The ftrace event format parser handles the usual casts but not
the cast to pointers. Such casts have been introduced recently
with the module trace events and raise the following parsing
error:

	Fatal: bad op token )

This is because it considers the "*" character as a binary
operator. Make it then aware of casts to pointers.

Add util/trace-event-parse.c which provides the handlers to
parse the ftrace events info from the stream and handles the
ftrace perf samples event printing.

This file is a rename of the parse-events.c file from the
trace-cmd tools, written by Steven Rostedt and Josh Triplett,
originated from the git tree:

  git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git

This is a perf tools integration.
