefs: Add new public macros for bits manipulations

["Tzvetomir Stoyanov (VMware)" <tz.stoyanov@gmail.com>]

Some of the tracefs library APIs may have bit mask parameters. To
simplify the usage of such APIs, generic bit manipulations macros are
added to the library API:
 TRACEFS_BIT_SET
 TRACEFS_BIT_TEST
 TRACEFS_BIT_CLEAR
