It's for calculating whole trace data size during reading. However relation functions are called only in this file, no need to conditionalize it with tricky +1 offset and rename the variable to more meaningful name like trace_data_size.

This introduces the tools/lib/lk library, that will gradually have the routines that now are used in tools/perf/ and other tools and that can be shared. Start by carving out debugfs routines for general use.
