libihash: reduce the default maximum load factor to 75%
The performance of hash tables depend critically on a low number of
hash collisions. As the table fills up, the chance of collisions
necessarily raises.
Previously, libihash resized the hash table when the load exceeded
80%. This seems a bit optimistic (e. g. java.util.Hashtable uses 75%
as default).
* libihash/ihash.h (HURD_IHASH_MAX_LOAD_DEFAULT): Set to 75.
