Valgrind showed that the disconnected paths variables were leaking
during the merge. That happened because flagvals did not implement a
destructor freeing the variables, so they leaked. flagvals cannot
implement a destructor, because that would make it a non-trivial union
member and parser_yacc.y would not compile. This patch implements a
"clear" function that is supposed to act as the destructor.

The apparmor_parser allows you to add, replace, and remove AppArmor
policy through the use of command line options. The default is to add.
`apparmor_parser --help` shows what the command line options are.
