2008-09-09strset: fix duplicate valuesMax Kellermann1-1/+1
Due to a minor typo, the string set had duplicate values, because strset_add() didn't check the base slot properly.
2008-09-09added string set libraryMax Kellermann1-0/+144
"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. This will be used to replace the linear tagTracker library.
