 *
 * Implementation of the Wu-Manber pattern matching algorithm.
 *
 * Ideas:
 *   - the hash contains a list of patterns. Maybe we can 'train' the hash
 *     so the most common patterns always appear first in this list.
 *
 * \todo make hash1 a array of ptr and get rid of the flag field in the
 *    WmHashItem
 * \todo remove exit() calls
 * \todo only calc prefixci_buf for nocase patterns? -- would be in a
 *    loop though, so probably not a performance inprovement.
 * \todo make sure runtime counters can be disabled (at compile time)
