    Extract the paramaters (in the form $N) from an access
    vector, storing them as Param objects in a dictionary.
    Some attempt is made at resolving conflicts with other
    entries in the dict, but if an unresolvable conflict is
    found it is reported to the caller.

    The goal here is to figure out how interface paramaters are
    actually used in the interface - e.g., that $1 is a domain used as
    a SRC_TYPE. In general an interface will look like this:

    interface(`foo', `
       allow $1 foo : file read;
    ')

    This is simple to figure out - $1 is a SRC_TYPE. A few interfaces
    are more complex, for example:

    interface(`foo_trans',`
       domain_auto_trans($1,fingerd_exec_t,fingerd_t)

       allow $1 fingerd_t:fd use;
       allow fingerd_t $1:fd use;
       allow fingerd_t $1:fifo_file rw_file_perms;
       allow fingerd_t $1:process sigchld;
    ')

    Here the usage seems ambigious, but it is not. $1 is still domain
    and therefore should be returned as a SRC_TYPE.

    Returns:
      0  - success
      1  - conflict found
