Remove some tokens the lexer never produces. Ensure abort paths set an error. Previously scanning all PMUs meant bad events could fail with an invalid token, detect this at the point parsing for a PMU fails and add error strings. Try to be consistent in using YYNOMEM for memory failures and YYABORT for bad input.
