Tzvetomir Stoyanov (VMware) 266b851cc2 tools lib traceevent, perf tools: Split trace-seq related APIs in a separate header file
In order to make libtraceevent into a proper library, all its APIs
should be defined in corresponding header files.  This patch splits
trace-seq related APIs in a separate header file: trace-seq.h
