/**
 * "struct strset" is a hashed string set: you can add strings to this
 * library, and it stores them as a set of unique strings.  You can
 * get the size of the set, and you can enumerate through all values.
 *
 * It is important to note that the strset does not copy the string
 * values - it stores the exact pointers it was given in strset_add().
