There is a pevent_data_comm_from_pid() that returns the cmdline stored for a given pid in order for users to map pids to comms, but there's no method to convert a comm back to a pid. This is useful for filters that specify a comm instead of a PID (it's faster than searching each individual event). Add a way to retrieve a comm from a pid. Since there can be more than one pid associated to a comm, it returns a data structure that lets the user iterate over all the saved comms for a given pid.
