fcpat: Increase the number of buckets in the shared string hash table
This is a reasonably conservative increase in the number of buckets in the hash table to 251. After FcInit(), there are 240 shared strings in use on my system (from configuration files I assume). The hash value is stored in each link in the chains so comparison are actually not very expensive. This change should reduce the average length of chains by a factor of 8. With the reference counted strings, it should keep the average length of chains to about 2. The number of buckets is prime so as not to rely too much on the quality of the hash function. https://bugs.freedesktop.org/show_bug.cgi?id=17832#c5 Patch from Karl Tomlinson
