From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx>
Add %define api.prefix and defines to have the parser global variables use
tracefs_* instead of yy*, as without this, if a tool that links to this
library, and tries to use the synth sql parsing, it may end up using its
own yyparse() and friends functions.
