Subject: [PATCH v3 06/12] tracing: expose structure ftrace_event_field

From: "zhangwei(Jovi)" <jovi.zhangwei@...wei.com>

Currently event tracing field information is only stored in
struct ftrace_event_field, this structure is defined in
internal trace.h.
Move this ftrace_event_field into include/linux/ftrace_event.h,
then external modules can make use this structure to parse event
field(like ktap).
