* Refactor: Use HtSP for storing plugins. This saves iterations when searching for a plugin of a given name. It also allows to save plugin configurations and data in hash table, all addressed by their name. Hence, usage is more streamlined. * Fix: iterators iterate over pointers of pointers. * Soften the NULL check. If arch is passed on from another struct, NULL is an allowed invalid value. * Fix some leaks * Fix NULL checks and incorrect inits * Fix more leaks * Add warning if plugin with same name was added before and is overwritten. * Document rz_str_cmp * Add function to create new list from iterator. * Sort plugins alphabetically when listed. * Fix parameter attributes, NULL checks, leaks and single rename.
